00:00Did you know that animals see the world differently from us?
00:03Take this. Pigeons actually have better vision than humans.
00:06Crazy, right?
00:07So let's try to see the world from the animal's eyes.
00:11Let's start with snakes.
00:12Their way of seeing the world is totally different from ours.
00:15They have special infrared-sensitive receptors in their snouts.
00:18This allows them to see the radiated heat of warm-blooded mammals.
00:23Now let's move on to cows.
00:24These big guys don't see colors as well as humans do.
00:27They can't see the color red, because they don't have the necessary receptors in their retinas for that.
00:33So they only perceive variations of blue and green.
00:36Also, they don't like it when someone approaches them from behind.
00:40They have a near-panoramic vision.
00:42And the only area they can't see is directly to the back.
00:46So if you're ever sneaking up on a cow, make sure you give them a heads up.
00:51Horses have a blind spot right in front of their faces because of their eye placement.
00:55This means they can't see things directly in front of them.
00:57Also, they don't see as many colors as we do.
01:01Just like cows, their world is mostly made up of greens, yellows, and blues.
01:05Poor guys.
01:07Fish eyes have ultraviolet receptors and a more spherical lens than humans.
01:11This gives them an almost 360-degree vision.
01:14As for colors, they're able to see all the same ones as we humans do.
01:18But because light behaves differently underwater, they have a hard time discerning red and its shades.
01:24Deep-sea fish can easily see in the dark, which is pretty cool.
01:28Sharks, on the other hand, can't distinguish colors at all, but they see much clearer under the water than we
01:34do.
01:36Birds have some pretty unique ways of seeing the world.
01:39Unlike humans, birds can see ultraviolet light.
01:42This helps them differentiate between males and females of their own species, as well as better navigate in their surroundings.
01:50Also, they are very good at focusing.
01:52For example, falcons and eagles can focus on a small mouse in the field up to a distance of one
01:57mile.
01:57A pigeon can see all the tiny details.
02:00So if you ever need to find a crack in the pavement, just ask a pigeon.
02:04And by the way, it has a 340-degree field of vision, and generally their vision is considered twice as
02:09good as a human's.
02:11There, you have it.
02:11I'm envious of a pigeon.
02:15Insects have some weird vision patterns, too.
02:18Flies, for example, have thousands of little eye receptors that work together to give them a big picture of what's
02:24going on around them.
02:25And get this, they see everything in slow-mo.
02:28Plus, they can see ultraviolet light.
02:31It helps them with communication.
02:34Bees have their own problems.
02:36These guys can't tell what the color red is.
02:38To them, it looks like a dark blue.
02:40How messed up is that?
02:42Now, rats.
02:43These little guys can't see red either, but that's not the weirdest part.
02:47Either of their eyes moves on its own, so they're seeing double like all the time.
02:51It's a wonder they don't run into more walls, am I right?
02:55Cats don't see shades of red or green.
02:58But they do see brown, yellow, and blue hues like a boss.
03:02Plus, they got a wide-angle view, so they can peep more stuff on the sides than we can.
03:07There's more, though.
03:08When it's pitch black outside, cats become ninja-like.
03:11And can see six times better than us.
03:13Their pupils adjust to any lighting-like magic.
03:45Now, let's talk about dogs.
04:11There are sharks that glow in the dark.
04:13For example, swell sharks.
04:15They live in the dark ocean depths, almost 1,700 feet under the surface.
04:21No one knows why exactly, but they emit a fluorescent glow only other swell sharks can see.
04:27Scientists detected the glow because they used filters that blocked out yellow light.
04:32They think that could be the way for these big fish to communicate with their buddies.
04:37This glow helps sharks fight infections on a microbial level.
04:42Cowbirds have secret passwords they use to recognize each other.
04:46They're a specific type of parasite bird since they lay their eggs in other bird species' nests.
04:52The young cowbirds have an inner mechanism where they recognize their species singing, like some sort of secret password only
04:58they know.
04:59That's how they manage to find others of their kind.
05:03A grizzly bear has an incredibly strong bite.
05:06It may look cute, but if you're close to this big guy, you better stay out of reach of its
05:11sharp claws and especially its mouth.
05:13It's bite force is more than 8 million pascals, which means it can crush a bowling ball.
05:21Some animals have skin-deep stripes, and others have more superficial ones.
05:26Tigers are in the first group.
05:28Not only is their fur striped, but their skin is as well.
05:32It's the same with some other furry big cats, like snow leopards.
05:36Giraffes and zebras are in the second group, since they have patterns only on their coats.
05:42Speaking of zebras, do you think they're black with white stripes or white with black stripes?
05:47At first, it really looks like the second option is correct.
05:51Their black stripes mostly end towards the inside of their legs and on their bellies, and the rest of it
05:57is white.
05:57But that's not true.
05:59Surprisingly, they're black with white stripes.
06:02All of their fur, both white and black, grows from follicles that have something called melanocyte cells.
06:08All animals have these cells.
06:11They produce a pigment called melanin, and it gives color to their hair and skin.
06:17When it comes to zebras, chemical messengers tell which melanocytes send pigment to which area of fur.
06:23That's why zebras have a black and white pattern.
06:26But white is not actually its own pigment.
06:29It's an absence of melanin.
06:31So, black is their default color.
06:35Koalas have fingerprints that are so close to ours that they could even taint crime scenes.
06:40It doesn't seem like they have a lot in common with humans, but take a closer look at their hands.
06:45They have distinctive loops and arches.
06:48So, if any koalas want to do something illegal, it would be a good idea for them to wear gloves.
06:55Ghost crabs growl when they're around creatures they don't like or find threatening.
06:59They do it using teeth in their stomachs.
07:03First, they'll let you know they'll defend themselves if you try anything by showing you their claws.
07:08If that doesn't work, they'll go for fearsome growling noises like dogs.
07:13But the noise is coming from rubbing their three elongated hard teeth inside their stomach.
07:19Ghost crabs produce the same noise when they're grinding up food.
07:24Speaking of teeth, did you know narwhal tusks are actually some sort of an inside-out tooth?
07:30Unlike the majority of other whales, narwhals are the ones that come with a large tusk.
07:35Or tooth that grows from the inside of their jaw.
07:38It has up to 10 million nerve endings.
07:41And they're unprotected, which means its tusk is very sensitive to any type of contact.
07:46It's almost like a piece of skin, because tusks usually don't have many nerve endings.
07:52Up to 95% of humans are right-handed.
07:55And it's the same with bottlenose dolphins.
07:58There are even more right-handed ones among them than among humans.
08:03During one study, scientists found that bottlenose dolphins turn to their left side over 99% of the time,
08:10which means they're right-handed.
08:12They place their right side and right eye closer to the ocean floor as they go for prey,
08:17such as squids, shrimps, or smaller fish.
08:21More cool facts from the ocean.
08:23Did you know humpback whales use bubbles when they go after their prey?
08:27You might think they don't need any special method, considering how large they are.
08:31But when they're lurking for prey in the open waters,
08:34these whales team up and use something called a bubble net technique.
08:39While swimming in an upward spiral, they blow bubbles underwater.
08:43These bubbles make it difficult for fish to escape.
08:47The oldest evidence we have of domesticated cats dates up to 12,000 years ago.
08:53Researchers discovered this almost 20 years ago when they were digging through an ancient village in Cyprus.
09:00They found cat bones right next to human ones,
09:03which suggested they were close even when their lives came to an end.
09:07Humans were hunters, so they domesticated dogs first, somewhere up to 29,000 years ago.
09:13Dogs helped them catch other animals,
09:15but they didn't think they needed cats until they started to settle down and store surplus crops.
09:21Mice became frequent guests in grain stores, so cats came in handy in those times.
09:27Puffins are quite innovative when they want to scratch their bodies.
09:31They can surely be proud of their stunning beaks, but they obviously think it's not enough for scratching.
09:37Researchers noticed they tend to spontaneously take a small wooden stick to scratch an itchy spot.
09:44There's a special type of ant that only lives in a small part of Manhattan.
09:48The Broadway Medians at the 63rd and 76th Street is the area these crawling critters decided was the best spot
09:56for them.
09:57The Manhattan ant looks like it's from Europe, but no European species can actually match it.
10:03Hey potterheads, can you believe there's a thing like chocolate frog?
10:07Well, not quite, but it looks like it.
10:10New Guinea and Australia weren't always separated.
10:13They spent millions of years together until about 12,000 years ago, rising sea levels divided them.
10:19Since they were together for so long, some animals and plants still inhabit both areas, including green tree frogs.
10:27These frogs have spread really far and wide, and some of them, who live in hot, swampy regions surrounded by
10:34plenty of crocodiles,
10:35actually look like they're made of chocolate.
10:38We all know flamingos for their specific color, but they're not actually pink.
10:43They're born gray, and that's how they would stay if it weren't for their diet of blue-green algae and
10:48shrimp.
10:49These foods have a specific natural dye, which is why flamingo feathers turn pink over time.
10:57These little Tasmanian devils grow up and leave their moms.
11:00They socialize together, forming bonds that last for the rest of their lives.
11:04Not only them, counts also have stronger social ties than we think.
11:09They like to socialize, and they make long-lasting friendships.
11:12One research even discovered their heart rates significantly increase as a sign of stress when they're separated from their BFFs.
11:21Imagine you could simply freeze yourself solid during the cold winter days instead of listening to your teeth chatter and
11:27trying to tighten your jacket.
11:29That's what frogs can do.
11:31Aquatic frogs mostly hibernate underwater and spend most of the winter at the bottom of a pond, lake, or some
11:37other body of water.
11:40Toads and frogs are generally cold-blooded, which means the temperature of their body takes on the temperature of their
11:46surroundings.
11:47So, frogs can freeze during the winter because of a high concentration of sugar or glucose in their vital organs.
11:54Once they unfreeze, they continue as if nothing happened.
11:58Octopuses have three hearts and blue blood.
12:02They can move at speeds of 25 miles per hour, and they spray ink that not only blurs the predator's
12:08visual field, but actually harms them.
12:10Also, they have nine brains, the central one and eight smaller brains, located in their arms.
12:16That's why their arms can open a shellfish while the central brain is busy doing something else.
12:22An octopus even tastes with its arms.
12:25They have cells in their suckers that enable the arms to touch and taste in a way that they detect
12:30chemicals marine creatures produce.
12:33That way, an octopus can distinguish prey from rocks.
12:39Squirrels' teeth never stop growing, but the animals wear them down by gnawing on nuts and other hard foods.
12:45The front of the rodent's teeth is actually orange.
12:48It's because they're covered in special, tough enamel.
12:51Bet you're glad you don't have that to deal with.
12:54Some bird species don't mind munching on chili peppers.
12:58That's because they can't feel the heat.
13:01Peppers burn your mouth because they contain a special chemical, capsaicin.
13:05But birds don't have the taste buds needed to feel its effects.
13:09The rhino's horn is made of hair, or at least the same protein that makes up your hair and nails.
13:16This protein is called keratin.
13:18Such a horn is kind of unique, since other animals have horns with a bony center.
13:24The woodpecker can peck the wood 20 times per second.
13:28This pace is almost too high for the human eye to notice.
13:31How much wood would a woodpecker peck if a woodpecker could peck wood?
13:35The number of pecks often reaches a total of 8,000 to 12,000 a day.
13:41A starfish does have eyes, one on the end of each of its arms.
13:45These eyes are light-sensitive groups of cells.
13:49Frogs don't need to drink water.
13:51Instead, they have an area known as the drinking patch.
13:54It's on their bellies and thighs.
13:56They use it to absorb water directly through the skin.
13:59Well, that could save some time.
14:02Most caterpillar species have around 4,000 muscles in their body,
14:06and almost 250 of them are in the head alone.
14:10Christmas tree worms are much more beautiful than you can imagine.
14:14But even though the pines look awesome,
14:16two-thirds of the worm's body is hidden in a calcium carbonite tube.
14:21And the point of this is…
14:22I don't have one.
14:26Narwhal's famous tusks are actually their teeth that are kind of turned inside out.
14:31These unicorns of the sea have just two teeth.
14:34And in males, one of them grows right through their upper lip.
14:38Unlike your teeth, this one is tough inside and sensitive and soft on the outside.
14:44The ante-eater doesn't have teeth.
14:47But it's not a problem.
14:48This creature has a super-long tongue.
14:51This tongue helps the animal lap up more than 35,000 termites and ants every day.
14:57Well, that's one way to lick hunger.
15:00The flea can jump more than 200 times their body length.
15:04If humans had such an ability, they would jump as high as the Empire State Building.
15:09Woo-hoo!
15:10The red-eyed tree frog's eggs can hatch earlier if they sense their environment isn't safe.
15:16Small animals with fast metabolism see in slow-mo.
15:21This helps them escape larger creatures.
15:24Koalas' fingerprints are very, very similar to the human ones.
15:28Sometimes, these animals' fingerprints even get confused at crime scenes.
15:33Probably in Australia.
15:34The hippo's sweat is pink and not exactly sweat.
15:39It's a reddish-oily fluid.
15:41Its function is to not cool the body, but to moisturize the skin and protect it.
15:47This fluid also functions as an antibiotic.
15:50So, you get sunburn or cut, you can smear a hippo all over you.
15:55Polar bear's skin is black, and the hairs of their coat are hollow and almost see-through.
16:00These animals have fur growing even on the bottom of their paws.
16:04This gives them a better grip on ice and protects against cold.
16:09Some species of tarantulas, some of the largest spiders in the world,
16:13can live without food for more than two years.
16:16I still think they're creepy.
16:19Platypuses close their eyes while kissing.
16:21I mean, swimming.
16:23They have special folds of skin covering their ears and eyes.
16:26They prevent water from getting inside.
16:28These animals' nostrils also have a watertight seal.
16:33Emus can't walk backwards, but scientists aren't sure why.
16:37These flightless birds are the only ones that have calf muscles.
16:41Emus can sprint really fast.
16:43They can also travel long distances.
16:46But they can't back up.
16:48Crocodiles can't move their tongue because it's attached to the mouth roof.
16:52It keeps the throat closed and protects the animal's airway.
16:55Water snakes, dolphins, whales, alligators, crocodiles, and turtles can drown.
17:02It'll happen if they stay underwater for too long.
17:05These animals can't breathe in the water.
17:07They can just hold their breath for a very long time.
17:12Only one species of birds can fly backwards.
17:15That's hummingbirds.
17:16Hey, go talk to the emu.
17:17These tiny birds can also beat their wings up to 80 times per second.
17:23Despite what elephant shrews look like, these small animals are more closely related to elephants than shrews.
17:30Maybe that's why they have their trademark trunk-like noses.
17:34Elephant shrews use them to munch on insects.
17:37True enough.
17:38Cats, as well as other felines, can't taste sweet things.
17:43They don't have the taste buds needed for that.
17:45Too bad, more for me.
17:47Flamingos can only eat with their heads upside down.
17:51That's why their lower bill is massive and their upper bill isn't fixed.
17:55Such an arrangement is perfect for upside-down feeding.
17:59But it's the opposite of what other birds have.
18:02It's not easy being pink.
18:05Tiger skin is as striped as their fur.
18:08That's all I have to say about that.
18:10When toucans sleep, they curl into pretty tight balls.
18:14These birds can turn their head so that their tail covers their head and the beak rests on the back.
18:20So yeah, they have a ball.
18:22The ostrich has some of the largest eyes in the animal kingdom.
18:26They're more massive than a bird's brain.
18:29Each eye is as big as a billiard ball.
18:32All clownfish get born male.
18:35But in some circumstances, they can turn into females.
18:39This change is irreversible.
18:42Unlike most fish, when seahorses mate, they do it for life.
18:46Even cuter, when the mates travel, they move side by side and often hold on to each other's tails.
18:52The male usually gets stuck schlepping the luggage.
18:56Termites never sleep.
18:57They don't need to recharge their batteries.
18:59But they can eat 24 hours a day, 7 days a week, on your house.
19:05The sloth needs up to 2 weeks to digest its food.
19:09Hey, take your time.
19:10No hurry.
19:11Nothing on the schedule.
19:14Dogs' nose prints can be used for their identification.
19:17They are similar to human fingerprints and unique for each animal.
19:22Owls don't have eyeballs.
19:24Instead, they have eye tubes that don't move in the eye sockets.
19:29Penguins don't have external ears.
19:31But their hearing is especially sharp.
19:34Especially when they're on the lookout for polar bears.
19:37Shh, let's not tell them.
19:39Jellyfish are up to 98% water.
19:42That's why when they get washed ashore, their bodies can evaporate into the air after just a few hours.
19:49If a traffic jam happens underwater, an alligator will always give way to a manatee.
19:56Nice manners.
19:58Grizzly bears have such a strong bite that they can crush a bowling ball.
20:03So, it's smart just to let them win.
20:07Giant pandas aren't picky about their sleeping spots.
20:10They usually fall asleep wherever they are.
20:13In most cases, right on the forest floor.
20:16The giant panda's newborn cubs are tiny.
20:19They weigh like a small cup of coffee and are smaller than a mouse.
20:24The red handfish can walk along the ocean floor with the help of its hands.
20:30But, of course, they are not hands, but evolved fins.
20:34Really.
20:35Cats don't usually meow at each other.
20:38A study has shown the felines use this way of communication mostly to get attention from us humans.
20:45And it works.
20:47Sloths can't shiver.
20:49It's not that they're too busy digesting that two-week-old meal.
20:52Their fur is sometimes covered with algae.
20:56And when they get too hot or too cold, their metabolism shuts down.
21:01During the hard times, immortal jellyfish transform themselves back into their younger state.
21:07Once they reach the stage when they're nothing but a blob of tissue, like me,
21:12these creatures start to grow again.
21:14And this process can apparently repeat again and again.
21:17The closest living relatives of the T-Rex are chickens and ostriches.
21:23Don't turn your back.
21:25The moray eel has another set of jaws that can extend from his throat.
21:31First, the main jaws close around an unlucky sea creature.
21:34Then, the additional set grabs the eel's future meal with backward-pointing, razor-sharp teeth.
21:41And after that, the captured animal gets dragged back into the eel's throat.
21:45I just lost my appetite.
21:48Some species of snails have hairy shells.
21:51Thanks to these hairs, snails can better stick to wet surfaces.
21:56When humpback whales hunt, they often gather in a group and apply a bubble-net tactic to catch their food.
22:03The bubbles don't let the schools of fish get away.
22:07Snow leopards can't roar like other large felines.
22:10It has to do with their less-developed vocal cords.
22:14But these animals can meow, growl, hiss, and even purr.
22:21Not to drift away from their group while napping, sea otters hold hands.
22:27They can also entangle themselves in giant seaweed for the same purpose.
22:31Hey, it kelps!
22:33Lions are often called the king of the prairie.
22:36I thought it was the king of the jungle.
22:38And still, up to 90% of all the hunting in the pride is done by the females.
22:44The males are in charge of protecting the territory and the pride members.
22:49And they make the delicious potato salad known as hakuna matator.
22:54Cats are famous for their uncanny ability to move their ears.
22:58All because kitties have 32 muscles in each outer ear.
23:03Some shark species can glow in the dark.
23:05Unfortunately, only other sharks can see this greenish glimmer.
23:10You have up to 8,000 taste buds.
23:13But your pooch has just a bit over 1,500.
23:17The blue jay can imitate other birds.
23:19Its favorite is a hawk's call.
23:22The blue jay uses it to scare away other birds from its territory.
23:27Slow lorries are insanely cute and just as treacherous.
23:31They're the only known venomous primates.
23:34They have a gland in the crook of their inner arm.
23:36It secretes toxins that can cause unpleasant consequences in people.
23:41The hartebeast has an amazing evasion tactic.
23:45To run away from other animals, they move in a zigzag pattern.
23:50Bottlenose dolphins have names for one another.
23:53Those are specific whistles.
24:01Giraffes have long, and I mean it, black tongues.
24:04Scientists suppose this color might protect the tongue from getting sunburned.
24:08Well, that's all I got.
24:10See ya!
