00:00Hello, distinguished guests, and welcome to Aquarium Bright.
00:04Here, you will get to see the most dangerous sea and ocean creatures.
00:07But don't let what I said mislead you.
00:09It's very well possible for you to come across one of these underwater animals during a walk on the beach.
00:16So, take a look at them carefully now, and you might just avoid a disaster.
00:22Is it fish or is it stone?
00:25What you're looking at is commonly known as the stonefish.
00:28But its fancier names include the dornorn and the sinansia.
00:33If you're into diving and observing the underwater, you might already have come across one without noticing.
00:39Its appearance makes it almost impossible to distinguish it from a real stone due to its gray coloration and mottled
00:46appearance.
00:47Especially if you're wearing fogged snorkel goggles.
00:50So, you better pay attention because otherwise, the consequences can be unfortunate since stonefish are the most venomous fish known.
00:58Although some types of stonefishes are known to live in rivers, and most of them are found in coral reefs
01:03near the tropical Pacific and Indian Oceans.
01:07Their needle-like dorsal fin spines stick up when they're disturbed or threatened and inject the poison they contain.
01:14The most common reason why stonefish stings occur is swimmers stepping on them without realizing it.
01:20However, you don't need to be in the water to get stung.
01:23Since they can survive out of the water for up to 24 hours, you'll have to watch where you step
01:28when you're at the beach as well.
01:29Those who got stung by stonefish describe their experience to be extremely distressing.
01:35Their venom can result in infection, and in some cases, it is known to cause shock and paralysis.
01:41It might come as a bit of a shock, but despite its bad reputation, stonefish is edible if it's prepared
01:48properly.
01:49When the fish is heated, its venom breaks down.
01:51And if the dorsal fins, which are the main source of its venom, are removed, raw stonefish is served as
01:57part of sashimi too.
02:00This creature might look like it came out of a science fiction movie, but it's very much real.
02:05Say hello to the blue-ringed octopuses.
02:08Don't be deceived by their small size, which can range between 5 to 8 inches including their arms,
02:14because they're packed with venom to cause great damage to as many as 26 people within minutes.
02:20Just like stonefishes, blue-ringed octopuses are found in the Pacific and Indian Oceans, from Japan to Australia.
02:28They typically live on coral reefs and rocky areas of the seafloor.
02:33Some may also be found in tide pools, seagrass, and algal beds.
02:38Blue-ringed octopuses are not aggressive in nature.
02:41When they're not seeking food such as crabs or shrimps, or searching for a mate,
02:45they often hide in marine debris, shells, or crevices.
02:49It's only if they're provoked, cornered, or handled that they get dangerous to humans.
02:54When they're threatened, they turn bright yellow, or blue iridescent rings appear all over their body
03:00as a warning display towards the potential predators.
03:04Their bites usually come unnoticed, so you might not be able to realize you're bitten until it's too late.
03:10The venom of a blue-ringed octopus can cause dizziness and loss of senses and motor skills, and ultimately, paralysis.
03:17So, better try to keep your hands to yourself and back away in a hurry if you see one.
03:24Nope, it's not a flower bouquet, so don't try to pick and smell one of those pink tube-like things.
03:30What's standing before your eyes is a marine animal called a flower urchin.
03:35It may look gorgeous, but don't let the looks deceive you.
03:38It was named the most dangerous sea urchin in the 2014 Guinness World Records.
03:42Flower urchins inhabit the tropical areas of the Indo-West Pacific, and are found among coral reefs, rocks, sand, and
03:51seagrass sites at depths of 0 to 295 feet.
03:55The most noticeable feature of them is their pedicularia, which are claw-shaped defensive organs that are also found in
04:03sea stars.
04:04What makes flower urchins differ from any other sea urchin is the fact that their pedicularia is, as the name
04:10suggests, flower-like,
04:11and usually pinkish-white to yellowish-white in color, with a central purple dot.
04:17Hidden underneath those flowers, they possess short and blunt spines.
04:21Although many sea urchins deliver their venom through such spines, flower urchins deliver their venom through their pedicularia, or flowers.
04:30If they're undisturbed, the tips of these flowers are usually expanded into round, cup-like shapes.
04:37On their surface, they possess tiny sensors with which they can detect threats,
04:42and once they contact such threats, these flowers immediately snap shut and start injecting venom.
04:48What's weird is that the little claws of the flowers can sometimes break off from their stalks,
04:54stick to the point of contact, and continue injecting venom for hours into whoever touched it.
05:00Yeesh!
05:02Looks like a giant puddle of melted strawberry ice cream, right?
05:06You wish!
05:07It's a lion's mane jellyfish, which is also called giant jellyfish, arctic red jellyfish, or hairy jelly.
05:15They're known to prefer cool water.
05:17That's why they can mostly be found in the Arctic, northern Atlantic, and northern Pacific Oceans.
05:23But it's possible to spot them around the British Isles or in the Scandinavian waters too.
05:29Lion's mane jellyfish are one of the largest known species of jellyfish.
05:33They get their name from their long, flowing, hair-like tentacles, and can reach lengths up to 10 feet.
05:40And although the average bell diameter of a lion's mane jellyfish is around 20 inches,
05:46they can sometimes attain a diameter of over 7 feet.
05:50The largest lion's mane jellyfish recorded was seen in 1865 off the coast of Massachusetts.
05:57It was measured to have tentacles around 125 feet long and a diameter of 7 feet.
06:03To help you picture it, this is longer than a blue whale.
06:08Lion's mane jellyfish hunt by extending their tentacles outward and creating a trap to catch their food.
06:14Since they have around 1,200 stinging tentacles,
06:18the fish would have to be extremely lucky to be able to escape them.
06:22The sting of a lion's mane jellyfish is usually not life-threatening,
06:27but you would still want to avoid swimming into its tentacles because it can be very painful to humans.
06:32And if you see one washed up on the beach, better not touch it because it can still deliver a
06:37sting long after they've been on the shore.
06:39Fun fact, the lion's mane jellyfish appears in the Sherlock Holmes story,
06:44The Adventure of the Lion's Mane, as a suspect.
06:46But don't worry, we won't give you any spoilers.
06:51The last marine animal you're seeing now is a sea snake.
06:54And yes, they are different from eels.
06:57There are 69 identified species of sea snakes.
07:01Most of them can be found in the tropical and subtropical waters of the Indian and Pacific Oceans.
07:07And they have been around for millions of years.
07:10To make things easier, scientists have separated all different species of sea snakes into two categories,
07:17true sea snakes and sea crates.
07:20Whereas true sea snakes spend almost all their time at sea,
07:24sea crates can spend some time on land as well.
07:27If you see a snake on the beach, you can tell whether it's a land or sea snake by looking
07:33at its tail.
07:34If it's paddle-like, then that's a sea snake you got there.
07:37But make sure to keep your distance in both cases.
07:40All sea snakes need to surface regularly to breathe since they have no gills.
07:45That's why you can come across one while swimming.
07:48If that happens, you better swim away as fast as you can
07:51because most sea snakes have more venom than the average cobra or rattlesnake.
07:55However, since they only attack if provoked, bites are quite rare.
08:01One more cool fact about sea snakes.
08:03They are the only reptiles to give birth in the oceans.
08:07The majority of sea snakes keep the eggs within themselves
08:10and give birth to nearly fully formed snakes while swimming.
08:14That's except for the yellow-lipped sea crate, though.
08:16They come onto land to lay eggs of their little ones.
08:19Remember the stonefish from the beginning of our tour?
08:22They're hunted by sea snakes.
08:24Blame the food chain.
08:26Now, if you step on a sea urchin, you're gonna know right away.
08:30Look at those spikes.
08:32Get the point?
08:33Ow!
08:34While they're not aggressive, they've got a great defense going against any creatures that want to eat them.
08:40Venomous spikes and a poisonous bite!
08:43Pick your poison, literally!
08:45They live in all of the oceans of the world, so avoiding them is out of the question.
08:50They mostly hang out in shallow water, hiding in rock pools and reefs, so unmindful people step on them a
08:57lot.
08:57The long, venomous spikes of the urchin look like needles.
09:01Feel like them, too.
09:03They can go in quite deep, plus they release a strong toxin.
09:07The cure?
09:08Remove the spikes quickly and wash with salt water.
09:12One small marine mammal just loves sea urchins.
09:16Any guesses?
09:16It's the sea otter.
09:19Don't let its cuteness get in the way of its toughness.
09:22These mammals rarely leave the water, and that even includes taking naps.
09:27Holding hands with other otters keeps them from floating away from the pack.
09:31Their fur is the densest on the planet, up to a million hairs per square inch.
09:37Hey, we humans only have about 2,000.
09:40They're also good with tools.
09:42They can use rocks to hammer open shells.
09:44Hey, how else would you open a sea urchin?
09:47You, otter, try it sometime.
09:50Stonefish aren't going to win any beauty contests, unless the pageant is for best rock look-alike.
09:57Their tiny, unreflective eyes and rough skin blend in perfectly with their environment.
10:03A large head, an even bigger mouth, and a home full of…
10:07Yeah, it's rocks.
10:08And just because you're on the beach doesn't mean you're safe.
10:12Stonefish can survive for 24 hours out of the water.
10:16Stepping on one, or even handling one, won't be that fun.
10:20Their dorsal fin spines have extremely strong venom.
10:23It shoots out when they get stepped on, and it can lead to paralysis or even heart failure.
10:29You'll need help fast.
10:31No wonder they're one of the most dangerous creatures in the water, or anywhere.
10:35Be careful when scrambling around rocky areas.
10:38They love to play hide-and-seek.
10:41Box jellyfish tentacles grow up to 10 feet long, and each tentacle has 5,000 stinging cells.
10:48Not bad for a creature that's mostly just water.
10:51Their venom is strong enough to paralyze anything they want to eat.
10:55Now, if you happen to get stung, it's going to hurt.
10:58A lot!
10:59But its toxins contain proteins that affect the heart, skin cells, and even our nervous system.
11:05No wonder it's considered one of the most dangerous creatures on the planet.
11:09I wouldn't recommend using sunscreen, soda, coffee, or other older methods.
11:14They don't work.
11:15Your best bet is some good old-fashioned seawater.
11:19Looks like jellyfish are the rulers of the ocean, not sharks.
11:22Hey, look around your local rock pool.
11:25You might see this sweet little octopus.
11:27It's tiny and has blue rings.
11:30Cute!
11:31But don't fall for it now.
11:33This octopus wouldn't make a good pet.
11:36When provoked, the octopus will start flashing neon blue to warn everyone to stay away.
11:42And I highly recommend you do just that.
11:45Their venom is a thousand times more dangerous than cyanide.
11:49There's also no known antidote for it.
11:51The best thing to do?
11:53Take a quick picture and walk away.
11:55Better yet, just walk away.
11:58Now, not even the octopuses are normal down under.
12:01I'll stick with my shrimp on the bar if you may.
12:03Do you see that large log near the ocean floor?
12:06Maybe it's part of an old ship, a treasure, gold, diamonds.
12:10Hey, I'm rich!
12:11As you get closer, you notice something.
12:14It's swimming!
12:15It's not a shark or a dolphin.
12:17It's a saltwater crocodile.
12:20Now, don't panic.
12:21If you bump into one of these reptiles in the sea, it's unlikely it'll think of you as food.
12:27Crocodiles have a special valve in their throat that stops them from drowning underwater.
12:32But that doesn't mean they can't bite.
12:34Usually, they're heading to a nearby island, and the quickest way there is to body surf.
12:39They can't really take the ferry.
12:41Watching one from a distance should be okay.
12:44Just don't swim to shore right away.
12:46They love to ambush their lunch in the shallow water.
12:49If there's one time I'd like to see a great white shark, it's when I'm diving with crocodiles.
12:55They'll gladly take a crocodile-sized nibble, given the right motivation.
13:00Going out on a boat off the coast of Mexico sounds like the perfect vacation.
13:05The sun, the blue water, the most endangered sea creature.
13:09Wait, what?
13:11The vaquita isn't dangerous, but don't expect it to stick around to say hello or sign any autographs.
13:17It's incredibly shy.
13:19This little cow, that's what the Spanish means, is one tiny sea mammal.
13:24With those black markings around its eyes, it looks more like a sea panda to me.
13:29Seeing one should make you feel very special.
13:32They're on the brink of extinction, mostly because they get caught up by accident in fishing nets.
13:37It's estimated that there are only 10 left in the wild.
13:42The Galapagos Islands are legendary.
13:44Giant tortoises, blue-footed bobbies, sally-like-foot crabs, and red-lipped batfish.
13:50But if you've ever swum around there, you might have seen something really unexpected in the water.
13:56Iguanas everywhere!
13:58These large marine reptiles eat the algae that grow on underwater rocks.
14:03They're strictly vegetarians.
14:05Yeah, I'll bet the fish are happy about that.
14:08A long, flat tail designed for swimming helps them move around,
14:12and sharp claws keep them on the rocks for their daily sunbathing sessions.
14:16But watch them closely.
14:18They sneeze a lot.
14:20They haven't got a cold or anything.
14:21They're sneezing out salt.
14:23A special gland keeps the salt out of their nose, and they've got to get rid of it somehow.
14:29Ooh, sounds painful.
14:30What's cool is that they don't mind us in the water with them.
14:34Because the islands have been so isolated, the creatures here aren't afraid of humans.
14:39Now, with picking up shells on the beach, it's something you like doing.
14:43Make sure the shell you collect doesn't already have an owner.
14:47Snails are everywhere in this world, and they're mostly harmless to the touch.
14:52But there's always one, ruining it for everybody.
14:55Trust me, the cone snail is nothing like its land-based brothers.
14:59It's not vegetarian.
15:01There are over 500 species of this venomous sea creature, with a few that can really hurt you.
15:07These little snails are extremely vicious.
15:10They inject their venom through a harpoon-like tooth.
15:13And they don't even floss.
15:14They're capable of paralysis, blindness, lung failure, and even worse.
15:20Best give some respect to your backyard snails.
15:23You don't want them calling this thing in as a backup.
15:27Want to high-five a sea creature?
15:29Well, put your flipper, I mean hand, up for the Tasmanian red handfish.
15:34This fish doesn't swim like a fish.
15:36It walks.
15:37It uses its flipper-like hands to stroll around on the ocean floor.
15:41These bottom walkers are disturbed by swimmers and boats a lot.
15:45Some people even want to take them home as pets.
15:48I think it's better to just give them a wave and swim on by.
15:53If you think starfish love getting their photo taken, does that mean you can communicate with starfish?
15:58If you could, this one would ask you to leave it alone.
16:02It's always grumpy.
16:04Unlike its washed-up relatives on the seashore, the crown-of-thorn starfish is large and dangerous.
16:10These creatures occur naturally on coral, like the Great Barrier Reef.
16:15Their venom's terrifying, even for humans.
16:18This sea creature is covered in poisonous spines that cause intense and immediate pain.
16:24It can last longer than three hours.
16:26So, what happens if you rub one of these things the wrong way?
16:30Nausea and vomiting.
16:32Not exactly ideal for getting that perfect Instagram pic.
16:36Pufferfish may look small and cute, but handle them wrong and it's game over.
16:42They're a huge hit at underwater birthday parties the world over.
16:45They can turn themselves into balloons.
16:48Funnily enough, not all pufferfish are venomous with sharp spikes.
16:52Some are smooth and adorable.
16:55But the nasty ones have a highly toxic substance inside their body.
16:59Which is weird, because you could pay up to 50 bucks for it at a restaurant.
17:04You ever heard of the Japanese delicacy fugu?
17:07It's venomous pufferfish on a plate.
17:10Young chefs spend years training to prepare it.
17:13But one wrong cut, and you can bet that customer won't be coming back.
17:18Ever.
17:19Sharks are the only animal immune to pufferfish toxin.
17:23Great.
17:24Another thing that makes sharks awesome.
17:28Okay, this is how it starts.
17:30You're woken up by a strange sound.
17:33Not the alarm, though.
17:34It's 5 a.m.
17:36After a few seconds, you realize the strange sound is a knock on the window.
17:41But you live on the 12th floor.
17:43Who or what could be knocking?
17:45Window cleaners?
17:46You live in an ordinary apartment building, not a skyscraper with offices.
17:51The knocking is getting stronger.
17:53You muster up the courage and go to the window, reach for the curtain, and abruptly pull it aside.
17:59What you see is fantastic!
18:02There are flying or floating small fish outside your window.
18:07Thousands of them.
18:08A shoal of sardines rising directly to the sky.
18:12A few knock on your window as they pass.
18:15There are so many sardines, you can't see what's going on outside.
18:19But as the last fish flies by, the full picture opens before you.
18:25Large and small fish fly between the houses.
18:29Octopuses cut through the air with their tentacles into a rain cloud.
18:33A huge whale is slowly drifting toward the horizon.
18:37Above the roof of a nearby house, two sharks chase four sea lions.
18:42A neighbor waves to you.
18:44He holds a fishing rod from the window and waits for the fish to bite.
18:48A school, no, a flock of dolphins flies past your window.
18:53They cheerfully whistle as if they're greeting you.
18:56What's going on?
18:58You turn on the TV.
19:00All the channels are playing the same thing.
19:03Sea creatures of the Earth have learned to fly, leaving the ocean and filling the air.
19:08All flights worldwide are canceled.
19:11And fishing vessels are idle in the seas, oceans, lakes, and rivers.
19:15And no one knows what happened.
19:18Well, you get dressed and go outside.
19:21Sea turtles crawl on the ground.
19:23They shiver, flap their fins, and rise into the air.
19:27A flock of shrimp flies past you.
19:30Has the ocean lost its gravity?
19:32What happened to all the water?
19:34You live in a port town close to the sea, so you decide to go to the coast.
19:40You reach the shore and see the water is calm.
19:44Gravity seems to be intact.
19:46But the sea creatures continue to take to the air.
19:49Six months later, people gradually get used to the new natural phenomenon.
19:56Fish occupy most of the sky.
19:58Planes stop flying, and ship travel increased.
20:02The world's ecosystem is completely changing.
20:05The ocean becomes lifeless.
20:07The number of bacteria, microbes, and various nutrients in the water move to the air.
20:13People get sick more often.
20:15And in some areas, it becomes difficult to breathe.
20:18When it rains, millions of shrimp and small fish fall to the ground along with the water.
20:25Many predatory mammals that have been feeding on fish begin to starve.
20:29They go out to the roads and cities to find food.
20:34Scientists research the flying creatures and find that they somehow changed the structure of their lungs.
20:40But how fish got the ability to fly is still unknown.
20:45It seems nature just decided to push people out of their usual environment.
20:50Fishermen build balloons to fish in the sky.
20:54Some athletes throw a lasso at flying whales and ride them like huge horses.
21:00Though the landing can be difficult.
21:03Creatures that previously swam only in the very depths of the ocean settle at high altitudes.
21:10Researchers discover new, previously unknown fish species.
21:14From the ocean depths, a giant octopus rose into the air.
21:18Many call it the kraken.
21:20This monster has found a new home, right on top of Mount Everest.
21:24Now everyone is afraid to climb this mountain.
21:28The most deep-water creatures reach space.
21:31On the ISS, astronauts observe amazing animals flying past.
21:36They look like aliens from other planets, not Earth.
21:41In some areas, sharks descend to the ground for food.
21:45In these places, people are afraid to go out.
21:48Fishing companies buy huge boeings and attach nets to it to catch fish in the air.
21:53But flights are not safe, especially when a whale suddenly appears smack dab in their path.
22:01Authorities impose curfews in many cities.
22:04People climb to the roofs and watch an incredible sight at night.
22:08Flying jellyfish floating in the air.
22:11Thanks to the bioluminescent protein in jellyfish, they glow.
22:15Stars in the sky mix with the neon transparent creatures.
22:19But be careful!
22:21Some of these jellyfish are very venomous.
22:24Some people were so fascinated by the beautiful jellyfishes that they touched them and ended up in the hospital.
22:31Squid, frightened by the new conditions, release ink into the air.
22:36When a lot of squids do this, the ink blots out the light from the sun.
22:41Massive traffic jams appear on the roads because electric eels fly through the streets and shock traffic lights.
22:47While all of humanity is looking up at the sky, almost no one has noticed what is happening down here.
22:55All over the world, people with a strained physical disability show up in hospitals.
23:01Weird holes form under people's ears.
23:04Doctors don't understand what they're dealing with.
23:07But then, one of the patients jumps into a lake and it turns out he can breathe underwater.
23:14All people grow gills.
23:16At first, most people refuse to go underwater.
23:20But their changed lungs force them to do so or spend the rest of their lives in a gas mask.
23:26Some people are happy to go under the water and start a new life.
23:30The human body adapts to the cold temperatures and high pressure.
23:34There is a lot of work ahead to create cities and infrastructure, but things are not so bad.
23:40There is more space in the water than on land.
23:44One year later, humanity begins to fully migrate to the oceans.
23:49But instead of a new life, they find trash, a lot of garbage.
23:55Billions of tons of plastic are floating in the water.
23:58Their new home turns out to be a massive dump that people have created.
24:03Global plastic recycling starts in all waters.
24:07Every day, people take out tons of trash from the ocean.
24:10The water is getting cleaner.
24:13Trash dumps appear on land.
24:15Five years later, water becomes cleaner.
24:19People don't live in garbage anymore.
24:22All the plastic is on land.
24:24As soon as the problem is solved, humanity begins to build underwater cities.
24:30But then all the fish start to fall into the seas and oceans.
24:34Everything returns to the usual way of life.
24:38People lose their gills, and now they're back on land.
24:41See creatures live in clean water once more.
24:46Philosophers and scientists from all over the world believe that in this way, nature has taught people a lesson.
24:53We understand how to live in a world of garbage and how we should care about our planet.
24:59People are making a considerable effort to preserve the planet's ecology.
25:03Waste recycling plants are built.
25:06Every person stops using plastic.
25:08Harmony begins between man and nature again.
