00:00 Tonight, the biggest and fiercest shark in history will face the blue, a mysterious creature
00:06 from the ocean depths.
00:08 The fight takes place far out at sea, so people are not in danger.
00:13 But if Megalodon loses, the life of all mankind may be at risk.
00:18 But first, let's get to know our opponents better.
00:21 Megalodon was an ancient marine predator, a giant shark feared by all aquatic life for
00:26 millions of years.
00:28 Megalodon had no competitors in the oceans.
00:31 It was at the top of the food chain.
00:33 Current sea inhabitants don't even realize how lucky they are, because this monster went
00:38 extinct about 3 million years ago.
00:41 Although people can't know for sure if it's really gone.
00:45 The ocean is only 5% explored.
00:48 It's possible that somewhere in the depths, Megalodon still terrifies all the fish.
00:53 And today, the colossal shark will fight against a worthy opponent, the blue.
00:59 Technically that's just the name of the sound, the sound that oceanographers recorded in
01:03 1997.
01:04 The creature that made it could be called a sea monster, a kraken, a beast from the
01:10 deep.
01:11 No one knows how it looks, but we can guess its size.
01:17 This ultra-low frequency blue was so powerful that it could be heard by special sensors
01:22 3,000 miles away.
01:24 If you were in New York, you could listen to the sound from Los Angeles.
01:28 But the sound was deep underwater where the audibility is actually much worse.
01:33 A creature that can make such a sound could be dozens of times bigger than a blue whale,
01:38 the largest animal living in the world.
01:40 Interestingly, the source of the sound is located near the most remote place on Earth,
01:45 Point Nemo.
01:46 It's located more than 1,000 miles off the coast of the three nearest islands.
01:52 This place is one of the most poorly studied on our planet.
01:55 Point Nemo is used by many companies as a space garbage dump because of the long distance
02:00 from land.
02:01 Every year, satellites fall there.
02:04 But the worst thing is that the coordinates of the fictional ancient city of R'lyeh
02:08 are near Point Nemo.
02:10 That city was described in the books of author H.P.
02:12 Lovecraft.
02:13 Among the ruins of R'lyeh, the monster Cthulhu lives.
02:17 Yeah, it sounds nothing like it looks.
02:20 Hey, neither do I.
02:21 Hey, Cthulhu, buy a vowel, will ya?
02:24 Man, it's like a cat walked across the keyboard, and there's your name.
02:28 This is an entirely fictional creature, but many people think it could be the source of
02:33 the bloop.
02:35 The chances of the megalodon winning are small because Cthulhu is a demigod.
02:40 It has arms and legs, wings, and a head resembling a colossal octopus or clam with dozens of
02:47 long tentacles.
02:48 It's impossible to determine Cthulhu's size, but if you believe the records of writers
02:53 and drawings, its size can reach up to 300 feet in height.
02:57 The megalodon is 5 times smaller at about 60 feet, or slightly less than one subway
03:02 car.
03:03 Ooh, a nice lunch for a monster shark!
03:06 The shark weighs about 100 tons, like two tanks.
03:10 The weight of Cthulhu is also unknown, but we can say with confidence that it can easily
03:15 lift two tanks with its hands.
03:18 But Cthulhu can change its size and shape at will.
03:21 It can be anybody, from the size of a human to the extent of a continent.
03:26 Also Cthulhu can spawn any number of limbs.
03:29 But let's not stray too far into fantasy, otherwise Megalodon won't stand a chance to
03:34 win.
03:35 Let's say Cthulhu has a constant size.
03:38 So in size, Megalodon loses to its opponent.
03:42 Cthulhu is an ancient wise being that is more than a million years old.
03:46 It has secret knowledge and telepathy.
03:49 Megalodon is primarily an animal that simply follows its instincts.
03:53 One of the main advantages of any match is intelligence.
03:56 So Cthulhu wins against the giant shark again.
04:02 Lovecraft described Cthulhu sleeping for many millennia and waiting to awaken to start an
04:07 apocalypse.
04:08 Therefore, all people in the world are interested in a Megalodon victory.
04:13 To support the shark, people send their ships to help.
04:16 It's a bit unfair, but even now Cthulhu wins.
04:20 The monster can control people telepathically.
04:23 It gives an order to every sailor's brain and all the ships sail away from the battlefield.
04:33 Within the ocean waters, somewhere in the southern hemisphere, a ghostly black shadow
04:38 looms deep down in the depths.
04:41 Suspiciously swimming far below, the Megalodon is hunting for its next meal.
04:48 With the appearance of a great white shark, but three times the size of the largest ever
04:53 recorded, its intimidating design has evolved over millions of years, creating the ultimate
04:59 natural predator.
05:01 For millions of years, the intimidating evolutionary traits have gone unchecked and unopposed.
05:07 With its keen senses, it detects its prey within three miles.
05:13 As it swims below, it's been following an unsuspecting sea turtle that's slowly paddling
05:18 above on a long voyage.
05:20 The Megalodon stalks the turtle, ensuring it makes its move toward the turtle at the
05:25 right moment.
05:26 Swimming upward at 11 miles per hour, intending to immobilize the turtle by ramming it.
05:32 As it approaches, the Megalodon's adept senses notice something else lurking nearby.
05:38 Pausing its pursuit of the turtle, it adjusts and turns to face another, much larger object.
05:45 The Megalodon may be the largest marine predator to have ever lived on Earth, rightfully feared
05:50 by all creatures within these waters, but not today.
05:54 There is a newcomer to these parts, one that has a similar reputation and matches the Megalodon
06:00 in ferocity.
06:01 This unknown creature intends to contest these hunting grounds.
06:05 The challenger is the Leviathan.
06:09 As the sea turtle takes this opportunity to swim away as fast as it's able, these two
06:14 apex predators size each other up from a distance, preparing to establish who will reign as the
06:20 supreme king of the sea.
06:23 The Megalodon dominated the ocean sometime between 3 to 23 million years ago, spreading
06:28 to all corners of the globe, within seas surrounding Europe, Africa, the Americas, and Australia.
06:36 Its focus is mainly on offshore areas where prey would be prominent.
06:40 Hunting sea turtles, whales, seals, dolphins, and other sharks, its range was long, traveling
06:46 between coastal and oceanic waters throughout different stages of its life cycle.
06:52 Given that the territory they cover grows with each year they live and the wide range
06:56 of prey available to them, the Megalodon's size can reach up to 67 feet in length.
07:02 Armed with thick and robust teeth made for grabbing their prey and biting through bone,
07:07 they have a 41,000 pound bite force, which is almost four times stronger than that of
07:12 a T-Rex.
07:14 Their tactics include ambushing their prey from below while ramming them into submission.
07:19 With larger prey, they aim to disable them by biting at the fins and, once immobilized,
07:24 biting through their chest.
07:26 Their jaw is made up of around 276 frightening serrated-edged teeth that are 7 inches long
07:33 and jagged at the sides.
07:35 The Megalodon's competitor, the Leviathan, is armed with 22 large teeth of its own that
07:41 come in various sizes, some up to 12 inches long.
07:45 All are capable of piercing through its target, excluding tusks in comparison.
07:50 These are among the largest teeth that have ever existed on any known animal.
07:55 Although it hasn't reached an overall equivalent size to the Megalodon, its length is equally
08:01 impressive as it's capable of growing as large as 57 feet long.
08:06 Mainly living within the Southern Hemisphere, they've only been around for a short while,
08:11 existing from 9 to 10 million years ago.
08:14 Although it hunts similar prey to the Megalodon, it has a different strategic method of hunting,
08:19 chasing its prey, tiring it out to the point of exhaustion, and then finishing it off by
08:25 ramming it with its head and then biting it.
08:29 It also has a more adaptive trait in its arsenal, its much larger brain.
08:34 Being a warm-blooded mammal, it possesses superior intelligence, ensuring quicker thinking
08:40 with the ability to change its tactics at crucial moments.
08:43 The Megalodon acts on sheer instinct, and that has worked consistently for the past
08:48 few million years, but will it work now?
08:53 Although there are millions of years of difference between when these two behemoths existed and
08:57 patrolled the seas, they shared a short period of time in history, but when they did overlap
09:03 one another's territory, they created some of the most epic conflicts that have ever
09:07 been had on Earth.
09:10 This Megalodon's turf has never been in contention, until now.
09:15 As the Leviathan approaches, observing the much larger Megalodon, it's hesitant to make
09:20 the first move, as generally, anything that it has come across before attempts to escape
09:25 immediately, causing a chase to begin.
09:28 The Megalodon, however, never flees.
09:31 The Megalodon's instincts ensure it will act overconfident, and, as expected, it makes
09:37 the first move.
09:38 It swims at full speed, gliding through the water, aiming to ram the Leviathan.
09:44 The Leviathan has no other choice but to do the same, rather than turning to flee and
09:48 leaving itself unprotected.
09:51 The two aquatic giants slice through the water, on their way to meet fin to fin.
09:56 The Megalodon is puzzled that its foe is not turning tail to swim away, but it continues,
10:01 as it has no reason to doubt victory from this tried and true tactic that has never
10:05 failed before.
10:08 As the Megalodon approaches, it quickly turns to swim downward.
10:12 Swims faster and more agile than its opponent, it maneuvers below, gaining some distance.
10:17 The Leviathan moves much slower, and is unable to turn in time, as the Megalodon veers upward
10:23 and rams it on its soft underbelly, attempting to force it into submission.
10:29 There is little effect due to its size, and the Leviathan continues to turn, but it's
10:34 far too slow, as it attempts to bite with a desperate hope to grasp its attacker with
10:38 its powerful jaws.
10:40 The Megalodon easily swims away from its toothy trap, quickly retaliating by taking aim at
10:46 the tail and fins, chipping away at little pieces as it bites, then quickly retreats,
10:52 continuing this routine over and over, trying to disable the Leviathan's defenses.
10:57 This tactic is effective, but it's taxing on the Megalodon, as it's running out of energy.
11:02 Still, it pushes hard to try and finish the hunt.
11:06 Hey, let's take a deep dive into ocean waters to see which of these creepy-looking animals
11:12 are our friends!
11:13 We're swimming in the tropical waters of Nanyabalava Island near Fiji.
11:19 Can you see those giant creatures the size of a Volkswagen Beetle?
11:23 Those are manta rays.
11:24 They've got a long, whip-like tail and large, flat diamond bodies.
11:29 There are two species of manta rays – the reef manta ray and the giant manta ray.
11:34 They belong to the same family as sharks, but they only have small teeth in their lower
11:39 jaw.
11:41 They feed on zooplankton, tiny fish, and crustaceans.
11:45 Manta rays are social animals, and they like people.
11:48 Once you let them come close to you, they'll swim around you to observe you.
11:52 Don't chase them, though, because they're super-fast swimmers.
11:56 Their name translates to "cloak" or "blanket," and out of all sea creatures,
12:01 they've got the largest brain compared to body weight ratio.
12:05 These fellas can recognize themselves in a mirror!
12:09 The Asian sheephead wrasse follows.
12:12 Even if it seems unsightly, it's one of the friendliest fish you'll come across
12:16 in the shallow waters of Japan, China, and Korea.
12:20 It has protrusions on both its jaw and head.
12:23 It likes to hide in its anemone, and it's usually scared to go out even at 40 inches
12:28 long.
12:30 One of these fellas developed a friendship with a Japanese scuba diver 30 years ago.
12:35 When the diver found the fish, it was injured, and he helped it recover.
12:39 The diver had been the caretaker of an underwater Shinto shrine.
12:43 He calls the fish by hitting the underwater bell.
12:48 Time to go swimming with the largest fish in the world, the whale shark.
12:52 Though these creatures are sharks, they have a lot in common with whales.
12:57 They can live for 100 years, though they've got tiny brains.
13:01 They're indifferent to humans.
13:03 These fellas don't care about anything they can't eat.
13:06 And unlike other shark species, they won't bite you.
13:09 Whale sharks are filter feeders.
13:11 They do have teeth, 3,000 of them, but they don't use them.
13:16 They've got a massive mouth, like me, but their throat is only the size of a quarter.
13:22 Next we have the sunfish, a fish without a tail that looks like it's been cut in half.
13:28 It has large fins, and when you see it breaching on the surface, you'll think a shark is
13:33 approaching.
13:34 The sunfish dives deep in the water to let other fish exfoliate its skin and remove parasites.
13:41 Once they're done, it returns to the surface to sunbathe.
13:44 It's also a voracious eater.
13:47 If it sees you in the waters, it'll likely approach you and observe you.
13:51 Within a day, you'll be able to feed it from the palm of your hand.
13:56 Time for the animal that looks like it's always smiling – the bottlenose dolphin.
14:00 It's one of the most social sea creatures, and it travels in groups.
14:04 It enjoys playing, hunting, raising calves, and helping out its community.
14:10 Bottlenose dolphins are excellent swimmers with speeds reaching 19 mph.
14:15 They usually come up to the surface to breathe air through the blowhole on their head.
14:19 These creatures are great communicators, and they send messages to each other.
14:23 They use echolocation to navigate and find food.
14:27 When they spot people, they become very friendly – so much that they let their guard down,
14:32 and it makes them vulnerable to other sea creatures such as sharks.
14:37 Heading to the Pacific coast, we'll come across some gray whales.
14:41 Their skin is covered with parasites and other organisms that make their snouts look like
14:46 rough pieces of rock.
14:48 You gotta get on their nice side first.
14:50 Gray whales can attack a large boat, a ship, or a vessel if they sense their calves are
14:55 in danger.
14:56 But, generally, they're friendly and appear unbothered by rowing kayakers.
15:01 In some cases, they'll approach small boats and allow humans to touch them, though you're
15:06 required by law to keep your distance.
15:09 If it wants to get closer, it will.
15:11 If it feels threatened, it will act aggressively.
15:15 Let me show you a fish with a tool on its head – the hammerhead shark.
15:20 Their skull helps them with hunting.
15:22 Their eyes are placed on the hammer's outer edges and gives them a 360-degree vertical
15:28 view.
15:29 But they've got a blind spot in front of their nose.
15:33 Their heads are like metal detectors.
15:35 Most of what they want is below the sand's surface.
15:38 So they lightly dip their heads in the sand and sweep up whatever is under there.
15:43 You'll see them in temperate and tropical waters both near the shorelines and offshore.
15:49 They usually move in groups.
15:50 They're mostly harmless to humans and divers, but there have been a few occasions where
15:55 they got aggressive.
15:56 But before they do, they'll give you a bunch of warning signs, and divers know how to handle
16:02 them.
16:03 I'll show you something kinda smaller – the sea lion.
16:07 These creatures are a bit tricky.
16:09 They're playful, aggressive, arrogant, smart, and above all, curious.
16:15 Sea lions can't breathe underwater, but they can dive almost 1,000 feet deep, and
16:20 they can hold their breath for a long time.
16:23 They take in air through their nose, and once they dip their heads in the waters, their
16:27 nostrils slam shut.
16:29 If they spot humans at the beach, they'll stay away and wait for them to leave.
16:34 Wild sea lions aren't the friendliest to anyone, especially if they feel threatened.
16:39 The approachable ones have been trained in captivity.
16:43 Beluga whales are next.
16:44 They're white with bulgy heads, and they're amongst the most social and loudest you'll
16:49 ever meet.
16:50 Their upwards-facing mouths make them look like they're smiling.
16:54 When beluga whales are born, they're a dark gray shade.
16:57 It takes 8 years for their skin to turn white.
17:01 They can change the shape of their heads by blowing air around their sinuses.
17:06 Beluga whales love humans.
17:08 Once they make human friends, they don't want to leave.
17:11 Even though they're wild animals, they become too entrusting with people.
17:15 Marine biologists suggest staying away for their safety.
17:20 The Stonefish Stonefish aren't going to win any beauty contests,
17:26 unless the pageant is for best rock look-alike.
17:30 Their tiny unreflective eyes and rough skin blend in perfectly with their environment.
17:35 A large head, an even bigger mouth, and a home full of, yeah, it's rocks.
17:41 And just 'cause you're on the beach doesn't mean you're safe.
17:45 Stonefish can survive for 24 hours out of the water.
17:49 Stepping on one, or even handling one, won't be that fun.
17:53 Their dorsal fin spines have extremely strong venom.
17:56 It shoots out when they get stepped on, and can lead to paralysis or even heart failure.
18:02 You'll need help fast.
18:04 No wonder they're one of the most dangerous creatures in the water, or anywhere.
18:08 Be careful when scrambling around rocky areas.
18:11 They love to play hide and seek.
18:15 The Deep Sea Dragonfish If there were a prize for the most hideous
18:20 fish in the ocean, the deep sea dragonfish would win.
18:24 With slimy, scaleless skin, massive teeth, and a face only a mother could love, this
18:30 bad boy of the sea is nothing to mess with.
18:33 It likes to swim between 700 feet and 6,000 feet below the surface of the ocean, where
18:39 the waters are the darkest and coldest.
18:42 Along with some other creatures on this list, the deep sea dragonfish relies on its bioluminescent
18:47 body parts to catch prey.
18:50 It also uses its hanging appendage, which boasts a little red light on the end, coming
18:55 out from its lower jaw.
18:57 Many fish mistake this little light for prey, luring them right into the jaws of the deep
19:02 sea dragonfish.
19:04 Very clever, dragonfish, very clever indeed.
19:09 The Fangtooth The Mariana Trench is an underwater trench
19:14 with a depth of 35,000 feet, nearly 7 miles below the ocean's surface.
19:20 Let that sink in.
19:22 While scientists know the Mariana Trench exists, it's one of the least explored places on
19:27 Earth.
19:28 It's also the deepest area of Earth's oceans, and although many creatures down there probably
19:33 haven't even been seen by humans yet, scientists have had the creepy pleasure of getting to
19:39 know the Fangtooth.
19:41 The Fangtooth fish shamelessly lives up to its name.
19:45 Just look at that thing.
19:46 The Fangtooth is carnivorous and feeds on just about anything it can find that gets
19:51 caught in its sharp-toothed mouth.
19:54 These fish rely on their "contact chemoreception" to find prey.
19:59 In other words, they can sense chemical residue that comes off of other living organisms in
20:03 the deep sea.
20:05 This is because they don't have any light-producing cells on their bodies, unlike many other deep
20:10 sea fish.
20:11 On top of all that, it's pretty dark down there, so whatever crosses their path, they
20:16 chomp on.
20:18 While these guys look pretty scary, they're not a threat to humans.
20:22 They only grow about 7 inches long.
20:25 Even so, I wouldn't want to run into one of these things during a relaxing swim in the
20:29 ocean.
20:31 The Dunkleosteus.
20:34 Strangely enough, this prehistoric fish, known as the T-Rex of the seas, had no teeth.
20:41 Those were replaced with bony plates that allowed it to have the strongest bite among
20:46 other monsters of its size.
20:50 The Goblin Shark.
20:52 If you thought the movies about sharks were scary, this next deep sea creature will make
20:57 you swear off going for dips in the ocean forever.
21:00 However, it lives 3,000 feet underwater, so you'll never likely see it face to face.
21:07 The Goblin Shark looks like a cross between a shark and a creature from your worst nightmare.
21:13 These sharks boast a protruding, sword-like snout with a jaw that juts out to match.
21:19 Unlike other sharks that have more of a gray hue, this creepy thing looks not so pretty
21:24 in pink.
21:26 Aside from their scary demeanor, what do scientists really know about the Goblin Shark?
21:31 Well, not much, except that they can grow up to 18 feet in length.
21:36 Looks like there's still a lot to learn about these guys, if you dare to.
21:42 By the way, did you know that sharks don't sleep?
21:45 Many species have to keep water moving over their gills to get oxygen, so they can't
21:50 fall into a deep sleep like we do.
21:53 That's why they stay half-awake during rest.
21:56 Typically, sharks don't even close their eyes.
22:00 The Cookie Cutter Shark.
22:04 This shark is a living horror, with lower teeth being big and sharp, while the upper
22:09 ones are much smaller.
22:11 When its teeth fall off, the shark eats them to maintain calcium levels.
22:16 Pretty smart solution for a shark.
22:19 The Frilled Shark.
22:23 Studying the Frilled Shark is like looking through a portal back to prehistoric times.
22:27 That's because scientists think that these eel-like sharks haven't changed much since
22:32 their oldest ancestors roamed the deep sea waters, so they're sometimes referred to
22:37 as "living fossils."
22:39 These sharks' mouths are filled with a terrifying 25 rows of backward-facing sharp
22:44 teeth.
22:45 300 in total!
22:47 They're designed to grasp prey and hold them tight so they can't get away, according
22:52 to early studies of the shark conducted in 1884 and published in the Bulletin of the
22:58 Essex Institute.
23:00 Luckily for swimmers, the Frilled Sharks live between 390 feet and 4,200 feet below the
23:06 ocean's surface, so they'll probably never run into them.
23:11 Probably.
23:12 This is probably the worst nightmare of any dentist!
23:15 The Northern Stargazer.
23:19 Take a look at this cutie!
23:21 The Northern Stargazer is definitely not something you'd wish to see on the ocean floor.
23:26 This horrid creature hides its body under the sand, leaving its face above to wait for
23:31 prey.
23:32 That's it for today!
23:33 So hey, if you pacified your curiosity, then give the video a like and share it with your
23:38 friends!
23:39 Or if you want more, just click on these videos and stay on the Bright Side!
