00:00 Come on buddy, scoot!
00:03 And there he goes.
00:04 There is so much we don't know about the animal kingdom, they just don't teach us at school.
00:09 That's what we're here for.
00:10 Today we're going to learn about why pandas sit alone when they're sad.
00:15 Or why this fish covers itself in snot to get a good night's sleep.
00:19 What does it mean when dolphins swim around you and why in the world giraffes choose to
00:23 fight like this?
00:25 Okay, let's get started.
00:28 Pandas like to sit alone and act like human babies by throwing tantrums.
00:35 Pandas are the celebrity animals because of how much hype they get, and usually you'll
00:39 see them slouching down all alone on a side.
00:43 In fact, to a regular human, they might look sad or even depressed, but that's far from
00:47 the truth.
00:49 Pandas are just really antisocial.
00:51 Other than mating, they just really don't like being around other animals, including
00:56 other pandas.
00:57 In fact, they have a sense of smell that alerts them when another panda is nearby so that
01:01 they can avoid them.
01:02 The reason we know so much about pandas is from studying them in zoos.
01:07 Their wild cousins are so rare that it's practically impossible to observe them.
01:11 The next time you see a panda slouching and sitting all alone, don't worry, they're perfectly
01:16 fine, just spending a little alone time.
01:19 Humans might like to spend time with others, but they value alone time just as much.
01:24 We actually have a lot in common.
01:26 Look at this baby panda throwing a fit right as the caretaker took its favorite toy away.
01:31 After throwing a fit and not getting the toy either, it just sat there and huffed.
01:36 Yup, almost like a real human being.
01:39 The weird thing is, there's a reason pandas and humans evolved their upright postures.
01:44 It could mean we're close relatives.
01:46 It might not sound convincing since we don't eat bamboo all day, but just swap that out
01:51 with Cheetos and there you go.
02:00 Goats faint whenever they're scared.
02:02 Okay, so when we get scared, our bodies go into fight or flight mode.
02:06 But for these little goats, there's a third option which is quite cowardly.
02:10 Faint!
02:11 And it's not just one or two goats, there are millions of these cowardly little guys.
02:20 Fainting goats recently became popular, and not bruised people are sadistic enough to
02:25 scare them.
02:26 But because a whole herd of them fainting is kind of funny.
02:29 It's not their fault either.
02:31 This strain of livestock is called myotonic goats.
02:34 They have a genetic condition that causes their muscles to stiffen completely when they're
02:38 startled.
02:39 The goats don't actually faint, their bodies just sort of lock up as their muscles freeze.
02:44 But luckily, this condition doesn't hurt them.
02:47 They can be scared several times, but they won't be in pain.
02:58 Pygmy lizard shoots blood from its eyes as a defense mechanism.
03:02 Evolution has given us really weird mechanisms and behavior, and one of the weirdest things
03:06 is how the pygmy short-horned lizard defends itself.
03:10 These desert lizards live in a dry and rocky terrain, and their skin does enough camouflage
03:15 to keep them safe from any predators.
03:17 But they can't really become invisible to everyone's eyes.
03:21 That's when their unusual defense mechanism comes in.
03:24 Whenever a horned lizard feels threatened, it can literally shoot blood from its sinuses
03:29 and out of its eye sockets.
03:31 If that isn't a trick right out of a horror movie, we don't know what is.
03:35 Not every lizard has the ability to do this, though.
03:38 This species has two constricting muscles around the major veins in the eyes.
03:43 When these muscles contract, they literally cut off the blood flow to the heart.
03:47 Talk about a daredevil!
03:58 It all pools in the head and with a rapid motion.
04:01 Its pressure gets so strong that it can squirt blood several feet away.
04:06 What's even more amazing is that this process can be repeated many times if needed.
04:11 Hopefully, the lizard doesn't become anemic after a few squirts.
04:15 We still don't know how it can recover so rapidly, either.
04:25 Fish secretes a mucus envelope before sleeping.
04:28 What are you willing to do for a good night's sleep?
04:30 Are you willing to weave your own mosquito net every night?
04:33 Didn't think so!
04:35 Look at these parrotfish.
04:36 They're already pretty weird-looking, but their bedtime routine is even weirder.
04:41 In the mornings, they just roam around, scraping algae off of rocks and corals.
04:45 But at night, they hide in crevices and sleep.
04:48 Yes, these are fish that sleep, but before they do, they secrete music from their gills.
04:54 They keep secreting till it creates an envelope around them to provide them with extra protection.
05:00 Sometimes it takes them an hour to do that, but they do it every night.
05:05 It masks the scent of the fish so that other predators don't chomp on it during its slumber.
05:10 But also, it protects it from parasitic isopods.
05:14 This family of isopods are especially nasty because their larvae feed on the blood of
05:18 fish.
05:19 In other words, they're the mosquitoes of the sea.
05:22 And the parrotfish doesn't want bites all over it at night, hence the mucus cocoon.
05:28 It's a really gross solution, but hey, whatever works.
05:37 Tasmanian Devil Makes a Blood-Curdling Scream The actual devil might appear without a sound,
05:44 but the Tasmanian devils make the world's weirdest sounds.
05:53 Their growls sound like a blood-curdling scream that is so realistic you might think it's
05:57 coming from a human.
05:59 These small creatures are the largest carnivorous marsupials with the most powerful bites out
06:04 of any mammal.
06:06 Moreover, they make a whole range of sounds and none of them are pleasant.
06:16 From raspy screams to shrieks, growls, snorts, and grunting.
06:20 If you're in the mainland of Australia, you might hear them being fed at night.
06:25 And although they're solitary creatures, they can manage to tolerate each other's
06:30 presence while feeding.
06:31 And even during their feast, they have the worst-sounding conversations.
06:42 No one taught them table manners so they don't stop with their teeth baring and lunging when
06:47 they are eating.
06:48 Its screams are so iconic in all the wrong ways that the early settlers heard these screams
06:54 and decided that it definitely was the devil himself.
07:02 Unfortunately they've been classified as endangered now and have been impacted by a
07:07 cancer called the devil facial tumor disease.
07:13 Mantis shrimp punches at the speed of a bullet.
07:16 Saying that the mantis shrimp packs a punch is not very accurate because it doesn't
07:21 pack a punch, it packs a .22 caliber bullet.
07:25 This shrimp isn't even a shrimp, it's actually a distant relative of lobsters and crabs.
07:31 And at first sight, they seem like a beautiful mesh of vibrant colors.
07:35 Just because they look like a hot mess of colors doesn't mean they're just looks.
07:40 In fact, when they're threatened, they whip out their appendages at the speed of 75 feet
07:45 per second.
07:46 That's literally 50 times faster than you can blink.
07:55 These creatures are barely a few inches big and the blow they deliver is about 15,000
07:59 newtons.
08:00 The scientists who were studying them bought their cameras weren't even that advanced.
08:05 You can tell they were a lot of demand.
08:08 After a few expensive purchases, scientists realized that these shrimps practically have
08:12 a saddle-shaped structure with words like bow and arrow and the muscles pulling away
08:18 to bend it like an archer's bow.
08:20 He's absolutely ready.
08:22 He is keen and he is ready.
08:24 Look at him.
08:25 Look at those eyes.
08:26 They transfer all the energy into the club.
08:29 Safe to say that the octopus should not have gone near the shrimp.
08:33 A final merrile spread reminds him, never judge a creature by its looks again.
08:41 Giraffes fight with their necks aggressively.
08:44 If these giraffes were at a punk band concert, they'd be winning at the whole head-banging
08:48 thing.
08:49 But that's not what's going on here.
08:51 Usually everyone thinks giraffes are gentle creatures, just going around eating leaves
08:56 and all, but this is proof that they'll do anything for dominance.
09:06 When they come neck to neck, literally it's a test of their strength.
09:10 The giraffe with the thicker and the stronger neck usually wins the fight.
09:14 They start with bagging their necks and then they start twisting and aggressively rubbing
09:18 their necks.
09:19 This might seem cute if it's not too aggressive, but just know that it's them fighting in their
09:25 weirdest way possible.
09:27 Usually these rounds of necking can last up to half an hour and they usually don't stop
09:32 until one of them gets severely injured or even dies.
09:42 The female giraffes aren't involved in any of this.
09:45 They just sit back and watch them.
09:47 And sometimes the female giraffes get so aroused by the sledgehammer-style fighting that the
09:52 males leave what they're doing and, um, move on to other more important tasks.
10:02 Pufferfish makes art in sand to mate.
10:05 Fish don't do anything when they have to mate.
10:07 They just go over to a suitable partner and get at it.
10:11 But the white-spotted pufferfish needs to impress the ladies first.
10:15 These pufferfish areas are actually known for their unique courtship display.
10:20 And unlike birds, it's not a pretty dance that they do.
10:23 Instead, the pufferfish creates large and geometric circles in the sand.
10:27 They must maintain their circles until they attract a mate.
10:30 The female will come over and then evaluate its structure and then decide if the male
10:35 is worth mating with.
10:36 That's like a human judging if they're "worth" getting along with based on your
10:41 drawings.
10:42 And if you're a bad artist, well, there's no hope for you.
10:45 These circles were noticed by divers in 1995, only a few decades ago.
10:51 There are only species that do this type of dating ritual because literally no other fish
10:56 can do this.
10:58 But what could the female pufferfish judge from these mere sand circles?
11:02 There's one theory that suggests that the bigger the pufferfish, the easier it will
11:06 be to push sand.
11:07 So that might be the reason, but nothing is really sure.
11:12 Lemurs get intoxicated on millipedes.
11:14 You know how cats get high on catnip?
11:16 Well, this is somewhat similar.
11:19 Here we have lemurs, the stoners of the animal kingdoms.
11:22 These creatures have a bad habit of biting millipedes just to suck out the part that
11:27 gives them a chemical high.
11:29 When millipedes are picked up, their defense mechanism is to curl into a coil.
11:34 They have glands in their legs that secrete a toxic combination of chemicals, including
11:39 cyanides.
11:41 But this stuff doesn't kill the lemurs.
11:43 Instead, the lemurs rub this all over their fur.
11:46 Some research suggests that this works as a natural pesticide, which helps ward off
11:51 mosquitoes, and also acts as a narcotic.
11:54 That's definitely a plus.
11:56 Luckily, the millipedes get to leave completely unscratched, only to be found by the next
12:01 lemur.
12:03 Komodo dragon hug fight Animal fights are common, and they fight for
12:06 a number of reasons like dominance or mating.
12:10 But some animals take these rituals to a whole new level, and one of them is the Komodo dragon
12:15 who hugged the most in the animal kingdom.
12:18 Well, hugging is usually always a display of affection, but that only applies to humans,
12:24 and not Komodo dragons.
12:25 These dragons might look like they're sharing a loving hug, or even mating, when in fact
12:30 they're fighting for dominance.
12:32 This wrestling ritual ends up with one of them falling to ground and getting beat up.
12:37 Ouch!
12:38 Talk about tough love.
12:40 Scorpions glow in the dark for no apparent reason.
12:43 Scorpions, as they are, are pretty mysterious creatures.
12:46 But one thing that makes them even cooler is that they glow in the dark.
12:51 If you want to find a few for whatever reason, just grab a UV light and go into the desert
12:56 in the middle of the night.
12:58 If you see a stinky animal with a blue-green light, then you've found your insect.
13:03 Here's the part that doesn't make sense.
13:06 No one knows why scorpions glow.
13:08 Some researchers think that it is accidental.
13:16 It could be because of two chemicals that are the byproducts of natural reactions that
13:20 they can mix to make this fun glow.
13:22 However, others propose that this could be to lure in prey, which doesn't make too much
13:33 sense since insects avoid anything fluorescent, especially scorpions.
13:39 Another theory is that the glow could warn other predators or help their own kind recognize
13:44 each other.
13:46 Researchers think that these creatures collect UV light from the environment and create that
13:50 glow.
13:51 These signals could then pass to the brain, and this glow could increase the surface area
13:56 of its eye by literally a thousand times.
13:59 If this works out, this means that the entirety of a scorpion would work as one huge eye.
14:05 Pretty wacky.
14:06 Why do dolphins swim near boats?
14:09 Dolphins are often cited as the second smartest animals on Earth due to their relatively high
14:14 brain-to-body size ratio, the capacity to show emotion, and impressive mimicry of the
14:20 dumb apes who research them.
14:22 Why, despite our frequent cruelty to them, dolphins seem to actively seek out encounters
14:27 with humans?
14:28 Are they trying to tell us something?
14:30 Let me explain.
14:32 Dolphins are intelligent, playful animals that are often seen leaping from the waves
14:36 as they swim alongside ships at sea.
14:39 If dolphins are swimming nearby, does that mean there are sharks nearby?
14:44 It's a common piece of surfing wisdom that when dolphins swim, there are never sharks.
14:49 But if you see dolphins more often than not, there might be sharks in that same area.
14:53 That's because sharks and dolphins, both of whom are carnivores, go to the same spots
14:58 to hunt.
14:59 Another reason is dolphins love to have fun, whether it's jumping into the air, cruising
15:04 through the air at high speed, or interacting with other sea life.
15:08 Dolphins have shown a streak of fun-loving behavior that indicates many things they do
15:12 are simply for enjoyment's sake.
