00:00Look at this funny african rat.

00:03Oh, he looks so cute.

00:05Well, you're wrong.

00:07He has an asset in his sleeve.

00:09His poison.

00:10To be honest, the only known toxic rodents in the world are these rattlesnakes.

00:15When they feel tickled, they inflate their fur and show off their black and white stripes.

00:21Right in the middle, there are a bunch of special brown hairs with an alveolar texture.

00:26These are not only decorative,

00:29they are full of such a violent poison that they could kill an elephant.

00:33Rats use it as a chemical armor to protect themselves from predators such as hyenas and wild dogs.

00:41East Africa has long known the toxicity of the rattlesnake.

00:46In 2011, researchers discovered that these rats were pulling poison from a certain tree.

00:51Only a captive rat was able to be surprised while performing this poisonous ritual.

00:56At first, we thought it was an isolated fact.

00:59Nevertheless, the researchers continued to observe it.

01:02The team had 25 rats.

01:04They were filmed in a laboratory before proving that it was not a singular fact.

01:09Even if we know them well, these rats apparently have some weak points.

01:13Some of them seem to be more focused on monogamy, or even the sharing of parental tasks.

01:19Monogamy is rare in the animal world, but it is rat practice.

01:23It's pretty fascinating.

01:25But the researchers claim that they need to do more research before confirming the family values of these rodents.

01:32The next on the list is the lorillant.

01:35This creature seems to be the embodiment of everything that is cute, with its small size and its big eyes.

01:41But these animals are not really of the cuddly kind.

01:44And worse, they are the only venomous primates on the planet.

01:48They live in the tropical forests of the south and southeast of Asia.

01:52You may be wondering why they are called lorillants.

01:56When the explorers first encountered them in the 18th century,

02:00they thought that these little creatures were as slow as lazy people.

02:05Of course, they can stay still for hours and move slowly.

02:10But don't be mistaken.

02:12They are perfectly capable of handling themselves when the need is felt.

02:15If you look closely, you will notice an overgrown and overgrown spot on the inside of their forearms.

02:21This is the brachial gland.

02:23And it secretes a seriously nauseating oil.

02:26When the lorillants feel threatened, they lick this gland,

02:30mixing their saliva with this oil to create a venomous solution.

02:34And when they bite another animal, this venom penetrates directly into the enemy's blood system.

02:39This bite is quite cruel.

02:41It is capable of killing small animals and other insects and causing serious problems in humans.

02:47Suddenly, these big eyes no longer seem so innocent.

02:50In the world of lorillants, males fight for females.

02:53Females fight to protect their young.

02:55And everyone fights to defend their territory.

02:58This venom is useful in such confrontations.

03:01Here, the mothers use their venom cleverly.

03:04Before going out to look for something to nibble on,

03:06they lick their brachial glands and bathe their babies.

03:09This transfers the venom to the fur of the young

03:12and acts as a warning for potential predators.

03:15The next animal is the sand cat.

03:17Meow, this kind of cat lives in the desert.

03:20Unlike other cats, they have made this environment their home.

03:25To begin with, they have the ultimate shoes to walk in the desert.

03:29A thick fur on their paws and even between their toes.

03:33They also enjoy an integrated isolation against extreme temperature variations,

03:39from 50 degrees during the day to 0 degrees at night.

03:44They even grow winter coats,

03:46whose hairs can reach 5 cm long.

03:51Sand cats can spend weeks without drinking a single drop of water.

03:55They draw all the water they need from the prey they nibble on.

03:58In terms of hunting, these sand cats, apparently so cute,

04:02unleash the predator sleeping in them.

04:05Forget their adorable cat aura, these felines are ferocious.

04:09They are not difficult to feed either,

04:11and feed on small rodents, birds or insects.

04:15Oh, and they even prey on venomous vipers.

04:18In addition, if they get more than they can eat,

04:21they hide their extra food in the sand for a small midnight snack.

04:26Their secret weapon is an extremely thin web.

04:30They do not leave footprints and make no noise when they approach their prey.

04:36Here is a sea conch, a kind of sea snail, but with a twist.

04:41They have vivid and colorful patterns on the surface of their shells.

04:45And they are not only pretty to look at, they also have a formidable venom.

04:50Armed with an adapted radula and a venom gland,

04:53sea conches are among the most acquired hunters in the oceans.

04:57They use this tooth, similar to a harpoon,

05:00to project a venomous attack on their prey, paralyzing it before eating it.

05:05Speaking of venom, that of sea conches is the same as a cocktail.

05:09It contains a mixture of toxins with different effects.

05:13Some of the largest species of sea conches can inflict a sting that is not only serious,

05:18but can even be fatal to humans.

05:20However, their venom also helps us solve some medical problems.

05:24A fifth relatively cute animal, albeit dangerous, is the millipede.

05:29These creatures have two pairs of articulated legs on most segments of their body.

05:34Each of these two-legged segments is made up of two simpler segments that combine.

05:39Imagine a team with an elongated, cylindrical or flattened body,

05:43generally comprising more than twenty segments.

05:46But millipedes are the shortest rebels in the band,

05:50which allows them to roll in tight balls.

05:54In 2021, a new species was discovered that had more than 1,300 legs.

05:59If you dive into the world of myriapods, you will find about 12,000 different species.

06:05Many of them are generally harmless to us, but be careful.

06:10Some of them could well be in your house or your garden.

06:16The sixth animal is the pitohui bicolor.

06:19It is a bird found in New Guinea.

06:21It stands out as one of the rare birds known for its toxicity,

06:25with poison in its skin, feathers and other tissues.

06:29This toxin comes from its diet and serves as a defense against predators and parasites.

06:35It is interesting to note that the resemblance it maintains with other toxic pitohui

06:40is a perfect example of converging evolution.

06:43When unrelated species develop similar traits due to comparable environmental pressure.

06:49In this case, different toxic pitohui independently developed similar traits as a form of protection.

06:56The pitohui bicolor also has a mullerian mimicry.

07:00It is a phenomenon during which harmful or venomous species evolve to resemble each other.

07:05In simpler terms, it is like a group of toxic friends who would all dress the same

07:10so that everyone knows that it is better to avoid them.

07:13In addition, non-venomous species imitate the appearance of the pitohui bicolor

07:18in a phenomenon known as Batesian mimicry.

07:21It is when harmless or less dangerous species evolve to resemble a more ferocious or toxic species

07:28in order to enjoy the same protection against predators.

07:31In this case, other birds reproduce the appearance of the pitohui bicolor,

07:36although they do not have the same defenses.

07:39Thus, an harmless bird wears a venomous costume to ward off potential threats.

07:45Ornithorhynchs have an adorable look with their thick fur and their duck beak.

07:50But you don't want to rub yourself with them either.

07:53Especially at the end of winter, when the male ornithorhynchs become a little aggressive.

07:57They fight for the females and use the vicious ergos on their legs

08:02to inject their venom during the confrontation.

08:04In 1801, a biologist thought that these spurs were used to keep the females in place during mating.

08:10But he was wrong.

08:11These creatures are more interested in insect larvae than in any romance.

08:15However, the end of winter is a whole other story.

08:19Males fight, inject their venom and the losers are paralyzed.

08:23There have been cases where they were even caught by humans.

08:27But fortunately, none of them were deadly.

08:29If an ornithorhynch decides to bite you, even morphine will not relieve the effects

08:34and doctors may need to remove the spurs from your wound by hand.

08:38Ouch!

08:40Also pay attention to globefish.

08:42They may be adorable, but they are the second most toxic vertebrae in the world.

08:47Their liver, their eyes and sometimes their skin contain tetrodotoxin.

08:52It is a substance that gives them an infected taste and can be deadly to fish.

08:56They also pose a serious threat to us,

08:59because this toxin is up to 1,200 times more violent than cyanide.

09:04A single globefish contains enough toxins to kill about 30 adults

09:08and there is no known antidote.

09:10Despite this danger, some Japanese consider the flesh of the globefish as a refinement,

09:15called fugu.

09:18The chefs trained to this effect are perfectly aware that a slip of the tongue

09:22could easily shut down their shop.

09:24This is why not everyone is allowed to prepare this dish.
