00:00:00Now, it's obvious who can win a fight between a bee and a giant hornet.

00:00:04It's like a battle between a kitten and a saber-toothed tiger.

00:00:08And an army of bees against an army of hornets is like hundreds of kittens against hundreds

00:00:13of lions.

00:00:14It seems the hornets will win because one hornet can destroy more than 1,000 bees in

00:00:19less than an hour and a half.

00:00:21But if this battle happens in real life, it will be more complicated, dramatic, and unexpected

00:00:26than you can imagine.

00:00:28A group of bees works all day.

00:00:30They pollinate plants and fruits and collect nectar from flowers.

00:00:34They work hard and return home to the hive at the end of the day.

00:00:38They don't notice an imposter flying among them – a giant hornet.

00:00:42It's bigger than one bee but has the same yellow-black color.

00:00:46No one pays any attention to it.

00:00:48The imposter enters the bee house without an invitation and makes a crackling sound.

00:00:53That's how its jaws snap.

00:00:55Hungry and angry, it begins the feast.

00:00:58In a matter of seconds, the hornet puts the hive into chaos.

00:01:02The hornet has a sting with toxic venom, but it can go without it here.

00:01:06For bees, the monster uses its sharp jaws.

00:01:10The hive's citizens attack the enemy, but it doesn't feel a thing.

00:01:13The situation is getting worse because bees can't live after using their sting.

00:01:18They sacrifice their lives to protect their home, to protect the queen.

00:01:23Unfortunately, all their attempts are in vain.

00:01:26After quenching its thirst, the hornet flies away to find new prey.

00:01:31Only one bee manages to survive.

00:01:33It escapes from the hive to warn the others.

00:01:36The bee visits every hive in the valley and reports the powerful enemy.

00:01:40All bees start preparing to attack.

00:01:42They're raising an army.

00:01:44Unfortunately, this is not enough.

00:01:47The giant hornet visits a new hive, but this time, bees are ready.

00:01:52They attack the enemy from all sides.

00:01:54For a moment, it seems bee stings are working.

00:01:57The hornet is weakening, its activity is falling.

00:02:00The hope of victory inspires bees with confidence.

00:02:04But not for long.

00:02:05At this moment, 10 other hornets fly into the hive.

00:02:09The first hornet marked the hive with a unique pheromone before the battle.

00:02:13This smell attracted its friends, and now the bees have no chance.

00:02:18In the wild, hornets leave the trace so others can find the tagged location.

00:02:23Within a few minutes, 11 hornets destroy the hive of 25,000 bees.

00:02:28Recently, this sunny land was blooming thanks to bees.

00:02:32Now it has turned into a lifeless valley.

00:02:35Giant hornets don't want to spend time searching for hives.

00:02:39So they divide into groups and fly to different sides of the valley.

00:02:43They mark bee houses with the pheromone and start a large-scale cleanup.

00:02:47Their hunger and thirst for destruction are insatiable.

00:02:51Yeah, bees now know their enemy and notice it as soon as a hornet appears in the air.

00:02:56But it doesn't help.

00:02:57In each battle, they use a lot of strategies to fight it.

00:03:01Once bees tried to attack a hornet hive, but it was a pointless mission.

00:03:06No one pollinates flowers anymore.

00:03:08No one makes honey.

00:03:10Bees live in fear and are afraid to fly out of their hives.

00:03:13In this dark hour, when almost no hope is left, a slight chance of victory appears.

00:03:19A species of Japanese bees learned to defeat the enemy.

00:03:23The news spread all over the hives.

00:03:26The strategy seems to be working.

00:03:28They've managed to fight off several giant hornets.

00:03:31The fear goes away, and the bees are ready to fight again.

00:03:35In the real world, these bees learned to fight giant hornets.

00:03:39But other species can't do that.

00:03:41So bees are waiting for the enemy.

00:03:44They all know what to do.

00:03:45Finally, a giant hornet appears.

00:03:48Hundreds of bees attack it and wrap it with their bodies from all sides.

00:03:52They completely cover the hornet and start to tremble.

00:03:56The simultaneous vibration of all the bees heats up the enemy.

00:04:00The temperature is getting higher.

00:04:02The hornet can't get out.

00:04:04Bees seem to burn it with the energy of their bodies.

00:04:07A few minutes later, the giant hornet falls.

00:04:11Bees throw it out of the hive.

00:04:13Now they are confident of their victory.

00:04:16Another hornet arrives.

00:04:18Giant bees attack it and start to vibrate again.

00:04:21The next monster is coming.

00:04:22And another one.

00:04:2310, 20, 100 hornets arrive.

00:04:27Bees don't have so many resources and energy.

00:04:30The chances to win are zero again.

00:04:32To win once and for all, the bees must unite.

00:04:36All the hives, hundreds of millions of bees.

00:04:39A huge lifeless meadow is the location for the final battle.

00:04:44All the bees of the valley flock here.

00:04:46They are ready for the last fight.

00:04:49Silence ensues.

00:04:50Then, the air begins to vibrate.

00:04:54You can hear the buzzing of hornets from afar.

00:04:56They have increased their population hundreds of times because none of the animals can resist

00:05:01them.

00:05:02The defeat of bees is inevitable.

00:05:05But no one is going to back down.

00:05:07Two swarms collide with each other.

00:05:10This is not a battle.

00:05:11This is destruction.

00:05:14Hundreds of thousands of bees, but zero hornets fall to the ground in a few minutes.

00:05:18A whole species of insects are disappearing from the planet.

00:05:22But what is it?

00:05:24The field plugs into a strange fog.

00:05:27Bees and hornets don't see each other.

00:05:29Then, through the white veil, they appear.

00:05:32Silhouettes of giant creatures.

00:05:35They come into the middle of the action.

00:05:38Thousands of hornets attack them, but it's all pointless.

00:05:41Bees quickly fall down and lose consciousness.

00:05:44The hornets pass out too.

00:05:46Some are trying to fly away, but the fog doesn't let them.

00:05:50All insects fall asleep.

00:05:52Someone used gas to stop this fight.

00:05:55And this someone is the bees' main ally.

00:05:58A human has come into the game.

00:06:01In thick protective suits, people picked up euthanized hornets from the ground.

00:06:06They put them in one basket and the bees in another.

00:06:09The collection of insects lasts for several hours.

00:06:11Then, the bees wake up in their hives unharmed.

00:06:15Hornets wake up in special containers.

00:06:17They're trapped, and now they can't hurt anyone.

00:06:21People are destroying hornets' nests all over the world.

00:06:24They won't allow them to multiply.

00:06:27Bees are responsible for the cycle of life in nature.

00:06:30They help many plants to reproduce, thanks to pollination.

00:06:34Bees serve as berries and fruits we eat.

00:06:36They take care of flowers that cows and other livestock feed on.

00:06:40Thanks to bees, we grow a lot of cotton.

00:06:43If the hornets destroy them, there will be a shortage of clothes made of this material.

00:06:47T-shirts, jeans, jackets… all this will be more expensive and then will disappear

00:06:53from the markets.

00:06:54Many products will lose their rich taste and useful properties.

00:06:58Animals and people won't get enough vitamins.

00:07:01Cows won't produce milk.

00:07:03There will be no cheese, sour cream, butter, and other food.

00:07:07You won't be able to order a juicy burger at the restaurant.

00:07:10Eggplants, hot peppers, kiwi, blueberries, cranberries, and much more will disappear

00:07:15from the counter.

00:07:17Whole species of animals and plants will stop existing.

00:07:20This will lead to other crises, not only in agriculture, but also in the global economy.

00:07:26Meanwhile, the number of hornets will be growing.

00:07:29There are almost no animals in the world to control them.

00:07:33If people don't do anything, everyone will have to wear thick protective suits to walk

00:07:37outside.

00:07:39Hornets will get into houses and cars, attack people and pets.

00:07:43One giant hornet can cause a lot of trouble.

00:07:46Its sting is one of the most dangerous and painful among all other insects.

00:07:50It's like a red-hot needle.

00:07:53When a hornet sticks it into an opponent, it injects the poison into the skin.

00:07:58This toxin dilates the walls of blood vessels.

00:08:01The area around the bite turns red.

00:08:03This can last for several hours or even days.

00:08:07The hornet is an aggressive creature.

00:08:09It can sting several times.

00:08:11Imagine what a group of these insects can do.

00:08:13To escape, you need to hide in bushes with dense foliage or jump into the water.

00:08:19After the hornets fly away, urgently contact the hospital.

00:08:23Hornets can make people's lives worse.

00:08:25It's important to fight them.

00:08:28Unfortunately, bees can't do this.

00:08:30They're absolutely defenseless.

00:08:32Humanity is aware of this danger and does everything to control the hornet's population.

00:08:38That's why giant hornets have no chances in this fight.

00:08:42Now every bee returns to its usual way of life.

00:08:46Pollination, nectar extraction, honey production in hives.

00:08:50The valley is blooming again.

00:08:52Bees can sleep peacefully.

00:08:55People monitor the situation and watch for giant hornets.

00:08:58If one enemy appears, it means there's a nest somewhere.

00:09:02Special services track down the insects and find nests under old trees and in pits.

00:09:11What was that on your arm?

00:09:12A bee.

00:09:13Great.

00:09:14Not exactly a pleasant feeling.

00:09:15Painful.

00:09:16Itchy.

00:09:17Annoying.

00:09:18Scary.

00:09:19We've all been there before.

00:09:20So that happens because the bee jabs its barbed stinger into your skin and releases some venom.

00:09:25The venom contains proteins that cause pain and can affect your immune system and skin

00:09:28cells.

00:09:29But that's nothing compared to what the bee has to go through.

00:09:32Poor little thing.

00:09:33You'll be fine after a few hours.

00:09:35But the bee?

00:09:36Not so much.

00:09:37Honey bees don't usually sting people unless they feel threatened or if you accidentally

00:09:40step on them.

00:09:41The problem is that after stinging you, the bee can't pull its barbed stinger out of your

00:09:45skin.

00:09:46The only way to get free is to leave the stinger behind.

00:09:49The stinger though, not just a sweet defense mechanism, it also contains part of the bee's

00:09:53digestive tract, nerves, and muscles that are, unfortunately, essential for the bee

00:09:58to function normally.

00:09:59So yep, after losing all that, this tiny creature doesn't survive.

00:10:03Yikes.

00:10:04Poor little bee.

00:10:06Apart from that, they're such cool animals.

00:10:08They have five eyes, two pairs of wings, and six legs.

00:10:12Bees have excellent survival instincts and they've been around for a really long time.

00:10:16130 million years and counting.

00:10:18Who knows what ancient species they've stung.

00:10:21Most bees in the hive are called worker bees, and the big cheese is called the queen.

00:10:25She lays around 2,000 eggs per day.

00:10:28Sound like a lot?

00:10:29Well, the average hive contains 50,000 bees, and they disappear after just one sting.

00:10:33I guess going through a painful and itchy experience doesn't actually sound that bad

00:10:37when you only have one bee on your arm.

00:10:40Imagine if you had the whole hive.

00:10:41It may seem like bees just aimlessly fly around or use their vision to decide where they go.

00:10:46But these cool insects are pretty organized and rely on a super complex transport system.

00:10:52Imagine planning a cross-country road trip, only this time, there are no roads.

00:10:55I can't even make it to the gym without my GPS.

00:10:58Or if I stop at a burger joint on the way there.

00:11:00But not bees.

00:11:01They're way cooler than us.

00:11:03They use bee lines.

00:11:04Well, I call them that.

00:11:06They're basically a series of insect pathways bees tend to follow through human towns or

00:11:10the countryside.

00:11:11These pathways link every existing wildlife area together.

00:11:14It's like a bee railway system.

00:11:17My favorite bee is the buff-tailed bumblebee.

00:11:20It has an oval-shaped body covered in dense hair and a brain the size of a poppy seed.

00:11:25Considering how small it is, that's really impressive.

00:11:27How smart are they?

00:11:29Scientists made an experiment where they trained a bunch of them to play bee soccer.

00:11:32They even learned how to score a goal in return for a sweet sugary treat.

00:11:36Unbelievable!

00:11:38These same bees have another amazing ability.

00:11:40They use their smelly footprints to distinguish between the scents of strangers, their own

00:11:44bee relatives.

00:11:45They can even recognize their own scent.

00:11:47Bumblebees, we know your dirty little secret.

00:11:49You have smelly feet.

00:11:51And then, there's the queen bee.

00:11:53She's unique in her colony, and her main task?

00:11:55Laying eggs.

00:11:56People often assume the queen is there to tell the other bees exactly what to do.

00:12:00Yeah, not really.

00:12:01She does have a certain influence, but even without her, the hive actually functions pretty

00:12:05well.

00:12:06Each bee has a job and knows its daily functions and tasks because of its instincts and the

00:12:11chemical signals it senses and uses.

00:12:13So, I guess no one needs to tell them how to… behave?

00:12:17Those chemical signals are their way of communicating.

00:12:19Oh, and they know how to shake it.

00:12:21They wiggle their bodies at specific angles for a certain amount of time.

00:12:24That's how they send messages to each other.

00:12:26If something happens to the queen bee and she doesn't survive, worker bees create

00:12:30a new one.

00:12:31Yep, they don't find one, but sort of raise a new one.

00:12:34They choose a young larva and feed the future, Her Majesty, a special food called royal jelly.

00:12:39That lucky larva can now grow into the new queen.

00:12:42Bees are fast.

00:12:43They can beat their wings almost 200 times a second.

00:12:46Those 8 push-ups I can do in a minute not sounding so impressive.

00:12:49Each bee produces around 1 teaspoon of honey in its lifetime.

00:12:52To produce 1 pound of honey, bees have to fly the equivalent of one whole time around

00:12:56the globe.

00:12:57These hardworking animals make around 100 million trips to about 200 million flowers

00:13:02to collect enough nectar for that pound of honey.

00:13:05Honey bees sleep 5 to 8 hours a day, and just like us, they rest at night.

00:13:09Their brains are pretty active when they're resting.

00:13:11Some scientists think they may be dreaming, also just like us.

00:13:15When winter rolls around, a lot of insects replace their body water with a special chemical

00:13:19called glycerol.

00:13:20It's a type of natural antifreeze that helps them stay alive in low temperatures.

00:13:24Bees though, they just huddle together in the hive to stay toasty warm.

00:13:28Alright enough about bees, let's whip round the animal kingdom looking for crazy facts.

00:13:33Bats could eat a thousand insects an hour if they were insanely hungry.

00:13:36They're the only mammal that can fly, and their bones are so thin, most of them can't

00:13:41even walk.

00:13:42Snails for the most part don't have ears on their heads, instead they have them all over

00:13:46their bodies.

00:13:48Snails can sleep for 3 years without waking up.

00:13:51Slugs have 4 noses, so they better avoid those stinky feet bumblebees.

00:13:55Butterflies are quite simple and practical animals that taste with their feet and only

00:13:59feed on liquids.

00:14:01They're cold blooded, so if it gets below 55 degrees they can't fly, look for food, or

00:14:05escape a sticky situation.

00:14:07Their main defense tactic is camouflage, works pretty well, until it gets cold.

00:14:12The opposite strategy is having vibrant, colorful patterns that let everyone know where you

00:14:16are.

00:14:17Colorful insects are often toxic, so birds and bigger insects tend to leave them alone.

00:14:22Wasps recognize their relatives by identifying unique facial patterns.

00:14:27Ants don't have lungs, instead they breathe through small holes all over their bodies.

00:14:31Also, they almost never sleep, but they do love to nap.

00:14:35Ants are incredibly strong and can carry more than 50 times their own weight.

00:14:38If you were that strong, you'd be able to carry an adult elephant, you know, like if

00:14:42it's stepping on your toe and you want to get it off you?

00:14:45For every human, there are more than a million ants, and over 200 million insects.

00:14:49Luckily, they're smaller than us, if they weren't, we'd be the ants.

00:14:54You can hypnotize a frog if you place it on its back and gently stroke its stomach with

00:14:58your fingers.

00:14:59What if that worked on humans?

00:15:00Hey, wanna hang out?

00:15:02I know a sloth does.

00:15:04Its weird biology allows it to spend most of its life just hanging upside down from

00:15:08a tree.

00:15:09A sloth is so slow, it takes around a month to totally digest food.

00:15:13Rhinos have horns made out of the same stuff as hair.

00:15:16Scientists trained pigeons to be able to tell the difference between famous artists Claude

00:15:20Monet and Pablo Picasso.

00:15:22Okay, wait, even pigeons are smarter than me now?

00:15:26Just when you think pandas can't get any cuter, check this out.

00:15:29When they're born, pandas weigh around 4 ounces and are smaller than a mouse.

00:15:33Animals that have a super-fast metabolism inside a small body, like squirrels do, see

00:15:37in slow motion.

00:15:38They evolved this feature to be able to escape bigger animals.

00:15:41That's cool, when you think about it, it really makes them powerful.

00:15:45Squirrels usually run away from their enemies by scampering off in a zigzag pattern, because?

00:15:50No idea.

00:15:51Sorry, people.

00:15:52They tend to bury their food in many different places.

00:15:54Since it's impossible to keep an eye on all their hiding spots, other animals like to

00:15:58sneak over and steal their goods.

00:16:00That's why squirrels sometimes only pretend to bury their food somewhere, to throw off

00:16:04any potential thieves.

00:16:06Oh, how nutty of them.

00:16:07An ostrich has a brain smaller than its eye, but it has really strong legs.

00:16:12It can run faster than a horse.

00:16:15Flamingos only eat when their heads are turned upside down.

00:16:18You know, scorpions are interesting little creatures.

00:16:20Six legs, two claws, and a powerful stinger.

00:16:23Now, what if humans also wore exoskeletons to protect themselves?

00:16:28So an exoskeleton's mainly made up of chitin, which is a complex material found in insects

00:16:33and reptiles.

00:16:35Thanks to their exoskeletons, these tiny creatures can defend themselves and perform acts of

00:16:40superhuman strength.

00:16:42If you wore a scorpion exoskeleton, you'd be able to climb up any building you wanted.

00:16:48With massive claws in the front, it would be easy to grab hold of things and even cut

00:16:52through them.

00:16:53Might be hard to open a bag of chips, though.

00:16:56But at night, you'd have problems – UV rays.

00:16:59They wouldn't hurt you or cut through you or anything, but you'd definitely glow in

00:17:03the dark.

00:17:04It's not exactly ideal for sneaking up on someone.

00:17:07A scorpion's tail is venomous and packs a nasty sting.

00:17:11You could use it to sting anyone in your way, plus it's long enough that you could defend

00:17:16yourself from a safe distance.

00:17:19Scorpions live all over the world in some of the harshest environments, from freezing

00:17:23icy landscapes to scorching hot deserts.

00:17:26If it freezes, a scorpion can even thaw itself out under the sun.

00:17:31This next creature also has two claws and six legs, but it doesn't have a stinger.

00:17:36It's the mighty crab.

00:17:38Its shell is a lot more powerful than a scorpion's, and it's surprisingly quick.

00:17:42So you'd be seriously powerful in one of those.

00:17:45The downside is you'd only be able to walk sideways.

00:17:49And you'd be delicious to someone like me.

00:17:52There are almost 5,000 species of crab all over the world, each with special skills.

00:17:58In a crab costume, you'd definitely be a master digger.

00:18:01Sure, you'd be doing it sideways, but those legs and claws can get the job done.

00:18:07If there were crab-inspired bodysuits, they'd most likely be made for digging.

00:18:11You could even work underwater.

00:18:13You'd be agile, strong, and you'd look awesome.

00:18:17Humans in ant suits would dominate any construction site.

00:18:21Ants live in colonies around most of the world and rely on strength and numbers.

00:18:26But that doesn't mean each little ant's weak or anything.

00:18:29Just the opposite.

00:18:30There are actually already exoskeleton suits out there to help humans do some heavy lifting.

00:18:36But to use the actual strength of an ant would be a game-changer.

00:18:40An ant can lift around 1,000 times its own weight.

00:18:44In a group, they can drag a bird across a field without breaking a sweat.

00:18:48What's even crazier is that they can carry things while they're climbing straight up

00:18:52a wall.

00:18:53Or even upside down.

00:18:55Imagine a group of humans dragging a jet fighter up the side of the Empire State Building.

00:19:00There wouldn't be any need for bulldozers or cranes anymore.

00:19:04Just strap into an ant suit and get her done.

00:19:07Buildings could be inspired by those huge underground ant colonies.

00:19:11Ants are amazing at making tunnels.

00:19:14Imagine wearing a bodysuit that flies through the air like a stealth craft.

00:19:18If you wore a hornet suit, you'd have it made.

00:19:21They have a tough exoskeleton that's surprisingly light and easy to maneuver.

00:19:26Picture a fleet of strong flying acrobats.

00:19:29Oh, and don't forget the stinger.

00:19:32Most people think of hornets as pests, but they're not.

00:19:35They do a lot of good for the ecosystem, like eating up those pesky mosquitoes.

00:19:40Having a hornet suit would be essential for any kind of undercover work.

00:19:44Not so much for office work.

00:19:45A strong, aerodynamic bodysuit with a powerful stinger?

00:19:49Sign me up!

00:19:51An armadillo uses keratin to make its bodysuit.

00:19:54You know, the stuff your hair and nails are made of?

00:19:57What makes it unique is that it's foldable and durable at the same time.

00:20:01It's made up of hexagon-shaped plates that go all over its back.

00:20:06When there's danger around, it can roll up into a ball.

00:20:10Scientists are studying how to make durable bending glass just like the armadillo's

00:20:14body plates.

00:20:15Humans wouldn't be 100% protected with this thing on, but they'd be able to withstand

00:20:20pretty much anything.

00:20:22You could jump out of a plane, no parachute, land on a rooftop, brush it off, roll off

00:20:27the edge, and land safely on a nearby car.

00:20:30All while being chased by tricked-out cars and helicopters.

00:20:33Nah, I've been streaming too many movies.

00:20:37Being one of the slowest animals on Earth does come with an advantage.

00:20:41You got a heavy shell on you 24-7 for protection.

00:20:44Just like armadillos, tortoise shells are made of keratin.

00:20:48What's sweet about its shell is that it grows with the tortoise.

00:20:52Crabs and other shelled animals have to keep replacing theirs as they outgrow them.

00:20:57Humans would be almost invincible if they wore tortoise suits, but they'd be insanely

00:21:01slow and draw a lot of attention.

00:21:03Still, if something goes down, you could just hide in your shell and wait it out.

00:21:09Hopping around from place to place would be pretty sweet, but what about flying?

00:21:13Grasshoppers can do both.

00:21:15They have a set of wings they tuck in behind them, which they unleash after their epic

00:21:20take-off jump.

00:21:21Oh, and they come in all shapes and sizes – great for camouflage!

00:21:26A grasshopper can jump around 10 inches high and 3 feet long.

00:21:30Far?

00:21:31Out?

00:21:32That far!

00:21:33Anyway, it's all thanks to its back legs.

00:21:37Grasshoppers basically catapult themselves when they feel threatened or when they see

00:21:40something delicious.

00:21:42If you had a grasshopper suit, you'd be able to jump a whole football field in one

00:21:46go.

00:21:47You can forget about being stuck in traffic!

00:21:50It might not be the most powerful armor, but with those jumping skills and landing skills,

00:21:55getting your weekend shopping done would be a breeze!

00:21:58Or you could be the world's coolest pizza delivery person!

00:22:01Just imagine the tips!

00:22:04The biggest animal on this list doesn't really have an exoskeleton, but it does have

00:22:08a thick, thick skin.

00:22:10This massive beast is one of the most powerful mammals on Earth, and it comes with a strong

00:22:15horn near its nose for protection.

00:22:17Any guesses?

00:22:18It might look scary, but that humongous rhino is an herbivore – it's not gonna eat you!

00:22:24But rhinos do attack when they feel provoked, so keep your distance.

00:22:28Their thick skin makes them look like a tank, and it keeps them nice and warm.

00:22:33With your rhino suit on, you'd have a monster advantage over the average human.

00:22:37The thick skin suit would be really useful for extreme weather conditions, cold or hot.

00:22:42And a horn on the top of your head would send a pretty powerful message.

00:22:46And it's not just beep-beep!

00:22:50Jaws that look like antlers?

00:22:51Six legs?

00:22:52Meet the stag beetle.

00:22:54Its oversized jaws are used for impressing its friends, and sometimes for a little wrestling.

00:22:59But don't worry, these fearsome jaws aren't strong enough to hurt you.

00:23:03A human stag beetle suit would be pretty weird if you saw one walking down the street.

00:23:08But who knows what people will be into in 10-20 years?

00:23:12Maybe this'll be the future of wrestling!

00:23:15This reptile has the toughest skin of its kind.

00:23:18Crocodiles are fearsome animals, virtually unchanged since the days of the dinosaurs.

00:23:23Our modern-day croc is still top of the food chain, with scales on its back and a very

00:23:28soft underbelly.

00:23:30Its scales are made from some of the most durable materials out there.

00:23:33And don't forget that powerful jaw!

00:23:36It can crush watermelons like chewing gum!

00:23:38A human croc suit would be fast, strong, but mostly limited to hanging around lakes and

00:23:44rivers.

00:23:45It'd be a great thing to be wearing during a game of hide-and-seek, though.

00:23:48You're it!

00:23:50This last creature takes the grand prize – toughest exoskeleton ever!

00:23:56It's smaller than a rhino for sure.

00:23:58Presenting the Iron-Clad Beetle.

00:24:00Even the name makes people's knees weak.

00:24:03This beetle has interlocking wing covers that make it twice as strong as it should be.

00:24:07But get this – it doesn't even fly!

00:24:09Yeah, it doesn't need to escape from danger.

00:24:12Whatever you throw at it, it can't be hurt, dented, or even crushed.

00:24:16Not even by a car!

00:24:18These beetles can live up to 2 years – way longer than other beetles who only stick around

00:24:23for a couple of weeks or months.

00:24:25A human suit based on the Iron-Clad Beetle?

00:24:28Wow, that name gets me every time.

00:24:30It'd probably be resistant to just about any collision.

00:24:34Walking through moving traffic would be like strolling in the park on a warm afternoon.

00:24:39This suit would be perfect for deep-sea exploration since it's resistant to pressure.

00:24:44That'd make it excellent for outer space adventures too!

00:24:47Mosquitoes, bedbugs, fleas, beetles, gadflies – millions of insects out there can't

00:24:54wait to feast on the most delicious dessert – you.

00:24:57Especially if it's warm outside and you sweat a little.

00:25:01The good news is that not many bugs want to eat you.

00:25:04It's estimated that there are about 10 million species of insects in the world, and only

00:25:1014,000 of them feed on your vital fluid.

00:25:13A few hundred among this group regularly bite people.

00:25:16Um, okay, yeah, it's still too many.

00:25:20But it wasn't always like that.

00:25:22In the distant past, insects didn't dare to attack huge animals for food.

00:25:26They developed their ability to feed on blood from 200 to 65 million years ago.

00:25:32And there are several theories why this happened.

00:25:34Imagine small beetles and insects living in the nest of some flying dinosaur or a giant

00:25:40ancient bird.

00:25:41They feed on bird secretions, rotten grass, leaves, or mushrooms.

00:25:47Then a piece of skin or a feather of an animal falls on their table.

00:25:51Insects taste it, and they like it.

00:25:54Then a dinosaur arrives, and the beetles sense a familiar smell.

00:25:58They climb on its skin and bite it.

00:26:00Or they accidentally fall on an open sore of a bird and taste it.

00:26:04For insects, this would be the most delicious thing they had ever eaten.

00:26:09Yeah, I agree, it's a pretty low bar.

00:26:12Now other insects have a long, thin feeding tube called a proboscis.

00:26:16They use it to feed on plant sap or other smaller insects.

00:26:20And now, one of these beetles sits on a wounded mammal and accidentally bites it.

00:26:26The beetle's body already has the right enzyme capable of digesting blood.

00:26:30So from that moment on, the beetle doesn't want to eat anything other than red nectar.

00:26:36The beetle bears offspring, and it takes over the ability to feed on blood.

00:26:41Imagine you've been eating grass and leaves all your life.

00:26:44And then you try some sweet banana pudding.

00:26:47You wouldn't want to go back to eating good old grass now.

00:26:50You'd always want dessert.

00:26:52Insects had the same feeling when they tasted nutritious blood.

00:26:56Yum-bo!

00:26:57One of the coolest theories says the thirst for blood in insects was caused by microbes.

00:27:03Blood isn't an ideal food for beetles.

00:27:05It doesn't have enough vitamins or nutrients for them.

00:27:08That's why a whole ecosystem of microorganisms had to form inside their intestines.

00:27:14These bacteria can synthesize some essential vitamins with the help of blood.

00:27:18These bacteria won't survive if they stop feeding on that red fluid.

00:27:23And when these bacteria disappear, insects have problems with development and reproduction.

00:27:29It's impossible to name the exact reason since the transition from plant food to animal food

00:27:34happened a very long time ago.

00:27:37Since then, evolution has created a variety of ways to extract blood.

00:27:41The most famous blood-dependent species are, of course, mosquitoes.

00:27:46The female mosquitoes need blood to produce eggs.

00:27:49When mosquitoes fly, they feel the heat, carbon dioxide, and lactic acid in the air.

00:27:55These smells attract the mosquitoes, so they fly to their source – an animal or a human.

00:28:01Then the mosquito lands on its prey and inserts its proboscis into the skin.

00:28:06At the same time, it secretes saliva to prevent clotting.

00:28:10The unpleasant skin sensation you get after the bite is an allergic reaction of your body

00:28:15to the mosquito saliva.

00:28:17Then the female produces eggs and leaves the larva in stagnant water.

00:28:21It could be a pond, a drain, or an outdoor pool.

00:28:25Small mosquitoes feed on organic substances in the water, then grow up and go on their

00:28:30first hunt.

00:28:32Black flies also feed on blood, but they don't do it as carefully as mosquitoes.

00:28:37The female black fly lands on the prey, uses its sharp jaws to cut the skin, and devours

00:28:43its lunch.

00:28:44Fortunately, they don't bother people too much.

00:28:47Their main target is livestock and wild animals.

00:28:50Horse flies and deer flies are the real human enemies.

00:28:53Their bite is quite painful.

00:28:56Ordinary flies that live on the street and inside human houses are super annoying and

00:29:01they can feast on your skin without even biting you.

00:29:04Everything they need from you lies on the surface.

00:29:07You secrete sweat, proteins, carbs, salts, sugar, and other chemicals that the fly collects

00:29:13with its proboscis.

00:29:15And of course, it hardly understands that you're a living being and don't want to

00:29:19share your food with it.

00:29:20That's why a fly isn't afraid of you.

00:29:24You probably noticed that some people get bitten by insects more often than others.

00:29:28You could be going for a walk in the park, and they get all over you.

00:29:32But your friend walking right next to you wouldn't feel anything.

00:29:35It just means you're a sweetie.

00:29:38Scientists used to believe that some people actually just don't feel it when they get

00:29:42bitten.

00:29:43The human body doesn't have such a strong reaction to mosquito saliva.

00:29:46But recent studies have shown the number of bites depends on genetics and many other factors.

00:29:52Around 10-20% of people are just more attractive to predatory insects.

00:29:57How lucky or unlucky are they?

00:30:00Mosquitoes use a variety of senses to choose the perfect prey.

00:30:04They have carbon dioxide and humidity sensors.

00:30:07They also distinguish the odors of hundreds of different chemicals released by humans.

00:30:12Each smell has a specific meaning for different types of mosquitoes.

00:30:17There are thousands of nuances and shades of odors that can attract some mosquitoes

00:30:21and repel others.

00:30:23The mosquitoes that are more aggressive like things that ordinary mosquitoes can't smell.

00:30:28Some mosquitoes go for your legs, others like your neck.

00:30:32The food and drinks you consume play an important role in that too.

00:30:36They change the smell of your skin, the thickness of the skin, the amount of heat released,

00:30:41shades of color, and your blood type.

00:30:43All of that matters to insects.

00:30:46But there's something that attracts almost all insects.

00:30:49It's the smell of sweat.

00:30:51The dirtier you are, the more attractive you are to them.

00:30:55The unpleasant smell of sweat is created by millions of bacteria gathered on your skin.

00:31:00They attract mosquitoes.

00:31:02Some species like fresh sweat.

00:31:05Others prefer stale sweat with an unpleasant aroma.

00:31:09If you're clean, you'll become invisible to most of the little flying monsters.

00:31:14The smell also depends on your genetic features.

00:31:17The structure of your DNA directly affects the smells you release.

00:31:22That's why you can say that some people are sweeter when it comes to mosquito tastes.

00:31:26But mosquito bites are really nothing compared to those of fire ants.

00:31:31When it munches on your skin, it feels like it's on fire.

00:31:35These ants are especially dangerous for people with allergies.

00:31:38Huss caterpillar is a beautifully vicious creature.

00:31:42It doesn't need to bite you to hurt you.

00:31:44This insect, also known as the southern flannel moth, is covered with thick fur hiding many

00:31:49poisonous thorns.

00:31:51A small prick with these spines, and you need medical assistance immediately.

00:31:56The Asian giant hornet is one of the most dangerous and painful insect bites of all.

00:32:02One hornet can be the size of a person's thumb, and its sting resembles a real needle.

00:32:07It's almost three times the size of a bee.

00:32:11These aggressive creatures can bite through clothes and even beekeepers' outfits.

00:32:15They attack in a huge swarm and can cause serious trouble to any animal.

00:32:20To fight them, people wear thick protective suits that look like spacesuits.

00:32:25But the main danger is that hornets attack beehives and greatly reduce the bee population.

00:32:30This can lead to a catastrophe on a planetary scale.

00:32:34Our planet and humanity need bees, not only because they produce honey.

00:32:39Bees pollinate flowers and plants.

00:32:42About a third of the world's food production would be impossible without bees.

00:32:47Cows eat vegetation that bees pollinate, and if all bees disappeared, it would greatly

00:32:51affect not only the health of cows, but all other cattle as well.

00:32:56A lot of fruits and berries would lose their rich taste if the bees stopped serving them.

00:33:01We get most of the cotton on the planet thanks to bees as pollinators.

00:33:05There would be a shortage of jeans and other clothes if the bees disappeared.

00:33:09The taste of many products would deteriorate, and the food would lose its useful properties.

00:33:15Whole species of flowers would disappear from the face of our planet.

00:33:19Humanity would have a really difficult time without bees.

00:33:22That would be a disaster, and that's another reason why giant hornets are so dangerous

00:33:28And they gotta go, if you ask me.

00:33:36So you're at home, enjoying your evening tea under a warm blanket, when all of a sudden

00:33:41you see a huge, no, ENORMOUS mosquito.

00:33:45Its long and gangly legs have a span of your palm, and it clumsily bumps into all the obstacles

00:33:51it meets.

00:33:52Despite its awkward appearance, it's still terrifying.

00:33:55What if it carries malaria?

00:33:57What if it eats you alive in your sleep?

00:33:59Slowly, not to draw the monster's attention to yourself, you get out from your soft chair

00:34:05and run for it into the bathroom, lock yourself in there, and open the browser on your phone.

00:34:11After a few seconds, you draw a ragged breath of relief.

00:34:15Turns out it's just a crane fly, not a mosquito at all.

00:34:19It might look like a ferocious beast, but it's actually peaceful and even defenseless.

00:34:24Many crane flies don't even have mouths, so they don't eat at all, and those that

00:34:29have a mouthpiece will only munch on sweet flower nectar.

00:34:34Crane flies are really clumsy in the air.

00:34:36Their rather short wings are no match for their huge bodies and long legs, so they're

00:34:41slow and it's easy to catch them.

00:34:44Birds and frogs, as well as bats and cats love them as a treat.

00:34:48The only way they can avoid being eaten is by losing a limb.

00:34:52Their legs easily break off even when nothing touches them.

00:34:57And if you're still unconvinced not to scram and set your house on fire when you see one,

00:35:02consider this.

00:35:03Crane flies can tell you if the water pool you're about to swim in is of good quality.

00:35:08If you see these bugs on or above the water, you're good to go.

00:35:12Even more, fishers often make their bait look like the crane fly larvae.

00:35:17This makes it more appetizing for the fish!

00:35:21But while Googling, you get engrossed with reading up on some other weird and crazy bugs.

00:35:27For example, here's the human-faced stink bug.

00:35:30Nah, they don't really stink, at least for humans.

00:35:33They give off pheromones that attract other stink bugs, letting them know there's food

00:35:37nearby.

00:35:39The most peculiar feature of it is in the name.

00:35:42A man-faced stink bug has a face on its back with three black dots drawn in red.

00:35:48The vibrant color of its back warns predators that the bug isn't tasty or even poisonous,

00:35:54while the black eyes draw attention from them to the vulnerable head.

00:36:00Saddleback caterpillar's name is also quite telling.

00:36:02It looks like some creature from another planet with a bright green saddle over its back.

00:36:08And the saddle is, sadly, the only safe part of the thing to touch.

00:36:12The spines you see all over the rest of its body are sharp and highly poisonous.

00:36:17If you want to give it a friendly tap on the back, make sure you don't touch anything

00:36:21else.

00:36:22Well, well, we have a titan beetle next!

00:36:26Meet the largest beetle in the whole world!

00:36:28It can grow as long as your entire palm, complete with fingers!

00:36:33Seeing one in the wild can be a shocking experience, especially if it flies right in your face!

00:36:38But don't fret, thankfully, this giant is placid and won't bite you if you don't

00:36:44mean it harm.

00:36:45Still, if you make it angry, never let its mandibles touch you!

00:36:50The bug will hiss and bite, and what such snap can crack a pencil in half?

00:36:55What's interesting, an adult titan beetle doesn't feed at all.

00:36:59It doesn't need food to survive.

00:37:01As a larva, it gets enough energy to keep it well-nourished even when grown up.

00:37:05Ooh, I love that ability!

00:37:08An even more menacing-looking bug is a giant weeda.

00:37:12Living in New Zealand, these cricket-like creatures look like someone forgot to lock

00:37:16the portal to the infernal.

00:37:18A massive, beefy body with six thorny legs, long alien-looking antennae, and big mandibles

00:37:25that just might cut steel!

00:37:27Well, in fact, these giant insects are quite peaceful and won't bite unless provoked.

00:37:34And even if they do, it's not as bad as you might think.

00:37:37There are videos with weedas biting hands of people holding them and doing no harm at

00:37:42all.

00:37:43So don't let it scare you, even though such an insect might weigh more than a full-fledged

00:37:47sparrow.

00:37:49Atlas moths look like they have three heads, two of which are serpents.

00:37:54These pretty nocturnal fliers have strange shapes on the tips of their wings that look

00:37:58like snake heads.

00:37:59This seems to be their mode of defense from predators.

00:38:02And that's also why they're sometimes called cobra moths.

00:38:07In Southeast Asia and India, where they normally dwell, atlas moths are often found on butterfly

00:38:13farms producing silk.

00:38:15And that's some sight!

00:38:16The wingspan of one such moth can reach 10 inches!

00:38:20That's larger than your hand!

00:38:22Peacock spiders are perhaps the cutest arachnids in the world, second maybe only to their jumping

00:38:28cousins.

00:38:29They're so tiny, you probably wouldn't even notice one scrambling through your kitchen.

00:38:34But if you get a chance to take a closer look, do it!

00:38:38Peacock spiders are beautiful.

00:38:40They have large beady eyes, a shiny blue and red coat, and cute fuzz on their body and

00:38:45legs.

00:38:46And their mating dance is something else entirely.

00:38:49Too bad they only live in Australia.

00:38:52Another moth on the list, the hummingbird moth.

00:38:56Remember the atlas one, how huge it was?

00:38:58Well, this one's as big as a hummingbird and holds much more resemblance to its namesake

00:39:03than that.

00:39:04The speed at which it flutters its wings, the long tongue to drink flower nectar, and

00:39:10even the sound it makes when flying – all of it makes you wonder if it's really a

00:39:14moth after all.

00:39:15Of course, the fuzzy critter is absolutely safe, and you should consider yourself lucky

00:39:20if you ever see one!

00:39:23Long-horned orb-weaver spider is one of the most unusual arachnids in the world.

00:39:28It's just your regular spider in all respects, but for some reason, it boasts two long curved

00:39:34horns on its back.

00:39:36The back itself is bright orange to ward off predators, red means danger.

00:39:41But scientists are still unsure why this spider needs those prongs, so there's a web of

00:39:47mystery for you.

00:39:49The soft rustling of leaves underneath, a pile of them slightly moving, and a big mighty

00:39:55horn shows up.

00:39:57It's the Hercules beetle, one of the largest beetles on the planet.

00:40:01Almost half of its size comes from that horn on its head.

00:40:04Thanks to this wonderful appendage, you know exactly it's a male.

00:40:09Females don't have it at all.

00:40:12Yet the name comes not only from the horn, but from the amazing ability of this giant

00:40:16to haul extremely heavy loads.

00:40:19Its strength is second only to dung beetles – a Hercules can carry as much as 850 times

00:40:25its own weight!

00:40:27If you ever see a bug with five heads wearing a pointy cap, no, you're not on another

00:40:33planet.

00:40:34It's a Brazilian treehopper.

00:40:36Straight from a sci-fi movie and onto your screens here, this insect is a real mystery.

00:40:41It's small and secretive, and much is still unknown about it.

00:40:46No one knows why exactly the treehoppers have these fuzzy balls on their heads.

00:40:51But they've only got one head, after all.

00:40:54That much is certain.

00:40:56Going for a swim in a freshwater pond somewhere in the African tropics.

00:41:00Watch your toes, you can get a giant water bug hunting them!

00:41:04It's a predatory bug and the largest of its kind.

00:41:08With those huge pincers, it's no wonder it's commonly known as an alligator flea

00:41:13and a toe-biter.

00:41:15The bite of this water-dwelling monster is really quite powerful.

00:41:19It grabs its prey with the front legs and then slowly munches on it.

00:41:23And when I say it's a predator, I mean it.

00:41:26Giant water bugs' favorite food is fish and amphibians.

00:41:32Despite their name, scorpion flies aren't related to scorpions.

00:41:36They get this moniker thanks to their tails, which look a lot like the notorious arachnids.

00:41:41Seeing a flying scorpion is a daunting sight at best, but fear not, these critters are

00:41:46small and gentle, and they can't even bite you.

00:41:50Only the males have such a tail, and they use it to attract females.

00:41:57What do you imagine when you hear the words walking stick?

00:42:00Certainly not a bug, but that's exactly what it is.

00:42:03Look at this twig and try to guess.

00:42:06Is there something alive on it or not?

00:42:08Yes and no.

00:42:10This twig is not a twig at all.

00:42:12It is a walking stick.

00:42:15These insects have developed a fascinating camouflage.

00:42:18They're long and unassuming, able to stay still for hours on end, which makes them look

00:42:24like dry twigs.

00:42:25But as soon as you touch one, it scrambles away on its gangly legs.

00:42:31Thanks to their appearance, predatory birds often miss walking sticks and the dense foliage.

00:42:36And their Australian kin give off a pleasant scent, something like peanut butter.

00:42:41Yum!

00:42:43A wildlife administrator at an airport can escort a deer off the airfield.

00:42:47They can keep a family of ducks away from the airport's wet pond.

00:42:51They can even shoo off wayward raccoons hiding in terminal buildings.

00:42:54What they can't do is deal with honeybees.

00:42:58In August 2012, hundreds of thousands of honeybees swarmed the body of a Delta plane heading

00:43:03to New York City.

00:43:04It happened when the crew was preparing to fuel the aircraft and load the luggage.

00:43:08It was time for master beekeeper Stephen Rapaskey to come into play.

00:43:12At that time, it was already the fourth swarm the airport had to deal with in the past few

00:43:16months.

00:43:17And when in May 2012, more than 15,000 bees covered a light on taxiway C, it caused a

00:43:24serious flight delay.

00:43:25That's when the airport's wildlife administrator started to Google nearby beekeepers.

00:43:29Luckily, he came across Mr. Rapaskey, who was later employed as a contractor.

00:43:35An ostrich babysitter's job is mostly stopping little ostriches from running off or pecking

00:43:39at one another.

00:43:41These specialists spend hours on end sitting and observing their charges.

00:43:46This work is far from simple and relaxing, though.

00:43:49Ostriches are known for being territorial and quick to anger.

00:43:52If they feel threatened, they can even charge at a person.

00:43:55An ostrich babysitter can never leave their guard down.

00:43:58Otherwise, one of the birds they're responsible for will immediately get into trouble.

00:44:04A legal bank robber is also called a penetration tester.

00:44:07These people test if banks have an appropriate level of security.

00:44:11In the past, the profession was rather straightforward.

00:44:13You had to literally break into a bank.

00:44:16These days, fake robbers still exist.

00:44:19But there are also specialists who check computer security and deal with identity theft.

00:44:23They can even impersonate police officers and try to install surveillance cameras in

00:44:27the vaults.

00:44:30A scuba diving pizza delivery person works in an underwater hotel in Florida.

00:44:34This specialist dons their scuba gear and sets off on the mission.

00:44:38They supply hotel guests with freshly baked hot pizza carried through the sea in a watertight

00:44:42container.

00:44:46A pet food tester's job is a combination of a researcher and a tester.

00:44:50It's often someone with a doctoral degree.

00:44:52This specialist doesn't taste pet food.

00:44:55They test it.

00:44:57They mainly analyze the food's nutritional value.

00:44:59They write all kinds of reports and look for ways to improve the already existing foods.

00:45:04Before actually trying the food, a tester smells it.

00:45:07Not every pet owner will want their kitchen to reek of fish.

00:45:10After that, it's time for tasting food.

00:45:13Testers are supposed to evaluate its texture, consistency, and flavor.

00:45:17Once it's done and noted down, they spit out the food.

00:45:21A nail polish namer looks at a newly invented color of nail polish and tries to describe

00:45:26it in a couple of words.

00:45:28They either think of what it looks like or how it makes them feel.

00:45:33Not so long ago, NASA and the European Space Agency needed professional sleepers.

00:45:38These organizations were ready to pay each of the 24 volunteers aged between 24 and 55

00:45:44more than $18,000.

00:45:47These people were supposed to spend 60 days lying in beds.

00:45:50They could read, play games on their phones, watch their favorite series.

00:45:54The only thing they couldn't do was get up.

00:45:56Plus, their beds had to be angled down toward the head end by 6 degrees.

00:46:01This way, scientists wanted to check how artificial gravity would affect the human body.

00:46:07One of the benefits of a golf ball diver's profession is working outdoors at all times.

00:46:12This person is in charge of collecting golf balls from the bottom of ponds on golf courses.

00:46:16It sounds like a simple and exciting job, but most of these ponds aren't taken care

00:46:20of regularly.

00:46:21That's why divers have to search for golf balls in muddy water with loads of algae.

00:46:26Sometimes, they even have to deal with snakes.

00:46:30A coconut safety engineer protects people from getting hit on their heads by fallen

00:46:34coconuts.

00:46:35The consequences of such accidents are usually extremely unpleasant.

00:46:40That's why a coconut specialist climbs palm trees, often towering up to 60 feet high,

00:46:44and picks ripened coconuts.

00:46:46This way, they don't fall down on the heads of unsuspecting tourists.

00:46:50A potato chip sorter searches for clumped or overcooked chips when those are moving

00:46:54down the assembly line.

00:46:56Once they see a piece that looks off, they immediately get rid of it.

00:47:01Amsterdam is one of the most bicycle-friendly cities in the world, and it's probably no

00:47:05wonder that hundreds of bicycles end up in the city's countless canals.

00:47:09Bicycle fishers pull more than 14,000 bikes out of the waterways every year.

00:47:14Most of these two-wheelers are old and rusty.

00:47:16A drying paint watcher is usually hired by a company to attentively observe the paint

00:47:21as it dries.

00:47:22They need to pay attention to any changes in the paint's color and texture.

00:47:26A skilled watcher should be able to do it both on the wall and under a microscope.

00:47:31This process helps to figure out how durable the paint is and make sure it won't fall

00:47:35off at the slightest touch.

00:47:37A drying paint watcher may also spend days painting sheets of cardboard.

00:47:41This helps to check new paint mixes, for example, how long it takes them to dry completely.

00:47:47A wrinkle chaser makes sure there are no unwanted wrinkles on shoes when they leave the factory.

00:47:52Their job description includes, for example, ironing wrinkles from shoes and shoe parts.

00:47:57To do that, a wrinkle chaser uses either a heated iron or a hot air blower.

00:48:02Sometimes it can be a special all-shaped device.

00:48:06Paper towels have either a light pleasant aroma or no smell at all.

00:48:09A paper towel sniffer is the very person who makes sure of that.

00:48:13These specialists are hired by manufacturers who want to confirm their production doesn't

00:48:17have an undesirable stench.

00:48:19Unfortunately, it's almost impossible to land this position.

00:48:23It's likely to be the tiniest job niche out there.

00:48:26It's a waterslide tester's responsibility to check whether waterslides in hotels and

00:48:30water parks are both fun and safe.

00:48:33Let's say you get yourself this job and start working as a waterslide tester for a big travel

00:48:38agency or a hotel chain.

00:48:40Then you'll spend most of your time on the move, traveling from one water park to another.

00:48:45Once you're there, you change into some swimming outfit and make it to the pool.

00:48:48You're supposed to take tons of trips down the slide.

00:48:51Pay attention to how fast you get down, how much water the slide uses, and how exciting

00:48:55the entire experience is.

00:48:59Sunglasses doctors work at large tropical resorts.

00:49:01Their main tasks are cleaning sunglass lenses, tightening screws, and solving all kinds of

00:49:07eyewear-related crises guests might have.

00:49:09A sunglasses doctor usually patrols the hotel territory in the afternoon, wearing a utility

00:49:15belt with special tools.

00:49:18A furniture tester is a person who tests beds, including pillows and mattresses.

00:49:23Hotels and other companies hire these people to literally sleep at work.

00:49:27Even though it sounds like a dream job, a good bed tester has to know a lot.

00:49:31For example, how to check if a mattress has dips by laying on it in a special manner,

00:49:36or how to figure out whether the edges of a bed are sturdy enough to sit on.

00:49:40A chewing gum chewer, also called a gumologist, spends their days chewing gum.

00:49:45They test its texture and flavor.

00:49:47They also need to describe how their mouth feels during and after the chewing process.

00:49:52Some days, a gum chewer has to blow lots of bubbles, depending on the stage of the project.

00:49:57But their main responsibility is researching and creating new flavors.

00:50:02If you don't have time to stand in line or you find this process boring and tiring, you

00:50:07can hire a professional line stander.

00:50:09For a fee, they'll replace you when you have a line for hours on end.

00:50:13For example, to get a sample sales item or a newly launched product.

00:50:18People with pretty hands, beautiful fingers, or nice feet can become body part models.

00:50:23Such professionals are often very well paid.

00:50:26They take part in photo shoots that advertise and promote particular products, for example,

00:50:30jewelry, nail polish, or hand cream.

00:50:34Dog surfing coaches are sometimes hired by hotels to teach guest dogs how to surf.

00:50:39It turns out pooches often learn to surf much faster than their humans.

00:50:44Marmite tasters have to taste every batch of the famous food spread made from yeast

00:50:48extract.

00:50:49They check whether the product has the necessary texture and consistency.

00:50:54They also pay attention if its taste is within the range of acceptable marmite flavors.

00:51:01Bzzzzz.

00:51:05The sound you hear when bees aren't around doesn't come from their mouths.

00:51:09You hear it because they're beating their wings while flying really fast.

00:51:14When they're in the air, their wings make vibrations the human ear recognizes as buzzing.

00:51:20It's especially loud when it comes to smaller insects.

00:51:23Bigger bees have slower wing beats, which means the pitch of the buzzing gets lower.

00:51:29Insects buzz to get pollen off the flower as they move their bodies and wings.

00:51:33The pollen then attaches to the bee.

00:51:35It flies towards the next flower and deposits the pollen there.

00:51:38This process is called pollination.

00:51:42You will also hear buzzing when they're defending their hives or themselves, especially

00:51:46if you get too close to a bee in its natural habitat.

00:51:49This buzzing sound is like some kind of a warning to move away, or get ready to face

00:51:53the angry bee.

00:51:54Ouch!

00:51:55That was a painful one.

00:51:57But hey!

00:51:58What?

00:51:59Ouch!

00:52:00Was that another sting?

00:52:01In that case, it's not a honeybee.

00:52:05A honeybee can only sting once.

00:52:07When it does, you can see the small stinger protruding on your skin.

00:52:11Once that's done, the bee can no longer pull the stinger back out.

00:52:15Since the stinger has nerves, muscles, and is part of the bee's digestive tract, the

00:52:19bee doesn't survive.

00:52:22Yellow jackets are a type of wasp that doesn't have such a problem.

00:52:26They will sting you multiple times, as much as possible.

00:52:29Unlike plenty of bees, yellow jackets have a stinger without a barb.

00:52:34It's no fun being around them or running into their nests, which provides home to thousands

00:52:38of jackets, or up to 50,000 in just one summer.

00:52:43They don't produce the buzzing sound like bees either.

00:52:46That happens because of differences in their behavior.

00:52:50Bumblebees and honeybees fly from one flower to another and gather pollen and nectar, which

00:52:55is also food for the colonies.

00:52:57If you see them flying around at grass level, they're probably collecting food they'll

00:53:01later take to their nest.

00:53:04Yellow jackets aren't that much into flowers, so they don't need to shake their wings as

00:53:08intensively as bees.

00:53:09They don't transfer or collect pollen.

00:53:12These wasps are predators that prefer spiders, insects, and decaying fruit.

00:53:16If you're having a picnic with a basket full of tasty food, get ready for an unwanted visit.

00:53:22Cover the food to keep them away.

00:53:25Their most active time is late summer and early fall.

00:53:28Jackets start their colony in the spring.

00:53:30The lone queen does it by herself.

00:53:33She needs to survive the harsh winter conditions first, after which she lays eggs.

00:53:37The colony then grows through spring and summer.

00:53:41When the winter comes, the old queen is done with her work, so she can now pass the crown

00:53:45to the new queen that will start the next cycle.

00:53:48None of the other wasps survive either.

00:53:51Both yellow jackets and bees have black and yellow bodies and are almost the same size.

00:53:56Bees are more hairy and chunky, while yellow jackets are not that furry or fat.

00:54:01They're more smooth and slender.

00:54:04Wasps also have a waist.

00:54:05It attaches their abdomen to the thorax, the body part between the midsection and the head.

00:54:12Honeybees live in tree holes in nests beekeepers provide them with.

00:54:16Honeybees prefer to make their nests in exposed pipes, holes, in walls, old furniture, or

00:54:21even below the ground.

00:54:23They find some old rodent burrows and often make their nests in lawns on spots with no

00:54:28grass, so it's easier to accidentally step on them or disturb them with a lawn mower.

00:54:34Yellow jackets are way more aggressive and fierce than bees since they're predators

00:54:38and have a really strong instinct to protect their nests.

00:54:41They tend to go after people for violating their peace and will follow you over a long

00:54:45distance if necessary.

00:54:48They'll pass all obstacles and wait for their moment.

00:54:51If you're running away from them, don't go into the water and dive in because they'll

00:54:54be patiently waiting for you to run out of breath to take their revenge.

00:54:58Don't run in panic waving your arms around because they'll probably be faster and way

00:55:02more frustrated as they see you as a threat.

00:55:05Just raise your hands and protect the eyes first, then slowly start moving away.

00:55:11Honeybees sting when they really don't have another choice.

00:55:14They're not mean by their nature.

00:55:15Neither they nor wasps are hostile if they don't feel threatened.

00:55:20Yellow jackets are way easier to provoke than bees.

00:55:23When they see something they find dangerous coming towards, they release certain chemicals

00:55:26that alert the family, so they'll chase you.

00:55:30Wasps can make a nest from paper.

00:55:32First they chew up pieces of bark and then spit it out, which is how they make a paper

00:55:35rougher.

00:55:37They all look the same to us, but wasps can recognize each other by identifying unique

00:55:42facial patterns they all have.

00:55:44They come in crazy colors including green, blue, red, and orange.

00:55:49The smallest insect in the world is a parasite wasp, often called a fairy fly.

00:55:54Male wasps are blind, don't have wings, and they're only 0.005 inches long.

00:56:00There are over 30,000 species of wasps, but two groups in general.

00:56:05Social wasps live in colonies, and solitary wasps prefer to have their nests on their

00:56:09own and live alone with their young.

00:56:12Social wasps use the stingers as a way to defend themselves.

00:56:16Solitary wasps use them for hunting, together with the venom they have inside.

00:56:21Solitary wasps aren't into stinging people and won't go after us.

00:56:24They help humans by taking care of insect populations on their plates.

00:56:30Mud dauber wasps are close relatives to ants.

00:56:33The ants started out as some sort of predatory wasp themselves, but ants are even more related

00:56:38to bees than to social wasps, and they all have the same family tree.

00:56:42They have spread all over the Earth's dry land, populating virtually every imaginable

00:56:46ecosystem.

00:56:48There are more than 10,000 trillion ants on our planet at any moment.

00:56:52One study of a Brazilian rainforest says the overall mass of the ants that lived in that

00:56:56area was around four times bigger than the mass of all reptiles, mammals, and amphibians

00:57:01together.

00:57:05Ants are social creatures that live in pretty big colonies.

00:57:08They cover different roles, defending the nest, looking for food, rearing their young,

00:57:12or building nests.

00:57:16Not only their cousins can make a painful sting, ants are fierce too.

00:57:20Bullet ants have the most painful sting of them all, and they live in humid jungle areas

00:57:24like the Amazon.

00:57:26Fire ants wreak billions of dollars worth of damage every year.

00:57:31The total amount includes the cost of medical and veterinary bills to treat their bites.

00:57:35They might be tiny, but have a pretty painful bite that makes you feel like your skin is

00:57:39burning.

00:57:40That's how they got their name.

00:57:43Some bugs out there can only live for a couple of days, or even hours, but ants are among

00:57:47the longest living insects.

00:57:49The queen ant of some species lives up to 30 years.

00:57:53They are some of the world's strongest animals, considering their size.

00:57:56A single ant lifts and carries a burden that's 50 times its body weight.

00:58:00They appreciate teamwork, so you'll often see them working together to move some bigger

00:58:04objects.

00:58:07Ants live on all continents except for Antarctica, same as their cousin wasps.

00:58:12Ants don't have ears.

00:58:14Instead of listening, they feel vibrations coming from the ground.

00:58:18Some don't even have eyes, so they communicate with others using the antennae.

00:58:23Also, they send messages to each other over chemical signals they release through the

00:58:27body.

00:58:29They leave trails of chemical signals that lead to some food sources or to attract a

00:58:33partner.

00:58:35They also send out warnings when they sense there's danger nearby the same way.

00:58:40Their biggest nest ever discovered was more than 3,700 miles wide.

00:58:45It was found in 2000 in Argentina.

00:58:51Thirty-three ant populations got together and created one enormous supercolony, with

00:58:55millions of nests and billions of ants working and living there.

00:59:02Harlequin beetle looks formidable, and it is.

00:59:06This bug's body reaches 3 inches in length, and its front legs are often even longer than

00:59:11that.

00:59:12They help it crawl on trees, getting from branch to branch, and males also use them

00:59:17to impress females.

00:59:22Despite the looks, harlequin beetles aren't really dangerous.

00:59:26They won't bite you even if you corner them.

00:59:29And if you, by any chance, grow cabbage in your backyard, you probably would try to corner

00:59:34them.

00:59:35These bugs feed on its leaves.

00:59:37Still, better not to touch them with your bare hands.

00:59:40They exude a foul-smelling liquid that both stinks and stings, causing skin irritation.

00:59:47Wear those gloves, will ya?

00:59:50You know what also stinks?

00:59:52No, besides my socks.

00:59:54Squash bugs.

00:59:56If you have a garden patch, these pests can be more than just a nuisance.

01:00:01They could spoil the squash you've been lovingly growing for the fall, hence the name.

01:00:06And if you squash them, they begin to smell just awful, hence the pun.

01:00:12Squash bugs are also often mistaken for stink bugs, but those are even more notorious.

01:00:18They begin stinking even if you so much as touch them.

01:00:22Wow, sensitive!

01:00:25Giraffe weevil is probably the most harmless little fella on this list, but not much is

01:00:29known about it yet.

01:00:31It gets its name from the long, spiny neck.

01:00:35This adaptation helps them build nests and fight over other weevils for food and mates.

01:00:41It may be placid, but the red covering of its wings lets predators know the bug is either

01:00:46foul-tasting or poisonous, or both.

01:00:50Likewise, you shouldn't eat monarch butterflies or their caterpillars.

01:00:55These beautiful insects are often kept as pets and were once almost chosen as the national

01:01:01insect of the U.S.

01:01:03But the little-known fact is that they're highly poisonous.

01:01:07Monarchs feed on milkweed, a plant containing a potent toxin.

01:01:11They've acquired immunity to it and, as a side effect, butterflies accumulate the

01:01:15toxin in their bodies.

01:01:17This makes them a very unappetizing dish for birds and other predators.

01:01:22The concentration is so high that even humans that accidentally or not eat a monarch caterpillar

01:01:28can experience quite unpleasant consequences.

01:01:34Mealworm beetles are abundant almost anywhere, so you must've seen them.

01:01:39The most probable place to find them is a poultry farm, though.

01:01:44Mealworm larvae are often used to feed farm birds, and that's where the danger lies.

01:01:51Mealworms carry lots of diseases that can spread among birds and then to humans.

01:01:55They also like to eat chicken food and even insulation on farms, so they're not the

01:02:01best choice of a meal for birds, despite their name.

01:02:04And adult beetles produce a poison that's not harmful in small doses but causes allergy

01:02:10in high concentrations.

01:02:12If you happen to be at a poultry farm, make sure you avoid those beetles!

01:02:17Tiger beetles come in lots of shapes and colors.

01:02:21But they all have two traits in common – long, thin legs and sharp, sword-like mandibles.

01:02:27Those legs allow them to run faster than almost any other insect.

01:02:31So fast, in fact, that when they're on a hunt, they sometimes have to stop and look

01:02:36around for a few seconds.

01:02:38Their eyes and brains simply can't process the picture quickly enough, so they wait for

01:02:43the landscape to load around them.

01:02:46Most tiger beetles are harmless.

01:02:48But if you see one with an orange pattern on its back, don't touch it!

01:02:53These bugs produce cyanide to protect themselves, and this chemical can do a lot of harm both

01:02:58to animals and people.

01:03:00If you touch a tiger beetle and then rub your mouth or eyes, it might cause severe irritation.

01:03:07Oh, look!

01:03:08See that wonderful pattern on a flower over there?

01:03:12Looks like an impressionist painting.

01:03:14And in a sense, it is.

01:03:15That's a Picasso bug!

01:03:18These critters feed on plants and are mostly placid.

01:03:21But think twice if you want to take a closer look.

01:03:24It's not a ladybug.

01:03:26When touched, it'll emit a strong odor that's not exactly flowery.

01:03:31Worse still, you might have a hard time getting rid of the stench even hours after the encounter.

01:03:39Walking out of a pine forest, you notice a weird movement right beneath your feet.

01:03:44It looks like a little fuzzy train that's several dozen feet long.

01:03:48In fact, it's a defense technique of pine processionary caterpillars.

01:03:53They travel nose to tail in large groups to protect each other.

01:03:57They look really particular, but trying to disrupt the column isn't the best idea.

01:04:03Each car of this natural train has hundreds of needle-sharp bristles.

01:04:08If you touch any of them with your bare hand, they'll first cause sharp pain and then

01:04:13some other unpleasant reactions.

01:04:16Predators don't like pine processionaries for the same reason.

01:04:22Asian giant hornets live mostly in Asian countries, but they were reported in North America in

01:04:272019.

01:04:29These beasts are big, yellow, and vicious.

01:04:33It's impossible to confuse a giant hornet with any other bee or wasp.

01:04:37They're much larger and a lot more aggressive.

01:04:41But the worst thing about them is their stinger, which is more than three times longer than

01:04:45that of a honeybee.

01:04:47The stinger contains a really potent venom, and several stings from an Asian giant hornet

01:04:52can bring down even a large animal and a human too.

01:04:57And if that wasn't enough, these creatures can even spray their venom, aiming at the

01:05:01eyes.

01:05:02Needless to say, that's an unforgettable experience.

01:05:07Linomia is a rather unassuming little moth that doesn't pose a threat to anyone.

01:05:13But before it becomes a moth, it has to go through a caterpillar stage.

01:05:18And that's when you don't want to cross its path.

01:05:23Linomia caterpillars are covered in hair-thin bristles that contain a powerful venom.

01:05:29But even if you know not to touch them, you still might get pricked.

01:05:34Caterpillars perfectly blend in with tree trunks to add to their protection.

01:05:38A person might unknowingly lean on a trunk with linomias huddled on it, and they won't

01:05:43hesitate to stick those needles into the unlucky guest.

01:05:48If you get stung, immediately seek medical attention.

01:05:51Now, let's admit, all centipedes are terrifying.

01:05:56And perhaps one of the most horrible species is a Texas red-headed centipede.

01:06:01First of all, it looks like it's ascended from your deepest, darkest nightmares.

01:06:05A black, sectioned body, dozens of yellowish legs that look more like claws, and a red

01:06:11head with two long horns.

01:06:13A picture enough to make me run for it in a split second.

01:06:18Being pretty large, these crawlers have a voracious appetite, munching on toads, lizards,

01:06:25and an occasional rat.

01:06:26Sometimes, when desperate, they can even catch a bat right in the middle of a flight.

01:06:32And of course, red-headed centipedes are venomous, fitting for such an appearance.

01:06:37Luckily, they're not interested in humans.

01:06:40And that's mutual.

01:06:43This critter isn't large, but it's very defensive, meaning you don't want to cross

01:06:48it.

01:06:49Its name speaks for itself – the Devil's Coach Horse.

01:06:53A total black bug that resembles an earwig, it will raise its behind and open its powerful

01:06:59jaws when threatened.

01:07:01This pose makes it look like a scorpion, and at this point, better back off.

01:07:07If you don't, the Devil's Coach Horse will start to emit a foul stench and ooze

01:07:12unpleasant liquid from its mouth for defense.

01:07:15And if that doesn't scare you off, it will eventually bite, which is quite painful, y'know.

01:07:22Just leave the beast alone, okay?

01:07:26Velvet ants aren't ants at all.

01:07:28They're a kind of wingless wasp that just look a lot like ants.

01:07:33These bugs don't form large colonies and usually live alone, hiding in tall grass.

01:07:38This behavior has given them another nickname – cow ants.

01:07:43Because when a cow is grazing nearby, it might step on a velvet ant and get a painful bite

01:07:48in return.

01:07:51Humans also get bitten sometimes, especially if they walk barefoot.

01:07:56Velvet ants are venomous, but their venom is less potent than that of bees, so it's

01:08:00not really dangerous.

01:08:02Still, the pain from such a bite is serious.

01:08:06And if you want to squash this bug, good luck!

01:08:10They have an unusually tough carapace that protects them from other stinging insects

01:08:15and even birds.

01:08:18Puss moths get their name from their furry, fuzzy appearance.

01:08:22It's like their little fluffy flying kitties.

01:08:26Moths might be cute, but their caterpillars, as always, should only be looked at, not touched.

01:08:33Despite the even fuzzier looks, a puss caterpillar is covered in thousands of hollow spines that

01:08:39break off the critter's back upon contact and inject their venom.

01:08:44And what a venom it is!

01:08:47Puss caterpillars are the most venomous caterpillars in the US.

01:08:51One sting of this little monster can result in days and even weeks of sickness.

01:08:56And if you're allergic to it, then I can only wish you best of luck.

01:09:04Around 80% of all animals on Earth are insects.

01:09:09But how well do you know their world?

01:09:11Let's see if you can guess whether these amazing facts are myths or true.

01:09:17Here's the first one.

01:09:19Cockroaches can run on two legs, just like humans.

01:09:23Myth or true?

01:09:25It's correct.

01:09:27Cockroaches don't do it just for fun.

01:09:29Running on two legs is more energy efficient because it's easier for their little brains

01:09:33to process.

01:09:35If you take a closer look at the cockroach, you're going to spot that all pairs of legs

01:09:40have different lengths.

01:09:42This creates unnecessary drag when the cockroach needs to reach high speeds.

01:09:47Their nervous system can get overloaded and confused by trying to control all three pairs

01:09:51of legs.

01:09:53So it chooses to move just one pair.

01:09:55The rear legs that use energy most efficiently.

01:10:00Check this out.

01:10:01A full moon makes mosquitoes bite 500% more actively.

01:10:07Myth or true?

01:10:08True.

01:10:10Just like werewolves, mosquitoes get fierce when the moon is full.

01:10:14That's because they use visual cues and receptors to spot their next dinner.

01:10:18And it's way easier to do so when the moon is full.

01:10:24Mosquitoes spot movement by detecting infrared radiation emitted by warm bodies at distances

01:10:29of up to 115 feet.

01:10:33Saltmarsh mosquitoes took this to the next level.

01:10:37They're such gourmets that they can travel up to 40 miles just for the sake of eating.

01:10:45Only male mosquitoes bite.

01:10:46Does it sound real?

01:10:48Nope.

01:10:49In fact, only female mosquitoes do bite people or animals because they need a blood meal

01:10:55to produce eggs.

01:10:56On average, they take in about 5 millionths of a liter during one feeding.

01:11:02Meanwhile, male mosquitoes prefer eating plant juices, such as nectar.

01:11:07It's enough for them to get the necessary sugar and boost their energy levels.

01:11:11And since males don't bite, they cannot transmit diseases.

01:11:15But females, on the other hand, can get infected with germs when they bite sick people or animals.

01:11:23Here's the next fact.

01:11:24Alligator ticks are called so because they can reach the size of a crocodile.

01:11:29True or false?

01:11:31That's false.

01:11:32But still, it's the largest aquatic insect on Earth.

01:11:36According to Guinness World Records, toe biter, or sometimes called an alligator tick, can

01:11:41grow to be more than 4 inches long, which is basically the size of an average leaf.

01:11:47They can be found around the world, but they're especially common in North America.

01:11:53Toe biters perfectly blend into the landscape because their dark brown body mimics the leaves

01:11:59of the wetlands.

01:12:01They're predatory by nature.

01:12:02Usually, they eat small tadpoles and other insects.

01:12:06But sometimes, they take down bigger prey, like snakes and even turtles.

01:12:11Those who experienced meeting these creatures claim that their bites are the most painful

01:12:16injuries a human can suffer.

01:12:20Flies can poison your food just by landing on it.

01:12:23Myth or true?

01:12:25Unfortunately, that's true.

01:12:28Not only are flies annoying, but they also regurgitate some of their stomach contents

01:12:32when they land on your food.

01:12:34And house flies are just one of many fly species that do so.

01:12:41It happens because flies don't have teeth.

01:12:44Instead of chewing, they use their straw-shaped mouth to slurp their food.

01:12:48They secrete digestive juices on their future meal as they land on it, and once the food

01:12:54has been liquefied, the flies are able to slurp it up.

01:12:58But the real danger lies with their feet, not their mouths.

01:13:02Flies spend a lot of time walking on all sorts of dirty things, which can be sources

01:13:07of disease.

01:13:08Studies have revealed that flies can transfer bacteria even if they're only in contact

01:13:13with an area for a short period of time.

01:13:16So if you ever spot some flies hanging around your food, it makes sense to cover it.

01:13:21Or if you're concerned about your health, even forget about finishing your meal.

01:13:28Here comes the next fact.

01:13:30Males of toe biters carry their eggs on their backs.

01:13:34That's false.

01:13:35In fact, they lay eggs on their males' backs.

01:13:38After that, the future father carries the eggs as a backpack wherever he goes.

01:13:44As sweet as it sounds, this sight is still pretty disgusting, and it might send shivers

01:13:48down your spine.

01:13:51And more bad news.

01:13:52Even though they're called water bugs, they can fly.

01:13:55So don't just watch out below because they can approach from the sky.

01:14:01Next fact.

01:14:02Ants are one of the most dominant animals on the planet.

01:14:06True or myth?

01:14:08True.

01:14:09Collectively, ants alone contribute up to 20% of the entire animal biomass on the planet.

01:14:17These creatures are pretty ancient.

01:14:19They appeared around 160 million years ago and took over a wide variety of ecological

01:14:25niches.

01:14:27As a result, today they count about 16,000 different species with over 10,000 trillion

01:14:34individuals.

01:14:37Check this out.

01:14:39Butterflies taste with their feet.

01:14:41Myth or true?

01:14:44Sounds like fiction, but it's true.

01:14:47Butterflies have taste receptors on their feet to help them find their host plant and

01:14:51select food.

01:14:54Female butterflies land on various plants and drum the leaves with their feet.

01:14:58This technique helps them squeeze juices from the plant.

01:15:03Their legs have spines with receptors, helping them to detect the right match of chemicals

01:15:08in the plant juice.

01:15:10And once a female butterfly finds the proper plant, she lays eggs.

01:15:15Also, both male and female butterflies step on their potential food to sense the content

01:15:21of dissolved sugars.

01:15:23Just imagine what human restaurants would look like if people were tasting with their

01:15:27feet.

01:15:30Next fact.

01:15:31Butterfly wings are transparent.

01:15:33Does it sound real?

01:15:36That's true.

01:15:37Butterflies have the image of colorful and vibrant creatures.

01:15:41But strangely enough, their wings are transparent.

01:15:46They are covered with thousands of tiny scales.

01:15:49And these scales reflect light in different colors.

01:15:53But underneath all of those scales, a butterfly wing consists of several layers of chitin.

01:16:00It's the same protein that makes up an insect's exoskeleton.

01:16:04These layers are so thin that you can see right through them.

01:16:09Butterflies only live from two to four short weeks, and you can determine their age by

01:16:14the quality of their wings.

01:16:16With age, the scales begin to fall off the wings, leaving transparent spots.

01:16:24Fruit flies were the first living creatures to be sent into space.

01:16:28Myth or true?

01:16:30True!

01:16:31A long time before sending dogs or humans into space, scientists studied fruit flies'

01:16:36reactions to radiation and space flights.

01:16:39This helped to predict how space conditions and zero gravity might influence human beings

01:16:45because we share many genes with fruit flies.

01:16:50And after several decades of research, on February 20, 1947, fruit flies became the

01:16:55first living organism to go to space and return.

01:17:01Next fact.

01:17:03Caterpillars have two eyes.

01:17:05Myth or true?

01:17:08That's a myth.

01:17:09In fact, the majority of caterpillars have 12 eyes called stemata.

01:17:14If you look closely, you can see six tiny eyelids on each side of the caterpillar's

01:17:20head.

01:17:21One pair of eyes is usually placed closer to the antennae.

01:17:26It's easy to believe that 12 eyes would guarantee excellent eyesight, but that's not the case.

01:17:32A caterpillar uses them to distinguish light and dark and navigate its way.

01:17:37That's why sometimes caterpillars move their heads from side to side.

01:17:41Maybe they just love rap music.

01:17:44But scientists believe that it helps caterpillars understand the distance between objects.

01:17:49A few species of caterpillars have between 10 and 14 eyes.

01:17:54But these are usually more primitive forms, which also have several features making them

01:17:59different from other moths and butterflies.

01:18:04Scorpions can breathe underwater.

01:18:06Myth or true?

01:18:09That's false.

01:18:10Although scorpions are not very good swimmers, they can still store oxygen to survive underwater.

01:18:16And some species can hold their breath for up to six days.

01:18:21Scorpions can survive underwater thanks to the so-called book lungs, which actually look

01:18:26like a book.

01:18:27The pages of that book act like membranes that store oxygen.

01:18:32Since scorpions don't waste a lot of oxygen on dry land, they can just store the rest

01:18:37in their lungs.

01:18:38And once a scorpion enters the water, it has around 48 hours to hang out carefree.

01:18:44After that, it will need to come out of the water for the next inhale.

01:18:48And this cute little creature is called the northern pseudoscorpion.

01:18:52It's the breath-holding champion among scorpions.

01:18:55It can hold its breath for up to 17 days.

01:18:59Let's just hope it doesn't learn to fly.

01:19:02Well, meet the tiny terrors of our world.

01:19:07Fire ants.

01:19:08When they sting, they inject venom that can cause serious trouble.

01:19:12For most people, it's just a fiery sensation and raised bumps.

01:19:16But for others, especially those who are allergic to it, it's life-threatening.

01:19:21These ants set up their camps right under your feet.

01:19:24They're quick to swarm and are fiercely protective of their colonies.

01:19:28They show no mercy to intruders.

01:19:30Their stings are rated about 1.2 on the Schmidt Insect Sting Index, where 4 is the maximum.

01:19:38It feels like a sudden jolt, but the sensations are less burning than when a bee stings you.

01:19:44They originated in tropical regions like Central and South America.

01:19:48But now you can find them even in some temperate zones like North America.

01:19:53In their colonies, fire ants have a strict hierarchy of queen, winged males and females,

01:19:59and different types of workers.

01:20:01They communicate through chemicals and sounds.

01:20:04The most famous member of this genus is the red imported fire ant.

01:20:09They've come from South America and invaded the southern US.

01:20:12They build large mounds, making farming difficult and damaging crops.

01:20:17It's almost impossible to control them.

01:20:19But on top of that, there's now the rise of another invasive species – the tawny

01:20:24crazy ant.

01:20:25This one poses a threat to native ecosystems.

01:20:28Turns out ants can be dangerously unfriendly.

01:20:33Colorful blister beetles are among the 10 most dangerous insects in the world.

01:20:37Luckily, they're not lethal to humans unless they go for you in a big pack.

01:20:42However, they pose a serious threat to large animals, such as horses.

01:20:47Blister beetles produce a toxin called cantharidin, which causes skin blistering in humans.

01:20:53In the past, people believed it could treat warts and even rabies, and some even used

01:20:57it in love potions.

01:20:59However, it's a risky game.

01:21:01In the 1950s, a man was jailed for giving cantharidin-laced candies to two women, resulting

01:21:07in a tragic outcome.

01:21:09These beetles are not to be messed with.

01:21:12Handling them or ingesting them is very dangerous.

01:21:14They're attracted to alfalfa and hay.

01:21:17If a horse eats either of those, even a few beetles can release enough cantharidin to

01:21:22end it.

01:21:25This cute caterpillar from South America is called Linomia obliqua, and it's the most

01:21:30dangerous caterpillar on Earth.

01:21:32It's responsible for several fatalities due to its potent venom.

01:21:36It's the larval stage of the giant silkworm moth.

01:21:40When it grows up, it becomes a beautiful and harmless silkworm.

01:21:44If you see them as youngsters, it's better to stay away.

01:21:48Its toxicity stems from venom-injecting bristles.

01:21:51They serve as a defense mechanism against predators.

01:21:54The poison messes up how your blood clots and can cause really bad symptoms like burning

01:21:59feelings, throwing up, kidney problems, and sometimes even lethal outcomes.

01:22:05A single bite probably won't lead to anything horrifying.

01:22:08It delivers only a tiny amount of venom.

01:22:11These caterpillars tend to congregate, and they're quite good at camouflage.

01:22:15This increases the risk of multiple stings.

01:22:20Locusts themselves aren't dangerous to humans.

01:22:23They're ordinary, loud grasshoppers.

01:22:26But they're infamous for their swarming behavior.

01:22:28These swarms often happen when there's a dry period with no rain.

01:22:32And then suddenly, a lot of rain falls, and plants start growing fast.

01:22:37Once it begins, it's nearly impossible to stop.

01:22:40They can become a destructive force within minutes.

01:22:43Throughout history, locust plagues have been devastating, wreaking havoc on crops and farmland.

01:22:49What's interesting is that the term locust can mean different things depending on where

01:22:53you're from.

01:22:54In some places, we're talking about cicadas, which are also known for their loud sounds.

01:23:00But true locusts are ancient creatures, relatively unchanged since the Triassic era.

01:23:05They're among the oldest insects on Earth.

01:23:08Wasps, hornets, and even bees can be extremely dangerous, especially to those allergic to

01:23:15their stings.

01:23:16The Asian giant hornet is the largest of the wasps.

01:23:19It can reach up to 2 inches in size.

01:23:22It packs a powerful venom that can cause serious discomfort and even spray into people's eyes.

01:23:28There's an even more venomous species in the Philippines called Vespa luctuosa, not to

01:23:33be confused with Expecto Patronum.

01:23:35Any Harry Potter fans?

01:23:37Anyway, fatalities because of wasps or bees are rare but not unheard of.

01:23:43In the UK, about 10 people pass away each year from bee or wasp sting reactions.

01:23:49Always stay cautious.

01:23:50All these insects are very territorial and will fiercely defend their hives.

01:23:55When provoked, they signal danger to nearby bees and instigate a mass defense effort.

01:24:01If you need to handle them, it's best to call professionals.

01:24:07A flea is tiny and humble, but it left a colossal impact on human history and health.

01:24:13They're not just annoying pests.

01:24:15They're notorious carriers of various human conditions and are responsible for some of

01:24:19the worst outbreaks in history.

01:24:22Back in the 14th century, I forget where I was, but the bubonic plague wiped out over

01:24:2825 million people in Europe, and fleas were a big part of spreading it.

01:24:33Fleas spend their lives searching for warm-blooded hosts to feed on, whether it's reptiles,

01:24:38mammals, pets, or humans.

01:24:40Despite their tiny size and absence of wings, they make up for it with impressive jumping

01:24:45abilities.

01:24:46They can leap 6 feet and jump over 1,200 feet in the air.

01:24:51A flea bite might seem like a minor annoyance, causing itching and inflammation.

01:24:56But a lot of them can lead to anemia in their hosts.

01:24:59Of course, the most dangerous part about them is the viruses, bacteria, and worms they transmit.

01:25:06Kissing bugs mostly live in both Americas, with smaller populations in Africa and Asia.

01:25:12Despite the friendly name, they're great at passing on bacteria, viruses, and parasites.

01:25:18One of the parasites they carry is trypanosoma cruzi.

01:25:22It's the culprit behind illnesses that affect millions globally and claim thousands of lives

01:25:27each year.

01:25:28What's interesting is that symptoms don't often appear until 10 or 30 years after being

01:25:33bitten.

01:25:34They typically manifest as heart failure, digestive issues, or nervous system problems.

01:25:39They don't actually kiss you.

01:25:41They suck on you and are attracted to their prey by breath.

01:25:45If you breathe through your mouth, you're a target.

01:25:47They're messy biters, often biting chaotically and almost uncontrollably, which only adds

01:25:53to their unsettling nature.

01:25:58Many have heard of the tsetse fly, an unusual and scary insect from tropical Africa.

01:26:03These flies are carriers of one of the most devastating human diseases, sleeping sickness.

01:26:09Similar to the kissing bug, the tsetse fly transmits trypanosomes, the parasites that

01:26:14cause sleeping sickness.

01:26:16They acquire this parasite from an infected host or from within the fly's own body.

01:26:21Sleeping sickness doesn't strike immediately.

01:26:23After a bite, it takes 1-3 weeks for symptoms to appear.

01:26:27Fever, headaches, joint pains, and itchiness.

01:26:31As the illness progresses, it can invade the nervous system, leading to confusion, insomnia,

01:26:37and loss of balance.

01:26:38Without treatment, it can result in a coma and then a fatal outcome.

01:26:42Luckily, sleeping sickness can be treated, and the number of losses is declining.

01:26:48The tsetse fly holds historical significance too.

01:26:51Its presence has hindered European colonial expansion in Africa.

01:26:57And the crown of the most dangerous insect in the world goes to the mosquito.

01:27:03It's no surprise why.

01:27:04Despite their small size, they wield a massive impact.

01:27:08They're not only responsible for more human losses annually than any other animal, but

01:27:13they've also left an indelible mark on history.

01:27:16These little insects influence the rise and fall of entire civilizations.

01:27:20For example, malaria significantly weakened ancient civilizations such as in Rome and

01:27:26Greece.

01:27:27What's interesting is that it's not just the mosquitoes themselves that are dangerous,

01:27:31but the parasites.

01:27:33Bacteria and viruses carry and transmit through their bites.

01:27:37These tiny horrors spread a buffet of diseases.

01:27:40Despite malaria, there's also yellow fever, which, just like with the tsetse fly, hindered

01:27:45European colonization efforts in tropical regions.

01:27:49The scariest one of them is the Anopheles mosquito.

01:27:51It's the apex predator of the insect world.

01:27:55It's responsible for more fatal outcomes and illnesses than any other insect.

01:28:00So how do we combat these tiny yet mighty foes?

01:28:04With prevention.

01:28:05We need to eliminate standing water in our surroundings and practice mosquito control

01:28:10measures.

01:28:11We must always stay one step ahead to protect ourselves and our communities from dangerous

01:28:16insects.

01:28:24A word of warning, when you're in Australia, never stick your finger into these holes.

01:28:28It might be home to burrowing spiders.

01:28:32Some species have a bite powerful enough to pierce nails.

01:28:35It feels similar to a hammer on your finger because of the venom.

01:28:39So always give your boots and outdoor clothes a quick check to be safe.

01:28:43Animals sometimes make homes or look for food in them, especially bandicoots.

01:28:49Silk-lined burrows and shady spots might belong to funnel-web spiders.

01:28:53The silk works as a trip-line to alert the spider inside about what's happening outside.

01:28:59Look for shiny dark brown to black spiders with finger-like spinnerets at the end of

01:29:04their abdomen.

01:29:05Then you'll find them.

01:29:07Males have a hefty mating spur sticking out of the middle of their second pair of legs.

01:29:11When these spiders feel threatened, they make aggressive moves, rearing up and showing off

01:29:16their startling fangs.

01:29:18These spiders, which belong to the Erinita order, are known for their funnel-shaped webs

01:29:23that widen at the entrance.

01:29:25They patiently wait in the narrow funnel for prey to touch the web, then swiftly capture

01:29:30it.

01:29:31In Australia, large brown spiders frighten people due to their venomous bites.

01:29:35They are infamous for causing people to lose their lives in southern and eastern Australia,

01:29:40particularly in the Sydney area since the 1920s.

01:29:44Quick access to the antidote after a bite is crucial in preventing severe consequences.

01:29:51The next spider is one of the world's most dangerous venomous spiders.

01:29:55Phonutria nigrivitor is a spider living in South America.

01:29:59People often call it the Brazilian wandering spider.

01:30:02You see, in Brazil, 4,000 people get bitten by this critter each year.

01:30:07The bites can cause serious issues, such as hypertension, blurred vision, sweating, and

01:30:11vomiting.

01:30:13You wouldn't want to meet with this creature as you can also face way more severe consequences

01:30:17than blurred vision.

01:30:19In some situations, its kiss can take a life.

01:30:23Apart from messing with humans, this spider has a diverse menu, including crickets, katydids,

01:30:28and even larger options like tree frogs, lizards, and bats.

01:30:33Operating under the cover of darkness, these creatures are the most active during the night.

01:30:38They ambush their prey instead of relying on webs.

01:30:41In the daytime, they seek refuge beneath logs or in narrow crevices.

01:30:45They love to be around banana trees, but can be found in urban areas and inside homes too.

01:30:52If you spot them one day, be prepared.

01:30:55This creature's body is covered with thick brown hair and is not that small.

01:31:00In 2013, a London family had to leave their home due to an infestation of Brazilian wandering

01:31:07spiders.

01:31:08The trouble began when an egg sac, hidden in a bunch of bananas, made its way to their

01:31:12local grocery store.

01:31:14No one noticed.

01:31:15When the family bought the bananas, the egg sac broke open.

01:31:19Potentially lethal spiders spread around the house.

01:31:22Over 2,500 people visit poison control centers annually in the US.

01:31:28Black widows are spiders with the signature hourglass mark on their bellies.

01:31:32Well, let's talk about their bite.

01:31:34These creatures have a bad reputation because their venom is supposedly 15 times stronger

01:31:40than what rattlesnakes pack.

01:31:42When they bite humans, the bite causes muscle aches and nausea.

01:31:46The venom can even mess with breathing by paralyzing the diaphragm.

01:31:50Despite these cases, most people who get bitten don't end up with serious issues unless

01:31:55they're elderly or very young.

01:31:58These sneaky creatures don't pick just one spot to hang out.

01:32:01You can find them in wood piles, burrows, or among plants that act as scaffolding for

01:32:06their webs.

01:32:07Black widows are especially dangerous for other insects and their mates.

01:32:12After a not-so-romantic mating dance, ladies sometimes go all Hannibal Lecter on their

01:32:17mates.

01:32:18These spiders are architects too, spinning massive webs where females stash a cocoon

01:32:23loaded with hundreds of eggs.

01:32:26Baby spiders move out once they hatch, but the web stays put.

01:32:30Those webs are also traps.

01:32:32Different kinds of prey later join the black widow's spooky snack collection.

01:32:38Yellow-sacked spiders range in size from approximately 0.12 to 0.6 inches and construct silken tubes

01:32:46under stones, in leaves, or in grass.

01:32:49They're found across the United States and southward toward Mexico and South America.

01:32:54They are venomous to humans and, unfortunately, are commonly spotted indoors.

01:32:59The venom of the yellow-sacked spider contains cytotoxin.

01:33:03This is a substance that can damage or impair cell function.

01:33:07Reactions like redness and swelling at the bite site are common.

01:33:11Yellow-sacked spiders are not known for their calm nature either.

01:33:14For instance, a female yellow-sacked spider may bite when protecting her eggs.

01:33:19These spiders usually come in different light colors.

01:33:22They can be a hassle for people in more than one way.

01:33:25Your car can be in danger too.

01:33:27On rare occasions, they may even set up nests in car engines.

01:33:34Moving on to wolf spiders.

01:33:35They're part of a large and widespread group found worldwide.

01:33:39They're named this way for their wolf-like hunting behavior of chasing and pouncing on

01:33:43prey.

01:33:44Around 125 species exist in North America, and approximately 50 live in Europe.

01:33:51These spiders are typically dark brown, with long, broad, hairy bodies and sturdy elongated

01:33:56legs.

01:33:57Like me.

01:33:58Just kidding.

01:33:59They're super speedy.

01:34:01While they usually create silk-lined, tubular nests in the ground, some may conceal the

01:34:05entrance with debris.

01:34:07Wolf spiders build turret-like structures.

01:34:09A few species also spin webs.

01:34:12Wolf spiders may bite in self-defense.

01:34:15They are venomous, but their bites are not considered dangerous.

01:34:19Some people who are allergic to spider bites may experience nausea, dizziness, and an elevated

01:34:24heart rate.

01:34:25The bite of the spider's large fangs is similar to a bee sting, so it can cause a physical

01:34:30wound at the bite site, and the venom may cause itchiness.

01:34:34The combination of their powerful bite, rapid movements, and startling appearance can be

01:34:39quite unsettling.

01:34:43Beware of the red-backed spider, a close relative of the notorious black widow.

01:34:48It used to live in Australia, yet it has managed to spread its web across New Zealand, Belgium,

01:34:53and Japan through grape exports.

01:34:56The distinctive red stripes or hourglass marks on their black backs are more noticeable in

01:35:01females.

01:35:02If you disturb a female, and you'll see how she can defend her eggs, you're likely to

01:35:07get bitten.

01:35:08These spiders can sneak into shoes or clothing, lurking against the victim's skin while they're

01:35:13dressing.

01:35:14Both male and female red-backs have a venomous bite.

01:35:18Their venom is a cocktail of neurotoxins.

01:35:21It can cause sweating, rapid heartbeat, and swollen lymph nodes.

01:35:25The red-back has control over the venom dose, so symptoms vary based on how much is injected.

01:35:32Australia deals with over 250 red-back bites annually, many requiring anti-venom treatment.

01:35:38The latest case, when a person lost their life after being bitten, dates back to 1956.

01:35:44Yet it can happen, so stay vigilant and cautious around these stealthy spiders.

01:35:50Let's talk about the heavyweight champion of the spider world, the Therophosus blondi,

01:35:55casually known as the Goliath bird-eater.

01:35:58This giant tarantula can stretch up to 11 inches and tip the scales at 6 ounces.

01:36:04To put it in perspective, this spider is big enough to cover your dinner plate and is certified

01:36:09by the Guinness World Records.

01:36:11The nickname might make you picture a tarantula feasting on a hummingbird, but that's more

01:36:16of an artistic exaggeration dating back to the 18th century.

01:36:20These spiders are more into munching on arthropods and rarely go for bird snacks.

01:36:25Goliath bird-eaters don't bother with webs like their spider buddies.

01:36:29Instead, they're all about silk, using it to line their cozy burrows beneath the forest

01:36:34floor.

01:36:35The spider itself looks dangerous, but its bite almost never requires a doctor's visit.

01:36:40It feels more like a wasp sting.

01:36:43Goliath bird-eaters are the biggest spidey on Earth.

01:36:46On the other side of the spectrum, we have this guy from Colombia.

01:36:50They are among the tiniest spider species.

01:36:53Grown-up males of this species are 0.015 inches long, tinier than your average pinhead.

01:37:00Females are usually a bit larger.

01:37:02Well, that was creepy, wasn't it?

01:37:05So Barry is running along the shore of a lake as fast as possible.

01:37:09He knows that if he stops, his life will turn into a nightmare in no time.

01:37:14A thousand mosquitoes are about to bite him.

01:37:17But what he doesn't know is that he'll be okay after all.

01:37:21So don't be afraid, Barry, and stop.

01:37:25Mosquitoes are slow.

01:37:26They fly at a little more than 1 mile per hour.

01:37:29And you can't run forever.

01:37:32So after a couple of hours of pointless running, Barry stops.

01:37:36He sweats, and emits a smell attractive to insects.

01:37:41One little mosquito flies up to him.

01:37:43It buzzes next to his ear, sits on his sweaty neck, and bites.

01:37:47The insect pierces the skin with a special mouth apparatus called a proboscis.

01:37:53The mosquito starts pumping blood through this needle.

01:37:56Its saliva gets into Barry's body and causes an allergic reaction.

01:38:00More precisely, it's Barry's immune system that starts this reaction.

01:38:04It perceives the mosquito's saliva as an enemy and sends a unique chemical substance

01:38:10to the bite site.

01:38:12The fight between this substance and the invader causes an allergic reaction.

01:38:17Redness, swelling, and the worst thing, itching.

01:38:20Barry can scratch himself for several hours or even days.

01:38:24It all depends on how his body will react to the bite.

01:38:27The mosquito fills up with Barry's blood and flies away.

01:38:31It does it not for pleasure, but because it needs to lay eggs.

01:38:35Protein in the blood is necessary for these insects to reproduce.

01:38:40Their eggs can't grow without this substance.

01:38:42Yeah, almost all biting mosquitoes are female.

01:38:47Female mosquitoes prefer plant and flower nectar.

01:38:49Hey, they're guys.

01:38:52So the female mosquito flies away from Barry.

01:38:55She sits down on the shore of the lake, where a large mosquito base is located.

01:39:00Here these insects lay eggs, drink water, and chill in the sun.

01:39:04There are several hundred thousand of them, and they're all hungry.

01:39:08The female mosquito brings with her the smell of Barry's sweat, which is attractive to

01:39:13the rest of the mosquitoes too.

01:39:16There are about 3,500 species of these insects on Earth.

01:39:21Some of them love the smell of sugar, perfume, or deodorant.

01:39:25And some enjoy the smell of dirty feet.

01:39:28Your attractiveness to mosquitoes also depends on what you've eaten today.

01:39:33Lots of candies and chocolate?

01:39:35Great, now mosquitoes feel a faint sweet smell coming from you.

01:39:39Have you eaten garlic and onions?

01:39:42Mosquitoes probably won't want to deal with you.

01:39:44And not only they, most likely.

01:39:47So the smell of Barry's sweat is perfect for all mosquitoes on the shore.

01:39:52They go mad, take off, and head for the poor guy.

01:39:56If you walk near the water when the evening comes, if you're sweaty, wearing black clothes,

01:40:00and have O-type blood, then you have all the chances to get bitten by mosquitoes.

01:40:05And Barry meets all the criteria.

01:40:08The first mosquitoes land on Barry's feet.

01:40:11They bite him and start pumping blood.

01:40:14One tiny mosquito can draw a droplet of blood the size of a half a grain of rice.

01:40:19It's nothing at all.

01:40:21But several dozen of these bites?

01:40:23It's bad.

01:40:24Barry fights mosquitoes off with his hands, but the insects keep coming.

01:40:28They can't miss such a delicious dinner.

01:40:3110, 20, 50, 100 mosquitoes!

01:40:35They cover Barry's legs.

01:40:37The skin swells and turns red.

01:40:39Barry feels a burning sensation.

01:40:42His immune system is working at 100%, trying to reduce the damage and drive the enemies

01:40:47away.

01:40:48But the more actively Barry's body defenses work, the worse he feels.

01:40:53Mosquitoes sit on his hands and on his wet T-shirt stuck to his body.

01:40:57Yes, their mouthpiece can pierce a thin layer of fabric.

01:41:01Barry tries to run away.

01:41:02He stumbles over a rock and falls.

01:41:06Some insects finish their feast and fly away to tell their friends about the free food.

01:41:11Mosquitoes from all over the lake come to try Barry.

01:41:14Two hundred mosquitoes are drinking his blood.

01:41:17Three, five, seven, nine hundred.

01:41:20Now one thousand mosquitoes have bitten him.

01:41:23Together they have pumped out a small glass of blood.

01:41:27But the worst thing is, they continue biting him.

01:41:30Nothing can stop them now, even though they were supposed to bite him only a thousand

01:41:34times.

01:41:35Well, the only chance to escape is water.

01:41:38Barry, ignoring the itch, gets up and runs to the shore of the lake.

01:41:42Meanwhile, one hundred thousand mosquitoes have already bitten him.

01:41:46Sorry, Barry, but we have to entertain the audience.

01:41:49Don't worry, your recovery will be fast.

01:41:51He's getting closer and closer to the water.

01:41:55Mosquitoes are flying in front of his face, so he can't see the road.

01:41:58But Barry keeps running, waving his hands.

01:42:02Meanwhile, you know this moment when you're sleeping and one mosquito flies into the room

01:42:06through the window?

01:42:08Just one?

01:42:09But its squeaky sound is so annoying!

01:42:12And now, imagine a million mosquitoes making this noise.

01:42:16It's like a saxophone playing high notes.

01:42:18Sorry if you're a sax player.

01:42:20Well, Barry is slowing down.

01:42:23He's exhausted, and his heart is beating too fast.

01:42:26He no longer feels bites and itches.

01:42:28His body is becoming weak, but he's still moving toward the lake.

01:42:33Mosquitoes have already taken three soda cans of blood from him.

01:42:37And this is serious.

01:42:38Barry is running a fever and has clouded consciousness.

01:42:42His immune system is not coping.

01:42:44Barry can't run anymore.

01:42:46He's struggling to walk.

01:42:48It's getting harder to make every next step.

01:42:51The shore is only a few feet away, but it doesn't matter anymore since he has no energy

01:42:56to move.

01:42:57So, he just sits on the grass and accepts the situation.

01:43:00He's lost a large soda bottle of blood, and this is a lot.

01:43:05This is probably the most large-scale attack of mosquitoes on humans.

01:43:10And then, at the very last moment, salvation appears.

01:43:14A frog croaks nearby.

01:43:16And another one.

01:43:17Several dozen jumping animals are approaching the shore.

01:43:20They release their tongues like spears and catch mosquitoes.

01:43:24This gives Barry hope.

01:43:26He makes a last-ditch effort to reach the lake.

01:43:29He jumps in.

01:43:30Yeah!

01:43:31What a relief!

01:43:32Cold, fresh water envelops his whole body and relieves the itching and irritation from

01:43:37the bites.

01:43:39He waits in the water while the frogs dine on the mosquitoes.

01:43:42The remaining insects fly away.

01:43:45Barry crawls out of the lake.

01:43:47He sees frogs catching mosquitoes and realizes that these annoying insects are necessary

01:43:53for our planet.

01:43:54Mosquitoes live thanks to these tiny monsters.

01:43:57And besides frogs, there are many other animals that feed on mosquitoes.

01:44:01Lizards, spiders, bats, birds, turtles… it's a huge list!

01:44:07Mosquitoes are an endless source of food for them.

01:44:09One pair can lay 200 eggs.

01:44:12They grow fast, and their lives are short.

01:44:14But if all these insects disappear, an ecological catastrophe may begin.

01:44:20Entire animal species may vanish from the face of the Earth.

01:44:24The frogs that save Barry wouldn't exist.

01:44:27Without frogs, the population of other insects, like flies, would begin to grow.

01:44:32They would reproduce uncontrollably.

01:44:35And then, like falling dominoes, other problems will follow.

01:44:39So, Barry, don't be angry at mosquitoes.

01:44:42It's just nature.

01:44:43You better deal with your itchy problem.

01:44:46His whole body is red, covered with little bumps.

01:44:49He starts scratching himself, but this doesn't help.

01:44:51He only makes it worse.

01:44:54As long as mosquito saliva remains in his body, and the immune system fights it, Barry

01:44:59will feel this itch.

01:45:01Fortunately, there are many oils and ointments to alleviate these effects.

01:45:05But the best way to get rid of the problem is to ignore it.

01:45:09Barry just needs to distract himself with something.

01:45:12Then, the urge to scratch will disappear.

01:45:16Barry has survived so many mosquito bites without harmful consequences.

01:45:20But some people have problems dealing with just one.

01:45:24It depends on whether a person has allergies.

01:45:26Some have a small itchy bump, and others have severe inflammation.

01:45:31As for Barry, wasn't he swell?

01:45:33I mean, didn't he swell?

01:45:35Ok, I'll stop.

01:45:37The best way to protect yourself is to use insect spray.

01:45:40Now, Barry sprays himself with this substance before every run and feels safe.

01:45:45But let's have a look at another situation.

01:45:49What if Barry gets attacked by huge dogs?

01:45:52Hey, just kidding.

01:45:53Relax, Barry.

01:45:57Ah, it's a lovely day for a boat ride in the swamp.

01:46:01If not for these mosquitoes, then today would be perfect.

01:46:04But for some reason, the mosquitoes keep getting bigger the further you go into the swamp.

01:46:09They started out as tiny, almost invisible insects, and can now be the size of your thumb.

01:46:15You can hear their buzzing as they whiz past you.

01:46:18You go deeper to investigate why they're so big.

01:46:21Eventually, you see a large cluster of mosquitoes the size of your hand buzzing around.

01:46:27They notice you and start flying towards you.

01:46:30You grab a branch and start swatting them away.

01:46:33You run back to your boat and try to escape, but they follow you, and some manage to land on you.

01:46:39You swat them away, but more mosquitoes pop out of nowhere the size of a basketball.

01:46:45You start your boat and speed your way back to the mainland.

01:46:48As you arrive, you see everyone running away in a frenzy, panicking because of the giant mosquitoes.

01:46:55Some of them are as big as a large dog.

01:46:58People are ducking under picnic tables, while some are running back to their cars and driving away.

01:47:03You get off the boat and run toward the closest grocery store, along with dozens of people.

01:47:08The employees lock up the gates, but the large glass panels show the mosquitoes multiplying.

01:47:14They're getting bigger and bigger until you can see one as big as a car zipping by.

01:47:19It's so strong that it landed on an empty car and crushed it.

01:47:23Everyone inside is ducking away out of fear.

01:47:26You try to calm everyone down and not make any noise.

01:47:29The mosquitoes are landing on the glass panel, blocking out the natural light.

01:47:34It's getting dark inside.

01:47:36Someone turns up the volume on the TV to the breaking news.

01:47:40Mosquitoes are flying rampant all across the continent, destroying natural resources and infiltrating cities.

01:47:47People are advised to stay indoors until further notice.

01:47:50The mosquitoes notice that there are people in the store, so they try to get in by force.

01:47:55A car-sized mosquito flies around in the sky, unaware of what's happening below.

01:48:01Everyone hears some noise coming from the back room.

01:48:03The employees realize they didn't lock the doors.

01:48:07A large mosquito enters and knocks down everything.

01:48:11Everyone runs around in a panic while throwing random stuff at it.

01:48:15Some people grab a fire extinguisher and spray it until it flies to the back room.

01:48:20Some employees lock the door and barricade it so that nothing can enter.

01:48:24Everyone waits nervously.

01:48:26The TV broadcasts some live coverage of how giant mosquitoes are flying everywhere.

01:48:31A helicopter is forced to land because the mosquitoes are flying around wildly in the skies.

01:48:36Everyone shudders when they hear the sound of more mosquitoes buzzing around near the back door.

01:48:43Hours pass, and more mosquitoes keep coming endlessly.

01:48:47There are no people outside, and much of the urban and landscape design in the park is

01:48:51destroyed or overrun by giant insects.

01:48:55Some people eat whatever is available, while some are sleeping.

01:48:58A piece of breaking news interrupts the live coverage and shows that there will be armored

01:49:02buses ready to pick up people near the picnic site.

01:49:06However, the buses won't drive to hot spots since it'll be too dangerous.

01:49:11The only way to get on them is by being on the highway in two hours.

01:49:15Everyone tries to call their loved ones, but the cell towers have been knocked down and

01:49:19no one can call anyone.

01:49:21The mosquito that broke in a while ago destroyed the only landline that was present.

01:49:26People are arguing about whether they should stay or go.

01:49:29More insects cover the only clear patches of the sky until the sun disappears.

01:49:35The people split into two parties, those who are leaving to catch the bus and those

01:49:39who want to stay.

01:49:41The employees know a back way that can quickly lead to the highway.

01:49:45The only problem is that it'll take around 20 minutes on foot, and there are no cars

01:49:49to use.

01:49:50The way is tricky.

01:49:51First, they would need to escape through the main entrance and head through the bushy forest

01:49:56behind the dumpsters.

01:49:58Over there, they can enter a building, possibly through the sewers, which will lead to the

01:50:02lake next to the highway.

01:50:04As the first party decides to leave, they prepare supplies for the breakout.

01:50:09Every second, more mosquitoes arrive, covering the sky.

01:50:13They gear up with anything they can find to protect themselves.

01:50:17Mosquitoes are attracted to the carbon dioxide that people breathe out, and they know that

01:50:21there's a source coming from the grocery store.

01:50:24Once everyone is ready, they get some makeshift torches and light them up.

01:50:28They add some barbecue fuel to keep the fire going.

01:50:31You're part of the party that is planning to escape.

01:50:34The doors open, and everyone makes a break for it behind the dumpster.

01:50:38Many mosquitoes try to attack you, but the smoke from the fire repels them.

01:50:43Every second, more mosquitoes are filling the sky and the environment.

01:50:47Many people end up running back into the store, since they couldn't make it past the dumpster

01:50:51to the other building.

01:50:52Eventually, the rest of the people, including yourself, run toward the building.

01:50:57But it's locked, and no one can break down the door.

01:51:00Option B is to break the glass from a window and crawl inside.

01:51:04You grab a rock and smash the closest window.

01:51:07The only problem is that the mosquitoes can follow you inside.

01:51:11So without any options left, you pull through and run to the basement of the building to

01:51:16find the entrance to the sewer.

01:51:18Success!

01:51:19You've found it, and everyone descends to the bottom.

01:51:22No mosquitoes in sight, just rats.

01:51:25You're walking knee-high in sewer water, with it flowing past you, but it's only a few minutes

01:51:30until you reach the river.

01:51:32Another problem is that the sewer isn't going to the lake, but somewhere deep into the sewer

01:51:37channels.

01:51:38You follow it until you see what looks like an outlet.

01:51:41You make it out, and are near a waterhole where all the discarded sewage leads next

01:51:46to the swamp.

01:51:47The only problem is that you're not next to the highway anymore, and time is running out.

01:51:52More mosquitoes are swarming the air, but they don't bother buzzing next to you.

01:51:56You notice some cat-sized creatures floating on the water.

01:52:00These are baby mosquitoes, or the larvae, and they're coming your way!

01:52:06You and everyone else swim for your lives to the shore.

01:52:09The giant alpha mosquito soars into the air, and swoops down to try and grab someone, but

01:52:15it misses.

01:52:17Everyone makes it to the thick, swampy area where no giant mosquitoes can enter.

01:52:21Everyone covers themselves with branches to protect themselves.

01:52:24It takes 15 minutes until the armored bus arrives.

01:52:27Since the mosquitoes can't enter, this will be the best place to hide until then.

01:52:31Darkness falls, and still, no bus!

01:52:34It's been three hours, and nothing!

01:52:37The mosquitoes are still buzzing around, and everyone is getting uncomfortable under the

01:52:41thick bushes.

01:52:42After a while, everyone hears a roaring engine, and sees lights flashing on the highway!

01:52:48Everyone gets up and runs to the bus, but you stop them to not draw the mosquitoes'

01:52:52attention.

01:52:53You volunteer to sneak out and stop the bus, and then everyone else can follow without

01:52:58drawing too much attention.

01:52:59You move a couple of branches, step over some tree bark, and crawl to the highway.

01:53:05You try to hold your breath so that you won't make any heavy breathing sounds.

01:53:09You reach the side of the road and wave your arms to stop the bus.

01:53:13It pulls over, and the door opens.

01:53:14You signal the rest of the people to follow, and they follow your lead.

01:53:19Everyone is inside and safe.

01:53:21The mosquitoes notice and start pecking on the bus, but the armor is sturdy.

01:53:26The bus drives off, looking for other people along the road, and suddenly, a Goliath lands

01:53:32in front of you!

01:53:33The bus stops, and sees a mosquito the size of a Boeing 747!

01:53:38It looks straight at you.

01:53:39It gets ready to attack, but the bus speeds under its legs and drives off.

01:53:44The mosquito takes off and tries to catch the bus, but you enter a tunnel to the other

01:53:49side of the mountain.

01:53:51After a few minutes, you reach an open area with no trees or buildings.

01:53:55The bus is speeding while dodging obstacles along the way.

01:53:58Finally, you notice you are near the grocery store where you were held up.

01:54:03The bus opens the door for everyone inside to be taken to a safe zone.

01:54:07You hear from the aid workers that the whole world is being overrun by these giant creatures.

01:54:13As you drive along, you see a hybrid mosquito that has two heads and a scorpion's tail!

01:54:19It's as tall as a Statue of Liberty, and it's ready to attack!

01:54:23Whatever is causing these mosquitoes to grow abnormally is also making them into hybrids

01:54:28and mutants!

01:54:29And you thought it was going to be a good Monday!

01:54:32That's it for today!
