Scientists found something seriously strange in the deep sea, and it lives in a world that feels basically impossible. This video dives into bizarre creatures surviving nearly 3 miles underwater, where it’s pitch black, freezing cold, and the pressure could crush most things instantly. But somehow life still thrives down there—tube worms, ghostly fish, and organisms that don’t need sunlight at all because they live off chemicals leaking from the seafloor. Some of them grow around hydrothermal vents like they’re sitting next to underwater volcano chimneys, turning toxic fluids into food like nature’s craziest survival hack. The deep ocean isn’t empty… it’s a hidden alien world on Earth, and it’s way weirder than space 🌊 Animation is created by Bright Side.

00:00If you could dive right into the mysterious darkness of the ocean depths, who knows what you'd come upon?
00:08Legends that are hundreds of years old mention some giant sea monsters hiding deep down below the ocean waves,
00:14like the Kraken, the Loch Ness Monster, the Hydra, Leviathan, and so many more.
00:20Okay, no one has ever seen such monsters, but there are still weird and unusually big sea spiders, squid, worms, and many other animals that grew way more than we'd expected.
00:38Take a look at the colossal squid from sub-Antarctic waters.
00:42It's around 14 times longer than the arrow squid that lives near New Zealand.
00:46And deep down in the Pacific Ocean, there's a sea sponge as big as a minivan.
00:53Oceans contain about 96.5% of all water on our planet.
00:58Up to 80% of all life on Earth we've discovered is under the oceanic waves.
01:03We haven't explored, mapped, or even seen more than 80% of the ocean.
01:08In fact, we've mapped Mars better than we have the ocean bottom.
01:12The pressure down there is insane, and it would make you feel like you're holding up almost 50 jumbo jets.
01:20And temperatures at such depths are extremely low.
01:24Conditions deep below the oceanic surface are harsh, so creatures that live there need to adjust.
01:30That's why many of them grew very, very big to survive.
01:34Creatures that live in cold, dark depths are so big because of a phenomenon called deep-sea gigantism.
01:42The deeper you go below the oceanic surface, the less sunlight there is.
01:47That's why the temperatures drastically fall.
01:50The result of this is increased cell size and longer life of creatures.
01:54Also, these creatures don't have as much oxygen as the marine animals that live in shallower parts.
02:02And their food sources are minimal.
02:04Much of the food they get comes from shallower waters, and only a little bit trickles down to the deeper parts.
02:11And when there's not enough food, being large is an advantage.
02:14Larger creatures can move farther and faster to find something to eat.
02:20Their metabolism works slower.
02:23They don't digest the food that fast, so they can store food and conserve energy for hard times when they can't find anything to eat.
02:31They don't need to regulate their body temperature either, which also helps them save some energy,
02:36which they can then transfer to other body processes.
02:38They mature more slowly and later than those living in shallow waters.
02:44The majority of fish species that dwell in deep waters live 30 years or even more.
02:51Orange ruffy fish, on the other hand, live up to 150 years.
02:57This fella grows 24 feet in length and weighs up to 1.5 tons.
03:02But it grows to be so big for centuries.
03:05They start looking for partners when they're 150 years old.
03:09And they can also live this long because there are not so many predators at such depths.
03:14Also, there are no humans or other things that can disturb them or endanger their existence.
03:20At such depths, the environment is pretty stable.
03:24So many animals there are like living fossils because they probably haven't changed in millions of years.
03:30The first 650 feet of the ocean's depth are considered to be the open ocean.
03:37The majority of the marine life we've discovered lives there, since that's the area the sun can still reach.
03:43And then, as you continue going deeper, you reach the twilight zone.
03:48It seems like nothing lives there.
03:50But at about 820 feet, you see a small oasis of ancient life blooming.
03:58For example, there are sea lilies, animals that have been living at such depths unchanged for millions of years.
04:05Coelacanths, another living fossil, have been living in the ocean for more than 360 million years.
04:11Hagfish haven't changed in a very long time either.
04:15For over 300 million years, this creature lives at depths of 5,500 feet.
04:22They evolved before the rest of the vertebrates, which is why this is the only living animal without jaws or a spine, even though it still has a skull.
04:32Deep-sea creatures can't survive in shallow waters.
04:36They've evolved to live in depths under bigger hydrostatic pressure.
04:40Humans and other organisms that have internal spaces filled with gas would end up crushed if we could go to such depths.
04:48That's why deep-sea divers always need to wear special dive suits designed for surroundings with higher pressure,
04:54even though they're not going that deep to the areas where these giants live.
04:58But near Antarctica, you can see gigantism way closer to the surface.
05:11Like giant sponges, sea slugs, sea spiders the size of a dinner plate, worms, and even some enormous single-celled organisms.
05:19They all tend to chill in shallower waters.
05:23Scientists are not sure why exactly, but they think it could have something to do with oxygen.
05:27Giant species use just a little oxygen, and the waters around Antarctica are pretty rich in it,
05:34which means there's hardly any limit to these animals growing bigger and bigger.
05:40Back to deep-sea creatures.
05:42As mentioned, they had to adjust to strong pressure, so they almost don't have any air gaps in their body at all.
05:48They're mostly water-based, and since water is incompressible, which means it's not something you can compress,
05:56it helps them stay unaffected at such high pressure.
05:59But because of all that, if they were to go up towards the surface, they'd probably swell up, maybe even explode.
06:07Just look at the blobfish, the one that takes the title of the ugliest animal in the world.
06:12It looks normal deep down below the surface, where its natural habitat is.
06:17But when it gets up to the surface, where the pressure is 120 times lower, it changes its shape.
06:23The blobfish doesn't have a skeleton or muscles, so without high deep-sea pressure, it ends up being all floppy and saggy.
06:31The dark oceanic depths are not just scary to watch, but to listen to as well.
06:39In 1997, scientists were trying to find underwater volcanoes located off the South American coast.
06:46During their travels, they recorded one of the loudest noises ever registered.
06:51It was pretty weird, too.
06:52It was so loud, even sensors from more than 3,000 miles away managed to pick it up.
06:58They later called it the Bloop.
07:00It took them 15 years to conclude the sound came from an ice quake.
07:06That's when seismic activity breaks frozen ground.
07:10Water at the bottom of the ocean is not always extremely cold.
07:14There are hydrothermal vents on the seafloor, and the water that comes out of them can be up to 750 degrees Fahrenheit.
07:22Powerful pressure, yep, the same one that would crush you, is something that doesn't allow the water to boil.
07:30There are hundreds of animal species that live near deep-sea hydrothermal vents.
07:36Some of them, such as tubeworms, are not like anything we have seen before.
07:41These worms absorb chemicals from vent fluids.
07:44That's how they feed bacteria that live in them.
07:46And in return, those bacteria give them the carbon the tubeworms need to survive.
07:52Two-thirds of all of the coral species scientists discovered live in dark, deep, and extremely cold parts of the ocean.
08:02Some even live in parts that are 3 miles deep.
08:05They can survive at low temperatures, such as 28 degrees Fahrenheit.
08:10Some of these cold-water corals are more than 8,000 years old.
08:13They form amazing structures that can rise up to 115 feet tall.
08:20The deep is not just a mysterious world of unusual creatures.
08:24The landscape under the oceanic surface is magnificent, too.
08:28The canyons hiding there make even the Grand Canyon seem small.
08:32For instance, check out the one located in the Bering Sea, the Jem Chug Canyon.
08:37Its vertical relief is more than 8,500 feet deep.
08:41That's huge!
08:44The largest ocean waves are not the ones you can see from the shoreline.
08:49They occur under the surface, and they're called internal waves.
08:52They take place between two water masses that have different densities.
08:57They travel at speeds of thousands of miles per hour and can be 650 feet tall.
09:02So, if you ever take the Galapagos cruise, you might be lucky enough to see one pretty remarkable fella.
09:12It's called the red-lipped batfish, and it looks like some sort of bat that overdid its makeup.
09:19You can find it at depths from 50 to 300 feet, and you probably won't miss it because it can grow up to 10 inches long.
09:26They mostly chill on the seabed, where they shuffle their way along the seafloor on their stubby little fin legs with pretty large feet.
09:36Yup, very odd to see a fish walking.
09:39But from time to time, they come to the surface to see if there's something interesting up there.
09:44You can also find them at the edge of reefs.
09:48Red-lipped batfish are not fans of warm waters, so you'll mostly find them in colder ones.
09:54It's an anglerfish.
09:56That's the type of fish that lures its potential prey with a fleshy lobe.
10:01Do you see it here on a filament that arises from their snout?
10:05These fish usually come with a big head and wide mouth.
10:09Eh, no comment.
10:10Their tail and bodies are relatively small.
10:13The red-lipped batfish has a fleshy growth on its head.
10:17That's how it catches smaller animals, such as mollusks, shrimp, and little fish of opportunity.
10:24Now, check this bizarre creature lurking in the deep sea.
10:28It's called a tripod fish, and you can find it all across the Indian Pacific and Atlantic Oceans.
10:35Look at their long, bony fins.
10:37They can extend up to 3 feet from their underside and tail.
10:41Scientists think they pump fluid into these fins when they're standing so they can remain rigid.
10:48When they're swimming, their long fins softly float beneath them, which can sometimes look a little bit awkward.
10:54I mean, the walking part looks kind of weird, too, but cool, you must admit.
10:58Tripod fish evolved to sit on their pretty long fins to be taller.
11:04Because that way, it gets into a perfect position to catch fish, tiny prawns, and other small, unfortunate, yet tasty animals the ocean current brings right into their mouth.
11:15It's a perfect mechanism when you think about it.
11:18Currents are barely present at the seabed level, so they'd have to work much harder.
11:23And this fish can't even see the prey coming.
11:26It's almost blind because it spends most of its time in a dark habitat.
11:31But its long fins feel the vibrations in the muddy sediment, little animals that pass nearby may.
11:38And these pectoral fins that sit right behind its head are some sort of antenna.
11:44It gives them extra information about incoming dinner.
11:47Now, you must admit, you haven't seen that many grumpy-looking animals like this cusk eel.
11:54They do have long fins and long bodies, plus their name says it, but they're not actually eels.
12:01The cusk eel family has different members, each with its own specifics.
12:06For example, the faceless cusk.
12:09Just as its name says, the species mostly don't have a face.
12:13Some have eyes that function, while others don't.
12:16Some produce weird sounds while looking for a partner.
12:20And many of them live in deep waters.
12:23Many fish have pelvic fins under their body.
12:26But cusk eels took it to the next level.
12:29Their pelvic fins move forward through their evolution,
12:32which is why you're now looking at long and slender barbells here under their head.
12:37And the real eels don't even have pelvic fins.
12:41You can see flying fish jumping out of warm ocean waters across the globe.
12:45Thanks to the specific shape of their slim body,
12:49they can develop a speed of about 37 miles per hour while they're still underwater.
12:55When they reach that speed, they just angle upward and break the surface.
12:59They rapidly beat their tail while it's still under the surface.
13:03They propel themselves with a little help from their friends,
13:06I mean, from their big pectoral fins that look like wings.
13:10That's how they escape bigger animals that come after them.
13:13And there are so many predators out there lurking from the ocean depths and hoping to catch flying fish.
13:20For example, tuna, mackerel, swordfish, marlin, and some other bigger fish.
13:26The challenge is big, so the flying fish needed to develop a good strategy to escape.
13:32But when they're on the surface, they sometimes become a target to birds.
13:37Also, they're attracted to light.
13:39And fishermen know that, so they use light to catch them.
13:43It seems no one wants to leave them alone.
13:45Now, at first, it looks like you're looking at a small plastic bag.
13:51But it's actually a real, but still pretty bizarre, marine animal that can grow up to 6 inches.
13:58From a different perspective, you see how it got its name,
14:02thanks to its pink-colored body, and probably because it enjoys the muddy seafloor so much.
14:08That's all it has in common with pigs.
14:10These little fellows are actually a kind of sea cucumber.
14:14And, you must admit, they're surprisingly adorable with their tube feet on their back, underbelly, and around their mouth.
14:22These creatures spend most of their time snuffling through the muddy seafloor.
14:27They mostly eat remnants of dead algae or some other tasty bits that have fallen somewhere from the surface.
14:33Of course, they can eat bigger stuff, too.
14:36For example, an entire whale.
14:38Sea pigs are great deep-sea babysitters for juvenile lithotid crabs.
14:44Here, you try to pronounce that.
14:46Researchers saw these little crabs hiding under and climbing on sea pigs.
14:51It was probably a way for the young crabs to stay safe from dangerous predators.
14:56And a way for sea pigs to kill some time and earn some extra cash.
15:00Now, at first, a sea angel looks like some creative animator decided to create a cartoon with such a heartwarming character.
15:10But what you're looking at is a real creature, a small, swimming sea slug.
15:15Its body is transparent, which gives the creature such a fairytale look.
15:20And check out its graceful, flapping wings.
15:24It's definitely not something we'd expect from slugs.
15:27Given a choice, they'd prefer to stay in cold waters.
15:31Snails and slugs usually fall into a category called gastropods.
15:35And the members of this group usually have muscular feet.
15:39But in the case of sea angels, it developed into appendages that remind of wings.
15:45This is what helps them with swimming in open waters.
15:48And they don't have shells either.
15:50But don't let their sweet angelic appearance dupe you.
15:55These creatures are quite sneaky.
15:56They use their tentacles and this piece called radula when they want to pull other swimming snails from their shells.
16:04And do what?
16:05Oh, that?
16:07When I first looked at this creature called giant sephonophore,
16:11I didn't think it was scary because it looked like some sort of centipede.
16:15And how giant can these be?
16:17Well, it seems they can stretch to be 130 feet long.
16:22Okay, it doesn't look scary even at a second look.
16:24But I still wouldn't like to face it.
16:27It's like you're watching some random long rope that's just floating through the ocean depths.
16:32Although it looks like some silly string that does nothing,
16:36this creature is a collection of pretty functional parts,
16:39where each is specialized for something else.
16:43Some of its parts are in charge of catching prey, while others digest food.
16:47Some parts exist for reproduction,
16:49while others direct the action of this entire rope,
16:53whoops, I mean body, by swimming.
16:55This animal is bioluminescent,
16:58which means it creates its own line.
17:00When it bumps against some random object on its way,
17:04its stem glows,
17:05and you can see a bright blue line.
17:09Isn't the flapjack octopus really cute?
17:12With its stumpy webbed arms,
17:14big eyes,
17:15and fins that remind of ears on its mantle,
17:18really adorable.
17:20You'll mostly find the flapjack octopus on the seafloor.
17:23It likes to spend most of its time there,
17:26since that's where it can relax and lay flat,
17:29looking like a pancake.
17:30And when it feels it's time to go somewhere,
17:33this little creature swims or hovers above the seabed.
17:36It flaps its fins and pulses its web of arms,
17:40and looks nothing like an octopus.
17:43More like pulsating jelly.
17:45Well, yes, that's weird.
17:50That's it for today.
