Transcript
00:00 A pod of dolphins is happily playing near the water's surface in the North Pacific
00:09 Ocean on a sunny day.
00:11 They're about as happy as can be, until the surface of the water begins to ripple.
00:19 It becomes more pronounced, like a possible tsunami or an underwater volcano preparing
00:24 to blast.
00:25 Their instincts tell them to high-tail it out of there, but they don't know which way
00:29 is the safest path out.
00:31 Abruptly, a tremendous roaring sound fills the air.
00:35 The water explodes outwards as a giant whale bursts into the air.
00:42 Hello, mama!
00:44 Wait, that's no whale.
00:46 It's an ichthyosaur, a giant sea dragon-type monster from the Triassic period.
00:52 It's a massive 55 feet long and weighs 45 tons.
00:56 It doesn't look too dissimilar to a dolphin, but this sea monster isn't any cousin.
01:02 The dolphins scatter back beneath the water.
01:04 Fortunately for them, the ichthyosaur is not interested in having them for lunch.
01:09 It's merely playing as well.
01:11 This particular species is far more used to eating marine mollusks, smaller fish, and
01:16 squid.
01:17 But there's nothing in sight, so it disappears back below the surface, swimming majestically
01:22 with its huge fins and long, eel-like tail.
01:26 It had once roamed the land, but like other prehistoric land reptiles, including modern-day
01:30 whales and dolphins, it returned to the sea and evolved over millions of years.
01:36 Its limbs have been transformed into flippers.
01:39 Some species had digits on their flippers, or phalanges.
01:42 They could almost pass for human hands.
01:45 Well, hello there!
01:46 Some possessed a dorsal fin.
01:48 Their heads were pointed, and their jaws contained conical teeth to catch smaller prey.
01:54 They had large eyes, probably used for seeing in deep waters.
01:58 Their tail fin made for a powerful stroke.
02:01 Like some other sea creatures, they could breathe air and were warm-blooded.
02:06 They were sleek and as beautiful as some of today's ocean creatures.
02:10 Unexpectedly, an underwater time vortex opens in front of it, sucking in everything in its
02:16 path like an underwater black hole.
02:18 The ichthyosaur disappears inside, flailing about, unable to control its journey back
02:24 into the deep past.
02:25 Soon, it spat out again, into its own natural timeline of the Triassic period, during the
02:31 early dinosaur age, approximately 247 million years ago.
02:36 It swims with others of its kind.
02:38 They lived in herds or hunting groups.
02:41 While varying forms evolved worldwide, such as the smaller myxosaurus, let's stay with
02:46 this one because it will eventually find its way into modern human hands.
02:51 In evolutionary terms, the ichthyosaurs lasted for a very long time, millions of years.
02:57 There are many complex factors involved with how they became extinct, but in simplistic
03:02 terms, environmental changes brought out declines in smaller food groups and more brutal predatory
03:08 groups.
03:09 Some fish had evolved as well and became too fast for the ichthyosaur.
03:13 So we will leave our poor friend here, unable to find enough food and losing out to the
03:18 tougher competition.
03:20 It's hungry, tired, and weak.
03:22 It simply drifts away with the currents, eventually finding itself resting on the ocean floor.
03:32 Millions of years passed.
03:34 During the Triassic and Jurassic era, sea levels gradually ebb away, exposing vast regions
03:39 of the desert.
03:41 The area we're focusing on became Nevada in the western part of the United States.
03:46 During the Cretaceous period, a volcanic island chain formed.
03:50 Geological upheaval continued, bringing the ocean floor up into modern mountains.
03:56 Embedded in the rock, well, you can guess, not only ancient invertebrates, but more modern
04:01 creatures such as mammoths and giant sloths.
04:04 What an incredible array of wildlife!
04:08 But we're not here for them today.
04:10 Let's find out what happened to our friend.
04:12 Jump forward in time again to 1998.
04:16 The place, the Augusta Mountains of northwestern Nevada, or more specifically, a place called
04:21 Fossil Hill.
04:23 Protruding out of the rock were a few vertebrates.
04:26 Researchers could tell whatever creature it belonged to.
04:29 It was clearly enormous.
04:31 It was so embedded in the rock and complex that the excavation took many years.
04:36 In September of 2011, the excavators found more of the beast, the well-preserved skull,
04:42 forelimbs, and chest region.
04:44 It wasn't until 2015 that the now obviously giant ichthyosaur could be fully extracted.
04:51 The surviving fossils were a skull the size of a fully grown man, a shoulder, and a flipper-like
04:57 appendage.
04:58 Even then, it took a helicopter to move it.
05:03 The team named the new species Cymbospondylus yungorum.
05:07 Cymbospondylus is a Greek word meaning "spine."
05:10 Let's call this one Ichthyosaur Spiny from now on, because it should have a name by now.
05:15 And let's face it, it's a lot easier to pronounce.
05:19 Spiny was airlifted to the Natural History Museum in Los Angeles and further shipped
05:23 to the University of Bonn in Germany.
05:26 The study was undertaken by vertebrate paleontologist Martin Sander and his colleagues while collaborating
05:31 with the University of Mainz.
05:33 It was a unique and truly electrifying find, as the marine reptile was the largest animal
05:38 ever discovered from this time.
05:40 "As far as we know," stated Martin Sandler, "it was even the first giant creature ever
05:45 to inhabit the Earth."
05:47 You can think of Spiny as the underwater T-Rex of his time.
05:51 He's also quite remarkable, as his type lived only three to five million years after a mass
05:56 extinction event known as the Great Dying.
06:02 It happened roughly 252 million years ago.
06:06 It took out approximately 90% of the world's life forms.
06:09 What caused it?
06:11 The short version is elevated temperatures and increased acidification in the oceans.
06:16 Once one part of the food chain extinguishes, it causes a domino effect, as you can imagine.
06:22 Soon, there's little left to eat, and only the sturdiest can survive.
06:27 The atmosphere also had high levels of carbon dioxide.
06:31 Theorists argue that giant volcanic eruptions caused this in Siberia, known as the Siberian
06:36 Traps.
06:37 It was the largest volcanic eruption in the past 500 million years.
06:42 The eruptions lasted a staggering 2 million years.
06:46 Large volumes of basaltic lava covered a large area of Siberia.
06:50 Even today, the site is covered by about 3 million square miles of basaltic rock.
06:56 Other theories say that an asteroid caused the Great Dying, rather than the volcanoes.
07:01 In any regard, the impact was the same, and 81% of Earth's marine species and 70% of the
07:07 land-based vertebrae species were no more.
07:10 There have been numerous mass extinction events, but Spiny's size and existence are extraordinary
07:18 compared to the Great Dying.
07:20 It usually took 9 million years for species to recover and grow to this size, but he came
07:26 into being in less than half that time.
07:29 Using sophisticated computer models, the researchers examined the likely food web running through
07:33 the area now known as Fossil Hill.
07:36 They recreated the ancient environment through the available data, finding that marine food
07:41 webs must have supported giant creatures like the ichthyosaurs.
07:45 The theory is that our Spiny fed on a diverse and rich diet of marine mollusks, known as
07:51 ammonoids, that flourished from 1 to 3 million years after the Great Dying.
07:55 The now extinct ammonoids filled the ecological void following the mass extinction and had
08:00 excellent living conditions without much prey to interfere with them.
08:05 Ichthyosaurs also evolved rapidly because they were the first more giant creatures to
08:09 populate the world's oceans.
08:11 The mollusks they fed off were also exposed to less competition.
08:16 Spiny had a massive food supply.
08:17 He chowed down like there was no tomorrow.
08:20 Unlike whales that become large due to eating foods like plankton, Spiny and his fellow
08:25 species grew big on the ammonites, and it took them a much shorter time.
08:29 That's a good message for you kids to eat healthily!
08:32 The exciting thing for us today is that these results show that marine ecosystems can build
08:37 up and respond well to such dramatic changes as climate, atmosphere, or water conditions.
08:43 They may have had different pathways, but some ichthyosaurs and whales have similarities.
08:49 They both have large sizes and a lack of prominent teeth.
08:53 Storm whales dive deep to hunt giant squid.
08:56 Spiny hunted similarly.
08:57 They use a type of filter feeding to extract the food from the water.
09:02 Our friend likely ate fish and possibly squid, and ever smaller ichthyosaurs.
09:07 Ouch!
09:08 Other ichthyosaur forms had lots of teeth, with a skull more like a giant lizard.
09:13 They had razor sharp teeth.
09:16 Ichthyosaurs swam the ancient oceans for nearly the whole of the dinosaur age.
09:20 Ichthyosaur fossils have been found in many other countries, such as England, Norway,
09:24 Japan, Germany, Colombia, China, and Australia.
09:28 They were the underwater planet rulers of their day.
09:31 As the sun sets 250 million years ago, we might imagine Spiny having a better outcome
09:36 than he ultimately did and popping his head out of the water to watch the orange hues
09:41 of the pristine sky.
09:43 He pauses for a moment before, once again, dipping underwater to join his friends, swimming
09:48 happily away with the herd, looking for food and adventure in the deep blues of the Triassic
09:53 Ocean.
10:00 Wanna high five a sea creature?
10:02 Well, put your flipper, I mean hand up, for the Tasmanian red handfish.
10:07 This fish doesn't swim like a fish.
10:09 It walks.
10:10 It uses its flipper-like hands to stroll around on the ocean floor.
10:15 These bottom walkers are disturbed by swimmers and boats a lot.
10:19 Some people even want to take them home as pets.
10:22 I think it's better to just give them a wave and swim on by.
10:26 The vampire squid.
10:28 Its species name is Vampyroteuthis infernalis, which translates to "vampire squid from
10:35 hell."
10:36 Oh yes, this vampire squid means to terrify everyone with its name.
10:40 Its dark red color, its spikes at the bottom, and the scary fact that it can basically turn
10:45 itself inside out.
10:48 The vampire squid loves putting on a good show, but it's as harmless as a kitten is
10:52 to humans.
10:54 It's as if Dracula scared the pants off you, but he didn't have blood-sucking fangs.
10:59 The vampire squid feeds on food particles from plants and animal matter floating near
11:04 the ocean's surface.
11:05 Since they're not predators, they need good defensive strategies, and their vampiric look
11:10 is designed to ward off large creatures who want to eat them.
11:14 Turning themselves inside out is a defensive mechanism since the spiky areas in the inner
11:18 skin are more intimidating.
11:20 They also shoot out a substance that does not have color, but is packed with bioluminescent
11:26 particles to distract predators.
11:29 The vaquita.
11:31 Going out on a boat off the coast of Mexico sounds like the perfect vacation.
11:35 The sun, the blue water, the most endangered sea creature… wait, what?
11:41 The vaquita isn't dangerous, but don't expect it to stick around to say hello or
11:45 sign any autographs.
11:46 It's incredibly shy.
11:49 This little cow, that's what it means in Spanish, is one tiny sea mammal.
11:53 With those black markings around its eyes, it looks more like a sea panda to me.
11:58 Seeing one should make you feel very special.
12:00 They're on the brink of extinction, mostly because they get caught by accident in fishing
12:04 nets.
12:05 It's estimated that there's only 10 left in the wild.
12:10 The blue dragon.
12:12 This little creature looks like something out of a kid's fantasy movie.
12:15 It's called the blue glaucus, casually referred to as the blue dragon or blue angel.
12:21 It can be found in many places, the Atlantic, Pacific, and Indian Oceans.
12:25 It's kind of a mollusk and it only grows to be about an inch long.
12:30 What you think is the back is actually the mollusk's bright underbelly.
12:34 It regularly floats on its back so that its blue colors help it camouflage with the water's
12:38 waves.
12:39 The blue dragon isn't just pretty, it's also smart.
12:43 It usually feasts on Portuguese man o' wars, also known as Fisalia fisalis.
12:49 The blue dragon stores their stinging cells for later use, in essence, stealing their
12:53 defensive mechanisms.
12:55 When the blue dragon is threatened, it releases those stinging cells it's stored, directing
13:00 them at an enemy to sting them with more power than the Portuguese man o' war would have
13:04 been capable of.
13:06 As they can store a huge amount of stinging cells, they can be a threat to humans.
13:10 So if you find one, don't pick it up.
13:12 It's best to admire it from a distance.
13:15 The barrel-eye fish.
13:17 If you ever wanted to have Superman's x-ray vision, looking at the barrel-eye fish will
13:21 make you feel like you gained that superpower at some point in your life without even realizing
13:26 it.
13:27 The barrel-eye has a transparent head, so you can see how their eyes and brain look
13:31 inside.
13:32 This magnificent creature lives in the deep sea.
13:36 This is the lowest level of the ocean, where strange creatures roam in near-freezing temperatures
13:41 and constant darkness.
13:43 They're exposed to water's pressure that's almost 1,000 times that of the surface.
13:48 If the idea of the deep sea sends a shiver down your spine, stay tuned to learn about
13:53 another of its creatures later on.
13:56 The barrel-eye fish can be found in the Atlantic, Pacific, and Indian Oceans.
14:00 You might be wondering, "Why, oh why, would a fish have a see-through head?"
14:05 And that would be a fair question.
14:07 Since the species was discovered in 1939, it was believed that the fish's eyes were
14:11 set to see straight ahead and couldn't move.
14:14 So it was assumed that they had tunnel vision.
14:17 Scientists Bruce Robinson and Kim Riesenbichler from the Monterey Bay Aquarium Research Institute
14:22 recently discovered that the fish can move its eyes vertically to see through the top
14:26 of its translucent head, thus noticing if there are predators or prey nearby.
14:32 The transparent head also allows more light to enter so they can detect prey better.
14:37 It's believed that the barrel-eye fish eats jellyfish and small fish species.
14:43 If you dive in the ocean at night, you might be lucky enough to see how orange ball coralimorph
14:48 blooms in the dark.
14:50 But make sure to be quick because as soon as you turn on your flashlight to take a good
14:54 look, it will retract its tubes back into itself.
14:58 The Megalodon The whale shark isn't the biggest shark known
15:02 to humans.
15:03 If the entire shark species were a kingdom, the prehistoric Megalodon would be the ruler
15:07 of the sea.
15:08 Megalodon roamed the ocean a long time ago, oh, about 15.9 to 2.6 million years back between
15:15 the early Miocene and late Pliocene eras.
15:18 While they've long been extinct, people are still amazed to learn about these gigantic
15:22 sea beasts.
15:24 Megalodon could reach anywhere between 45 feet to 60 feet in length with jaws more than
15:29 6 feet wide.
15:31 A fossil of a tooth that once belonged to a Megalodon measured at 7 inches.
15:36 Needless to say, I'm pretty stoked that these guys have long been extinct.
15:40 But there's still some adventurers out there hoping to meet this monster one day.
15:45 The Dumbo Octopus This adorable creature or creepy creature,
15:50 or however you want to see it, is officially called Grampotiuthis.
15:54 More casually, it's referred to as the Dumbo octopus named after the Disney character.
15:59 Though Dumbo, the elephant, not the octopus, was teased for his big ears, it's highly
16:04 unlikely that this adorable octopus gets teased by its water neighbors.
16:09 They are the deepest living octopuses, living in the deep sea.
16:13 And you know how scary that place is.
16:15 They're only about 8 inches tall, and spend their days hovering just above the sea floor
16:20 eating snails, worms, and other food they find in the current or near ocean vents.
16:25 There are nearly 17 species of Dumbo octopus, and they all have differences in height, color,
16:31 and body parts.
16:32 If you can't get enough strange animals, you'll be glad to learn that the deep sea
16:36 has barely been explored by humans.
16:38 So keep an eye out.
16:40 There are bound to be more fascinating animals discovered in the deep in the future!
16:45 The sea angel.
16:47 These creatures might look and sound pretty cute, but their diet is far from sunshine
16:51 and lollipops.
16:53 Their favorite food are sea butterflies.
16:55 They lay mucus traps for them and wait in ambush.
16:59 The squat anemone shrimp.
17:01 This shrimp is tiny, only 0.5 inches.
17:05 It's also known as a dancer shrimp because of its peculiar behavior.
17:09 When agitated, it raises its bottom above its head and does a little dance.
17:14 Divers also say it readily jumps on their hands and cleans them.
17:19 The coconut crab.
17:21 This guy may look pretty creepy, especially when the sun goes down.
17:24 Mature coconut crabs are around 3 feet in length.
17:28 Their preferred foods are coconuts, but they can also hunt down lizards and even large
17:33 birds.
17:35 The slender snipe eel.
17:37 Slender snipe eel is a slim and long creature that's still a mystery for marine scientists.
17:43 It's 4 feet long and it has at least 750 bones in its spine, which is much more than any
17:49 other animal in the world.
17:51 The sea pen.
17:52 Sea pen is 7 feet long and it has a lot of varieties, but most of them look indeed like
17:58 a pen or a quill.
18:00 The similarity is even more striking when the animal has a water-filled bulb that anchors
18:04 it to the floor.
18:06 The Persian carpet flatworm.
18:09 This creature looks indeed like a carpet, despite being very small by comparison.
18:14 It's only 4 inches long, able to become both male and female.
18:18 It doesn't really mate with other flatworms.
18:20 Rather, it fights them for the right to bear posterity.
18:24 The flamingo-tongued sea snails.
18:26 Tourists love these extraordinary snails for their pretty colors.
18:30 Thinking it's a shell, but in fact, the shell is quite dull and hidden underneath colorful
18:34 soft tissues.
18:36 They eat softer toxic parts of corals and store their toxins to protect themselves.
18:41 (upbeat music)
