The shark opens its jaws wide and is getting ready for another bite when something long and gnarly hits it on the side a smack powerful enough to make it close its mouth and struggle to keep its balance in the water the megalodon's eyes open wide in surprise it turns around looking for the enemy but too slow .
Another strike lands on its gills beating the breath out of its mouth in a swarm of bubbles at the last moment though the shark notices the direction of the attack it's coming from below regaining its senses the beast turns its snout down sharp and hurls itself through the water like a torpedo right underneath it sees a hazy silhouette but .
Can't discern its shape yet it's enough for the meg however it's locked on the target a creature foolish enough to mess with the ocean king it opens its mouth showing rows of huge crooked teeth and rushes the enemy but just as it comes down on the foe it lurches to the side and the shark snaps its jaws in the empty water in rage now .
It turns to face the impudent critter and manages to take in right before receiving another crushing blow to the spine going down dazed the megalodon watches as a squid the size it's never seen before stretches its many limbs in all directions two of those are much longer than the .
Rest and the monster raises them to its colossal head then it turns with its side to the shark and the mag finds itself looking right in the eye as big as a manta ray and as black as the deepest abyss the shark is petrified for a moment but comes around just in time to see yet another strike from one of those long .
Tentacles it comes straight from above and the mag quickly shifts to the side to avoid the beating the spindly thing swishes inches from the shark's head leaving a trail of bubbles as the kraken reels the limb back to its head the megalodon sees the opportunity and strikes back its jaws close on the .
Tentacle ready to rip it off but something's not right the thing is rubbery and the shark's teeth can't even puncture it still it clenches its jaws even tighter and feels the monster squid writhing to break free realizing that it can't tear at the limb the mag starts pulling it turns away .
From the kraken but this time it's not fast enough it forgot about the second attacking tentacle and gets hit hard on the side again the impact makes it release the limb but it's too angry to feel any pain the beast turns toward its nemesis and launches itself forward aiming at that giant eye with its snout .
Yet the kraken reacts lightning fast it spins in place turning to meet the oncoming hunter with all of its tentacles closed and interwoven like a living shield the megalodon hits the writhing mass at full speed and is deflected to the side without losing momentum it makes a smooth turn and propels itself at the .
Enemy from the other side this time the squid isn't able to protect itself all 60 tons of the megalodon hammer at the side of the kraken's head it's also rubbery and malleable but the monster is obviously dazed by the impact it lulls to the side and starts sinking elated by its success the megalodon .
Continues the onslaught and opens its jaws again to snap them on the creature's head but the squid suddenly swoops around and the meg finds itself in a tangle of tentacles shorter but thicker and much stronger than the two clubbing ones it thrashes trying to break free but the limbs are covered with large suction .
Cups nothing captured by them can get away the mass of tentacles unravels and the meg sees the enormous beak in front of its eyes just a dozen feet away it isn't big enough to swallow such a huge prey but the limbs bring the shark towards it anyway as a last resort the megalodon decides .
To headbutt the kraken's beat in a fluid motion it beats its tail and propels itself forward teeth clenched the squid didn't expect the attack and only just manages to close its beak when the shark snout connects with it a loud thud and the kraken is pushed back hard releasing the meg from its grasp the suction cups pop from the shark's .
Body leaving uneven trails of round scars the meg pursues the enemy before it comes around and tries to bite it again but too late the kraken turns over and starts scampering away at a great speed the shark doesn't let on though and accelerates it sees a whirl of tentacles before it as the squid goes deeper into .
The dark parts of the ocean and then it suddenly loses all side of the monster all side of everything in fact in a mere instant all the shark can see around is pure darkness or still it can't smell anything the megalodon looks around frantically trying to catch any movement and then sees bright sparks and goes down as two .
Powerful tentacles at once strike its back the giant squid had let out a massive cloud of ink but instead of escaping it used the cover to regroup and attack the mega shark from behind it worked the meg is dizzy and can't seem to find its bearings the kraken uses the opportunity to try .
And finish the business it starts flailing its long attack limbs beating the shark without giving it a single moment of respite but the meg surprisingly becomes enraged with the assault and starts snapping at the tentacles hitting it from every direction it misses once twice but on the third attempt it manages to catch .
One of the limbs in its monstrous teeth knowing it can't pierce through the rubbery texture of it the shark begins pulling right away it turns straight up to the surface and uses all its remaining strength to drag the protesting squid with it the kraken continues beating its enemy with its one remaining tentacle but to .
No avail the meg seems to be too intent on getting to the surface the beast is terrified its habitat is deep and dark while shallow waters are the megalodon's domain yet it can't do anything but watch those gigantic eyes becoming even larger as the monster shark hauls it to the blinding sun above .
Finally the meg breaks the surface tentacle and mouth the weight is too heavy for it to leap high but the speed and momentum is enough to fling the squid upwards the shark lets go of the squishy limb and immediately dives back down pummeling the kraken with its tail on the way .
The huge body shutters and appears on the surface but then dives too only to see a lunging form of the mag closing in on its bell-shaped head luckily the aim was not very precise and the squid is only grazed by the sharp teeth but the beasts had enough it waits for the meg to come at it again and lets out another clot of ink the .
Shark is disoriented and the kraken speeds down down into the cozy dark depths of the ocean it won't become anyone's dinner tonight as the ink dissipates the megalodon looks around and sees nothing but empty ocean the squid is gone glass sponges are weird little creatures that sit in one place for thousands of .
Years from their favorite spot under the sea they witness the first europeans crossing over to the americas they can live up to fifteen thousand years and what's even cooler is that they can control their aging process speed it up or slow it down they have a glass-like exoskeleton for .
Protection lobsters can grow back a limb if they lose it and they're basically immortal they produce an unlimited number of enzymes that keeps their dna young forever and they just keep on growing that means they outgrow their own shells they have to shed their exoskeleton every now and then and upgrade to a .
Bigger one the largest lobster ever caught was 44 pounds off the coast of nova scotia scientists think this large lobster was around 100 years old it was around when edison invented the phonograph this next creature is a mix between a jellyfish and a tree branch each end of the hydra has a ringed foot .
And it spends its days chilling by lakes and rivers its tentacles grab onto tasty snacks that swim past it so what's the secret to its immortality that's something everyone wants to know the hydra has the ability to renew its stem cells scientists have been trying to do that for years they can actually slow down their aging process .
Now these little sea creatures are red sea urchins they sit on seaweed in shallow waters and are immortal well we haven't been studying them long enough to know for sure but scientists say they only grow in size not an age what well they sort of stay like little baby urchins but grow in size adult baby urchin okay .
These little babies can reach around 100 years old even 200 the slowest on the list the giant tortoise it can reach 200 years old and one of the oldest is jonathan he's technically the oldest crawling land animal he was born in 1832 and lives it up on a remote island called saint helena jonathan's been through a lot .
He's seen the very first american skyscraper the eiffel tower oh yeah he's also lived through every single world series starting when he was 71 years old now he can't see too well and he's lost his sense of smell but he's still going strong back to the oceans and the greenland .
Shark it's been known to be the longest living vertebrae and can live more than 400 years swimming around for that long in the deep dark cold ocean means these sharks are tough they're able to withstand insane water pressure sharks are one of the only creatures today that haven't been affected too .
Much by evolution many sharks have been around since the dinosaurs and haven't changed much scientists found out that they grow around a half an inch per year so with a little bit of quick math they can easily find out the age of these tough sharks imagine seeing a shark that's older than the usa .
This next creature is probably the most durable indestructible and cutest on the list it's called a tardigrade but scientists nickname it water bear because i guess it looks like one but it's not exactly bear size it has eight legs and hands with a strange little nose and these bizarre microscopic creatures are indestructible .
They're known to live in the most extreme places on the planet they're fine with temperatures as high as 300 and as low as minus 330. volcanoes frozen desert nights they can even handle radiation and massive amounts of pressure in the deepest parts of the ocean they can even survive the vacuum in .
Space no tiny little spacesuit or anything that would be cute enough so far they've survived 10 days on the outside of a spaceship but they could probably do longer tardigrades might be able to outlive humans if there's some sort of worldwide catastrophe microscopic organisms in .
Charge of the planet wonder what that would look like whether it's all the volcanoes erupting at once or another ice age or even another pesky asteroid tardigrades probably wouldn't even notice scientists are studying them to see if they can help us with some next level biotech it looks like a prehistoric creature .
That came from the time of dinosaurs this scary beast is called the basking shark it can grow up to 39 feet people have only reported three of them in the past 160 years the last sighting was in 2015 and before that about 80 years ago these sharks sometimes rise to the surface to filter out small animals such as shrimps and other small crustaceans .
When they want to have a nice tasty seafood dinner but when there isn't enough grub at the surface they go down to the depths of almost 3 300 feet where they tend to stay for months which is something researchers discovered using satellite tags tag you're it now basking sharks like to spend their time in more temperate waters but they .
Can migrate long distances they live across the globe but in warm tropical or sub-tropical areas they won't go near the surface because they're not fans of high temperatures the lion's mane jellyfish is not that rare but it's fascinating how large it is it's the biggest among jellyfish species and the longest animal its total length can .
Reach 120 feet that's approximately 23 feet more than the longest blue whale scientists know about the jellyfish has around 70 to 150 tentacles and they all contain huge amounts of neurotoxins that can seriously harm you if you come in contact with the animal but people don't usually come across this type of jellyfish because it rarely lives near .
The coast preferring the open ocean generally you can find the lion's mane jellyfish no deeper than 65 feet below the surface where it dines on small fishes zooplankton and some other types of jellyfish it uses its tentacles to catch its value mail hey you want fries with that the giant phantom jelly comes out of the .
Darkness and depths of the ocean's midnight zone its sun hat shaped bell reaches over three feet across this bell trails four ribbon-like mouth arms that can be up to 33 feet long this quite rare creature uses its mouth arms to catch unfortunate animals swimming around and not knowing what's coming for them .
Giant phantom jelly propels itself through the water with periodic pulses coming from its orange head it glows faintly and mysteriously in the pitch black depths it lives across the globe in all the oceans except for the arctic i'm guessing it's too cold because of its odd shape people often call the ore fish the dragonfish or sea .
Serpent it's about 26 feet long which makes it the longest bony fish we know about and lives at depths of 3 300 feet or fish spend most of their time in the deep dark parts of the open ocean in tropical and subtropical areas they almost never come to the surface unless you know invited it's a ribbon shaped and shiny silver .
Creature with a long red dorsal fin and red or like pelvic fins its body has no scales and is very thin the fish can grow to a length of about 30 feet and weigh 660 pounds or fish have really big eyes that help them see better in their dark scary surroundings the frilled shark is definitely one of .
The gnarliest looking marine animals out there if you saw it somewhere you'd probably think you went back to the age of dinosaurs yep the frilled shark is a prehistoric creature because its roots go back 80 million years this living fossil can grow to be seven feet long it got its name from its frilly gills even though frilled sharks .
Have the shark part in their name they swim similar to an eel in a distinctly serpentine way its mouth is terrifying similar to the maw of the great white shark it has 300 trident-shaped teeth lined in 25 roads hey come a little closer huh researchers discovered this creature in the 19th century but people rarely see .
It and no wonder it usually lives at depths of between 390 and 4 200 feet most of the time the frilled shark feeds on squid swallowing them whole its long jaws allowed the frill shark to gape extra wide and swallow animals half as long as its entire body goblin sharks are very rare researchers have spotted fewer than 50 of them in .
More than 120 years but maybe that's for the best since we're talking about a pretty scary fella with a narrow snout and sharp teeth it's also capable of thrusting its entire jaw outward when it wants to catch something sounds familiar as it's lurking through the dark depths of the ocean a goblin shark sees a small squid that looks .
Quite yummy the dangerous animal inches toward the squid when the poor creature notices the predator it tries to dart away but it's too late the shark has already thrust its jaw the whole three inches out of its mouth this jaw is connected to the flaps of skin the shark can unfold this helps a lot because the goblin shark is a sluggish animal so .
It's pretty hard for it to chase its food after finishing its lunch the goblin shark puts its jaw back in its mouth and swims away as if nothing's happened goblin sharks mostly live at the bottom of the ocean like many other shark species they prefer swimming alone a pot of dolphins is happily playing .
Near the water's surface in the north pacific ocean on a sunny day they're about as happy as can be until the surface of the water begins to ripple it becomes more pronounced like a possible tsunami or an underwater volcano preparing to blast their instincts tell them to hide tail .
It out of there but they don't know which way is the safest path out abruptly a tremendous roaring sound fills the air the water explodes outwards as a giant whale bursts into the air hello mama wait that's no whale it's an ichthyosaur a giant sea dragon type monster from the triassic period it's a massive 55 feet .
Long and weighs 45 tons it doesn't look too dissimilar to a dolphin but this sea monster isn't any cousin the dolphins scatter back beneath the water fortunately for them the ichthyosaur is not interested in having them for lunch it's merely playing as well this particular species is far more used to eating marine mollusks smaller .
Fish and squid but there's nothing in sight so it disappears back below the surface swimming majestically with its huge fins and long eel-like tail it had once roamed the land but like other prehistoric land reptiles including modern-day whales and dolphins it returned to the sea and evolved over millions of years .
Its limbs have been transformed into flippers some species had digits on their flippers or phalanges they could almost pass for human hands well hello there some possessed a dorsal fin their heads were pointed and their jaws contained conical teeth to catch smaller prey they had large eyes probably used for seeing .
In deep waters their tail fin made for a powerful stroke like some other sea creatures they could breathe air and were warm-blooded they were sleek and as beautiful as some of today's ocean creatures unexpectedly an underwater time vortex opens in front of it sucking in everything in its path like an .
Underwater black hole the ichthyosaur disappears inside flailing about unable to control its journey back into the deep past soon it spat out again into its own natural timeline of the triassic period during the early dinosaur age approximately 247 million years ago it swims with others of its kind they .
Lived in herds or hunting groups while varying forms evolved worldwide such as the smaller mixosaurus let's stay with this one because it will eventually find its way into modern human hands in evolutionary terms the ichthyosaurs lasted for a very long time millions of years there are many complex factors involved with how they became extinct .
But in simplistic terms environmental changes brought out declines in smaller food groups and more brutal predatory groups some fish had evolved as well and became too fast for the ichthyosaur so we will leave our poor friend here unable to find enough food and losing out to the tougher competition it's .
Hungry tired and weak it simply drifts away with the currents eventually finding itself resting on the ocean floor millions of years passed during the triassic and jurassic era sea levels gradually ebb away exposing vast regions of the desert the area we're focusing on became nevada in the western part of the .
United states during the cretaceous period a volcanic island chain formed geological upheaval continued bringing the ocean floor up into modern mountains embedded in the rock well you can guess not only ancient invertebrates but more modern creatures such as mammoths and giant sloths what an incredible array of .
Wildlife but we're not here for them today let's find out what happened to our friend jump forward and time again to 1998 the place the augusta mountains of northwestern nevada or more specifically a place called fossil hill protruding out of the rock were a few .
Vertebrae researchers could tell whatever creature it belonged to it was clearly enormous it was so embedded in the rock and complex that the excavation took many years in september of 2011 the excavators found more of the beast the well-preserved skull forelimbs and chest region .
It wasn't until 2015 that the now obviously giant ichthyosaur could be fully extracted the surviving fossils were a skull the size of a fully grown man a shoulder and a flipper-like appendage even then it took a helicopter to move it the team named the new species symbol spondylus yungorum symbol spondylus is a .
Greek word meaning spine let's call this one ichthyosaur spiny from now on because it should have a name by now and let's face it it's a lot easier to pronounce spiny was airlifted to the natural history museum in los angeles and further shipped to the university of bonn in germany the study was undertaken .
By vertebrate paleontologist martin sander and his colleagues while collaborating with the university of maine's it was a unique and truly electrifying find as the marine reptile was the largest animal ever discovered from this time as far as we know stated martin sandler it was even the first giant creature .
Ever to inhabit the earth you can think of spiny as the underwater t-rex of his time he's also quite remarkable as his type lived only three to five million years after a mass extinction event known as the great dying heading to the pacific coast will come across some gray whales their skin is .
Covered with parasites and other organisms that make their snouts look like rough pieces of rock we got to get on their nice side first gray whales can attack a large boat a ship or a vessel if they sense their calves are in danger but generally they're friendly and appear unbothered by rowing kayakers in some cases they'll .
Approach small boats and allow humans to touch them though you're required by law to keep your distance if it wants to get closer it will if it feels threatened it will act aggressively now let me show you a fish with a tool on its head the hammerhead shark their skull helps them with hunting their eyes are placed on the hammer's outer edges .
And gives them a 360 degree vertical view but they've got a blind spot in front of their nose their heads are like metal detectors most of what they want is below the sand surface so they lightly dip their heads in the sand and sweep up whatever is under there .
You'll see them in temperate and tropical waters both near the shorelines and offshore they usually move in groups they're mostly harmless to humans and divers but there have been a few occasions where they got aggressive but before they do they'll give you a bunch of warning signs and divers know how to handle them .
I'll show you something kind of smaller the sea lion these creatures are a bit tricky they're playful aggressive arrogant smart and above all curious sea lions can't breathe underwater but they can dive almost a thousand feet deep and they can hold their breath for a long time they take in air through their nose and once they dip their heads .
In the waters their nostrils slam shut if they spot humans at the beach they'll stay away and wait for them to leave wild sea lions aren't the friendliest to anyone especially if they feel threatened the approachable ones have been trained in captivity beluga whales are next they're white with bulgy heads and they're amongst the .
Most social and loudest you'll ever meet their upwards facing mouths make them look like they're smiling when beluga whales are born they're a dark gray shade it takes eight years for their skin to turn white they can change the shape of their heads by blowing air around their sinuses beluga whales love humans once they make .
Human friends they don't want to leave even though they're wild animals they become too entrusting with people marine biologists suggest staying away for their safety have you heard of sea cows those are actually called manatees you'll see some in rivers and others in the ocean even though they're large they usually stay .
In shallow coastal areas munching on sea grass leaves and algae manatees bring their heads to the surface every four minutes or so to breathe but they can hold their breath longer than that they're slow travelers and even if they aren't as smart as dolphins they can understand colors these fellas are gentle giants and they like to approach .
Humans searching for warmth next we've got the basking shark the second largest shark in the world their mouth is their most impressive feature like me since they can open more than three feet wide okay you win these creatures have an intimidating appearance but despite their size they're harmless to humans .
And divers swim with them they're very social and can form schools of 100 individuals they swim near the water surface filter feeding on plankton they too have a bunch of teeth that they don't use do you know which creature can sing loud songs for 30 minutes i know barry manatee .
That might be before your time actually it's the humpback whale scientists aren't sure why they make those low howls and noises they might be trying to communicate with others to attract mates you'll see them near coastlines feeding on tiny food and they use their flukes to propel through the water .
Humpback whales are less friendly than gray whales because they're very cautious but they're the heroes of the ocean they try to save other animals from orcas and experts say they're capable of decision making and problem solving on one occasion a humpback whale jumped in to save a whale biologist from a tiger .
Shark now let's try to spot the expert in disguise the caribbean reef octopus the specialized color cells help it blend in with the sand and ocean rocks rough texture but caribbean reef octopuses are loners and they like to get around on their own this creature is also teeny tiny it can .
Grow almost five inches and with their legs getting as long as the average person's foot if you get too close to them they'll likely turn blue and warn you that they feel threatened even though they're trusting it's better to keep your distance to keep them calm a weird-looking creature walks around .
Like a living vacuum cleaner down in the ocean's pitch-black depths i'm talking about sea pigs they got their name from their pinkish bodies and they fit in the palm of your hand these creatures don't swim they walk around on the sea floor their legs consist of five to seven pairs of enlarged tube feet and they have tentacles around their mouths .
To fiddle through the mud to find scum to munch on yumbo since they're vulnerable they have poisonous skin for protection against other sea creatures if you encounter one it'll be quite friendly but if you want to keep it as a pet you'll need a very deep tank
