5 Amazing Animals!

[Music] it's Valentine's Day I was just about to check the mailbox to see if we got any Valentines from our friends Wow squeeks we got a whole bunch let's read them the first one is sort of wet oh no wonder it came from our friend Mickey the Green Line shark let's read it roses are red the ocean is blue I lost all these teeth but I'm glad I found you that's so sweet sharks are awesome and this video has some amazing facts about them when you think of a shark what do you picture in your mind do you think of a big fin sticking out of the water or maybe a huge set of sharp teeth sharks are some of the most famous animals in the ocean but do you know what makes a shark a shark well for one thing all sharks are fish that might not surprise you since they live and swim in the water but sharks are a special kind of fish one of the things that makes them different from other fish like goldfish is that sharks have a special skeleton our skeletons are made of bone and so are the skeletons of most kinds of fish but a shark's skeleton isn't made of bone it's made of cartilage and you have cartilage in your body too you can feel it right now touch the tip of your nose wiggle it around how does it feel what about your ear can you bend it you sure can because the tip of your nose and your ear aren't filled with bone they're filled with cartilage cartilage is a lot lighter than bone and it bends easily so having a skeleton made of this stuff helps sharks swim farther and faster than if their skeletons were made of bone now let's look at another body part that sharks are famous for their teeth have you ever lost a baby tooth and then an adult tooth grew in well sharks lose their teeth all the time throughout their entire lives and they just keep growing new ones how can they do that you and I just have one row of teeth in our mouth but sharks have lots of rows of teeth on the top and the bottom so when a shark loses a tooth another tooth that's right behind it can just move on up to take its place because they always have new teeth to replace the old ones some sharks can lose thousands of teeth during their lives our the next cool thing about sharks their skin if you could rub the skin of a shark you'd find that it would feel smooth if you ran your hand in one direction but if you rubbed your hand the other way it would feel rough like a cat's toe that's because a shark's skin is covered in tough bony scales that actually look a little like tiny teeth these little scales are stacked on top of each other like tiles on a roof this helps sharks swim through the water quickly and quietly so those are some of the things that all sharks have but there are over 450 types of sharks in the world and that means a lot of differences to take a look at this one it's called a whale shark and it's the biggest shark there is in fact it's the largest fish in the whole world whale sharks can grow to be as long as a school bus but even though they're so big they eat tiny plants and super small animals called plankton that float in the water but not all sharks are as big as the whale shark some can also be tiny meet the dwarf lanternshark it's so small then it could fit in my hand this shark lives in the deep ocean where there's very little light so it has big eyes to help see in the dark plus it has a really neat feature yes special organs on its belly fins and tail that actually glow I just think this might help the lantern shark lure and prey for it to eat plus when it's in shallower water where there's more light these blowing lights can help it blend in to avoid predators finally I'd like you to meet a very special shark say hello to the Greenland shark this big shark spends most of its time swimming in very cold water hanging out near the sea floor looking for an easy snack but scientists have recently discovered something amazing about these animals Greenland sharks can live to be up to 400 years old of all the animals in the world with backbones known as vertebrates Greenland sharks live the longest at least that we know of but scientists are still discovering new kinds of sharks all the time so who knows what kinds of super sharks are still out there waiting to be found oh this next one is from a the giant panda all the way from Szechuan China oh look squeaks she sent us candy - oh man oh it's bamboo let's read the card there once was a panda so where we could barely find it a pair but if you'll be its mate boy that would be great what better friends than a bear Mei is a great friend and I'm glad people are helping the pandas in this next video we talked about why pandas have a problem and how people can help I'm thinking of an animal it's black and white furry and kind of looks like a teddy bear you're right squeaks it's a panda kids all over the world have heard of pandas but have you ever seen one if you're lucky you may have seen one in a zoo but I'm pretty sure you've never come across one just walking around that's because pandas are very rare and we can learn a lot from them about what all kinds of animals need to survive in the wild the animals you and I know as pandas are actually called giant pandas and they're bears in the same family as brown and black bears and pandas like all animals need certain things to live like food water and a place to sleep and be safe we call the place where an animal has all of these things that it needs to live its habitat the place where you live is your habitat but let's find out what a panda's habitat looks like all pandas that live in the wild that is they aren't in zoos can be found in the mountains of China the weather there is cool and wet and the forests in these mountains make up the pandas habitat can just make their homes called dens in places like the stumps of old trees or inside big hollow logs so these mountain forests give pandas a place to sleep and be safe but a habitat also needs to provide food for the animals that live there and the pandas favorite food by far is a plant called bamboo pandas eat a lot of bamboo and quickly they have to eat a lot to get as big as they do but the problem with a pandas diet is they don't eat much else the fact is they're very picky eaters so a pandas habitat has to have a lot of bamboo growing in it luckily the cool wet forests of China are a great place for growing bamboo all in all these forests are the perfect habitat for pandas but there is a problem the pandas habitat is getting smaller a long time ago there used to be a lot of mountain forests for the bears to live in but people started to cut down a lot of the forest to make room for buildings and to use the wood for fuel as they did this the pandas habitat got smaller and separated into pieces pandas started to have problems finding enough food to eat and safe places to have their babies and as their habitat got smaller so did the number of pandas so today there are far fewer pandas than there were a long time ago scientists think that there are fewer than 2,000 pandas living in the wild today but there is good news once people learned that pandas were in trouble they start to do things to help them people aren't allowed to cut down the trees in the pandas habitat anymore and scientists and volunteers have planted bamboo and trees to try and make the pandas habitat bigger again it's hard work but lots of people are trying to solve the problem so pandas are already famous for being cute and cuddly but they're also a great example of how all animals need a healthy habitat in order to survive and how sometimes we can help protect it for them ha this next one has got to be from Dino from the tip of my nose to the tip of my tail I've got Dino size love that could tip all the scales can you tell how much Dino likes dinosaurs remember when he came by and taught us all about them okay guys we invited a friend over to hang out today he's a lot of fun his name is Dino and he loves dinosaurs he has all kinds of dinosaur costumes it's true dinosaurs are so cool and who are you wearing today do you know t-rex my favorite dinosaur right now is actually the ankylosaurus but they had four legs so that costume is kind of awkward let's got grape juice on it so my dad has to wash it well I think you look great you might already have guessed this but Dino knows all sorts of things about dinosaurs I love reading about them I read all the books about them in the library well why don't you tell us a little bit about what you've learned so far maybe you can start with this what makes a dinosaur a dinosaur hey good question Jessie there were all kinds of dinosaurs that lived millions of years ago some had two legs like t-rex here and some had four legs like ankylosaurus some ate plants and some ate other animals but they all had a few things in common like what well one way to tell whether an animal is really a dinosaur or not is look at its legs its lakes really yeah let me show you first have a look at this guy it's a komodo dragon it's the biggest lizard in the world today it lives on some islands in Asia but Komodo here isn't really a dragon it's a reptile it has scaly skin and a long tail and I can totally see how some people might think it looks kind of like a dinosaur but look at its legs its legs stick out from the sides of its body so its feet are out on the sides - almost like it's doing push-ups okay I see what you're talking about there but how does it dinosaurs legs look well have a look at this skeleton of a Stegosaurus this fella lived in North America millions of years ago and its feet are directly underneath it dinosaur's legs were kind of like posts or pillars that held up their heavy bodies if their legs stuck out to the sides they wouldn't be able to stand up so dinosaurs had their feet directly underneath them while other reptiles like lizards and alligators and Komodo dragons have legs and feet that stick out to the sides not that there's anything wrong with that I mean some of my best friends are lizards and alligators they're just not dinosaurs cool I've learned something already well how else could you tell if an animal that lived a long time ago was a dinosaur a lot of things that dinosaurs had in common weren't so much about how they looked but about how they lived for example dinosaurs only lived on land they didn't live in water and they couldn't fly couldn't fly really really you've probably seen pictures of an animal like this before right they were amazing flying reptiles and they lived back in the time of the dinosaurs but they weren't dinosaurs they were pterosaurs a whole different type of ancient reptile unlike the dinosaurs they had hollow bones and big flaps of skin like wings which they used to fly they also had really long narrow skulls with big brains inside but dinosaurs didn't have any of those things I mean I've never seen a t-rex with the wings of you know no I can't say that I have but you also said that dinosaurs didn't live in the water nope they only lived on land there were all kinds of huge reptiles that lived in the oceans back in dinosaur times but none of them were dinosaurs they were different in a lot of ways like some were called pleasee Oh sores and didn't lay eggs like dinosaurs did they just gave birth to live babies can you believe that and another kind of swimming reptile were the mosasaurs they were actually related more to snakes men to dinosaurs just like snakes they can open their mouths so wide that they could actually eat things that were bigger than their own heads kind of wish I can do that especially with apples I love of me some apples so I can see from the fins and flippers on these swimming reptiles if they were adapted to life in the water so if I see a fossil or a picture of a reptile that lived a long time ago that has fins and flippers I know it's not a dinosaur right that's right Jesse dinosaurs lived only on land and stood with their feet right under them instead of to the sides got it thanks for sharing what you've learned with us Dino Oh believe me Jesse I could go on all day oh I bet you could all right what's next hi Jesse hi Sam what are you doing here well I'm glad you asked see in addition to being an excellent astronomer I'm also an excellent poet and I wrote a poem that I wanted to share with everybody may I read it of course you can I can't wait to hear it one second okay I have eaten the bugs that were in the forest and which you are probably saving for morning forgive me they were delightful so sweet and so crunchy thank you that was great Sam and as my valentine to you here's a whole bunch of cool stuff about bats I'm thinking of an animal it's small and furry it could be pretty cute and it flies around at night can you guess what animal it is that's right I'm thinking about bats some people think bats are scary maybe because they only come out at night or maybe because sometimes they live in dark places or maybe it's because some species of bats called vampire bats survive by drinking blood but you probably won't ever run into a vampire bat only three species of bat are blood drinkers the rest of them over 1,200 species eat fruit nectar bugs and other small animals if you ask us bats are totally awesome here are just three of our favorite things about them to start some asking here their way in the dark that's because they don't rely on their eyes like we do instead bats use sound to find their way around have you ever yelled into a big empty room or a canyon and hurt your own voice shout back at you that's called an echo the sound of your voice moves across the room to the walls and then bounces back to your ears as a bat flies through the night it does something really similar it makes a sound and then carefully listens for the echo and the way the echo comes back can tell the bat a lot about what found it this special skill is called echolocation if the echo comes back quickly that means there must be something pretty close to it because the sound only travels a short way before bouncing back but if the echo takes a long time to bounce back then the bat knows that the object is further away bass can tell not only how far away something is but also how big it is and how fast it's moving all from using echolocation and since bats are constantly using echolocation to figure out the world around them you'll often see them flying around with their mouths open to keep making sounds to bounce back another thing we like about bats they really like to hang out bats hang upside down in quiet dark hidden places like the roof of a cave or the underside of a bridge but how when I hang upside down from the monkey bars after a while I start to feel like my head is going to explode bat can hang for a long time because their bodies are built for life upside down the little pathways in their bodies that blood moves through called arteries have special valves in them that only let blood through one way as the bats heart beats the blood has to keep moving through its body in just one direction that keeps the blood from getting stuck in the bats head when it's hanging upside down that's a pretty neat trick but you know another thing that's easy to like about bats they make really great moms bets usually have one baby called a pup in a year at the beginning of that pups life it clings to its mother's belly all the time while the mom wraps her wings around it maybe we should stop calling good snuggles bear hugs and start calling them fat hugs and thousands of moms and their pups can live together in a huge group called a nursery even when it's cold outside the nursery stays warm because of all those bats hanging close together plus when Mom needs to go out and find food she can just drop her baby off at the nursery with all the other moms and pups when she comes back you might think it'd be hard to find her baby again I mean there are thousands of pups that look just like hers but bats and their pups can recognize each other through their smells and their voices so when a pup called out the mom can fly right to it it would be like trying to find your family in the middle of a crowded amusement park except all of the other kids at the park are calling out for their parents - so what do you think are bats scary cool ok there's one left and it's from you squeaks oh what a great surprise whenever I get hungry I look around for snacks grains and fruits and vegetables and even Cracker Jacks left and right are lots of things on which little rats can dine but it doesn't matter what we eat dear as long as you are mine oh that's super cute tink squeaks I really like you too and I really like rats do you remember when we learned all about them today is a date that squeaks has been looking forward to for a long time that's because today we're going to learn all about rats what do you think of rats you might think of animals that live in creepy places like empty buildings or dark alleys or even sewers but rats make their homes in lots of places from deep underground to high up in trees in fact a lot of what people think they know about rats isn't true at all so squeaks and I thought it would be fun to play a little game I'll say something about rats and then you guess whether that sentence is true or false then squeaks can tell us the right answer you ready let's play true or false rats are dirty animals what do you think false rats are actually very clean rats lick their fur to keep it clean they also lick their paws and then use them to clean their faces and whiskers when animals clean themselves like this it's called grooming and rats groom a lot they sometimes clean themselves even more than cats do people often think rats are dirty because some rats can carry diseases that make us sick so while rat isn't dirty if you see a rat running around where you live or think there might be one you should leave it alone and tell a grown-up ok let's try another one true or false rats like to swim hmm that's a tough one this one is definitely true rats are really good swimmers scientists have learned that wrath can tread water or swim in one place for up to three whole days without a break that's awesome they're good at swimming along distances too rats can swim almost a kilometer without stopping and they can hold their breath for about three minutes that's way more than you could okay let's try another one true or false rats have excellent eyesight do you know this one is false rats can't see very well at all but they make up for it using their other's senses to stay away from predators to find food and to find their way around take for example a rat sense of smell a rat's nose is so sensitive then it can learn about another rat just by smelling it like whether it's sick or not rats have even been known to smell each other's breath to see what they've been eating that way if a rat smells that smell again it knows that whatever's making that smell is good to eat a rats hearing is also excellent try this hold your hand in front of your face and gently rub your pointer and thumb together can you hear anything a rat Ken noises that we can't hear or can't hear very well can sound perfectly clear to a rat okay here's another good one true or false rats can chew through cement whoa now that sounds extraordinary do you think it's true or false believe it or not this one is true a rats mouth has everything it needs to chew through some really hard stuff rats belonged to a group of animals called rodents rodents use their incisors or their front teeth to bite and like all rodents a rats incisors never stop growing rasz need to chew on things to keep them from getting too long so rats chew and chew and chew a lot the Front's of a rats incisors are harder than your teeth they're even harder than some metals like copper and iron but these extra hard teeth are only one thing that makes a rat a champion Scheuer put your fingers on either side of your face just in front of your ears and below your cheek bones now open and close your mouth can you feel those muscles move these muscles move your jaw the bottom part of your mouth rats have special jaw muscles that help them bite and they can bite hard rats can bite down harder than a great white shark so between their strong jaw muscles and hard teeth rats can chew through wood metal plastic and yes even cement all right let's try one more true or false rats are not very smart of course weeks this one is definitely false rats are pretty clever they can learn very quickly sometimes even faster than people can't they're also great at remembering things and they can solve problems like how to get where they want to go rats aren't only smart they're also kind to each other have been know to share food with other rats and have even been known to figure out how to open another rat's cage to set them free so I'm glad my best friend is a rat I want to thank all of our amazing friends for these great Valentines and I want to thank you for joining us today do you have any questions about the incredible animals we learned about today let us know grab a grown-up to help you leave a comment down below or send us an email to kids at scishow comm thanks for joining us and if you're celebrating it happy Valentine's Day [Music]
