1 00:00:00,240 --> 00:00:07,120 Hello kids! Today we're going to talk about animals. Do you like animals? What's your favorite 2 00:00:07,120 --> 00:00:18,079 animal? Do you like elephants, octopus, cats, dogs? Whatever animal that you can think of, 3 00:00:18,079 --> 00:00:25,920 you can put into a category. You can put it into a category based on whether or not it has 4 00:00:25,920 --> 00:00:34,399 a backbone you can put it in a category based on what it eats you can put it in a category 5 00:00:34,399 --> 00:00:40,960 based on how they carry their babies and you can put it in a category based on how they look 6 00:00:40,960 --> 00:00:47,039 and how they're related to other animals so today we're going to talk about a few different 7 00:00:47,039 --> 00:00:54,479 categories that you can put animals into so first we're going to talk about animals that have 8 00:00:54,479 --> 00:01:00,359 a backbone. So remember we learned backbone is this right here. So if you 9 00:01:00,359 --> 00:01:09,120 have a backbone you are a vertebrate. So we humans are vertebrates. There are five 10 00:01:09,120 --> 00:01:16,799 different groups of vertebrates. The first group are mammals. Mammals have 11 00:01:16,799 --> 00:01:25,680 fur and they carry their babies inside. So humans, we are mammals. If you have a 12 00:01:25,680 --> 00:01:36,359 cat or a dog at home, that's a mammal. Next are birds. Birds have wings and they 13 00:01:36,359 --> 00:01:46,379 can fly. Unlike mammals like us that have fur or hair, birds have feathers. Birds 14 00:01:46,379 --> 00:01:55,459 also have a beak, a beak that they use to break their food. So nuts and seeds and worms, they use 15 00:01:55,459 --> 00:02:02,859 their beak. The next type of vertebrate are reptiles. So reptiles are like iguanas and 16 00:02:02,859 --> 00:02:12,199 lizards. They have very dry skin and scales. So they don't have skin like humans, like we do. 17 00:02:12,199 --> 00:02:21,319 They have scales. The next category are amphibians. Amphibians have moist skin 18 00:02:21,319 --> 00:02:29,340 because they spend a lot of their lives in water. They also go on land. So amphibians are born in 19 00:02:29,340 --> 00:02:38,560 the water. The most popular amphibian is a frog. And the last type of vertebrate is a fish. So like 20 00:02:38,560 --> 00:02:48,159 reptiles fish have scales but fish don't live on land fish live under water fish have fins 21 00:02:48,719 --> 00:02:55,759 so that they can swim they have gills so they don't breathe air like us they have gills 22 00:02:56,560 --> 00:03:02,719 to take in oxygen from the water and then last they have a tail in the back which like their 23 00:03:02,719 --> 00:03:10,840 fins helps them swim. So we talked about how we can put animals into categories based on whether 24 00:03:10,840 --> 00:03:16,659 or not they have a backbone. So if they have a backbone, they're a vertebrate. If they don't 25 00:03:16,659 --> 00:03:23,020 have a backbone, they're an invertebrate. And then within the vertebrates, we can separate them into 26 00:03:23,020 --> 00:03:29,439 categories based on their characteristics of their body. Now we're going to talk about putting 27 00:03:29,439 --> 00:03:37,780 animals into categories based on what they eat. So we have three categories based on what animals 28 00:03:37,780 --> 00:03:49,439 eat. Herbivore, carnivore, and omnivore. The first herbivore. An herbivore is an animal that only 29 00:03:49,439 --> 00:03:59,780 eats plants. So an herbivore could be a panda or a zebra. They only eat plants. They don't eat 30 00:03:59,780 --> 00:04:08,759 meat. They don't eat other animals. Next are carnivores. Carnivores only eat meat. So a 31 00:04:08,759 --> 00:04:19,000 carnivore can be a lion or a crocodile. Carnivores don't eat plants. The last category are omnivores. 32 00:04:19,439 --> 00:04:24,439 Omnivores eat both plants and meat. 33 00:04:24,439 --> 00:04:30,439 An omnivore is a frog or us humans. 34 00:04:30,439 --> 00:04:42,439 Humans are omnivores because we eat plants, like vegetables, and we also eat meat, like beef or chicken or fish. 35 00:04:42,439 --> 00:04:48,800 Next, we can separate animals into categories based on how they have their babies. 36 00:04:49,379 --> 00:04:53,540 There are two different categories, viviparous and oviparous. 37 00:04:54,199 --> 00:04:58,839 So a viviparous animal has their babies inside them. 38 00:04:58,839 --> 00:05:02,980 So humans and other mammals are viviparous. 39 00:05:03,360 --> 00:05:05,720 They always have their babies inside them. 40 00:05:06,259 --> 00:05:08,779 Oviparous animals have babies in an egg. 41 00:05:08,779 --> 00:05:16,959 so they hatch an egg like a bird or chicken they hatch or they lay an egg and the egg hatches 42 00:05:16,959 --> 00:05:25,800 and that's where the baby comes from so remember viviparous inside and oviparous in an egg okay 43 00:05:25,800 --> 00:05:32,920 so remember how we separated different vertebrates into different categories let's talk about the 44 00:05:32,920 --> 00:05:40,060 characteristics of one type of vertebrate, birds. So we talked about how humans, as mammals, 45 00:05:40,459 --> 00:05:48,060 we have hair. So we have hair on our head, we have hair on our body. Birds don't have fur. 46 00:05:48,519 --> 00:05:55,360 They don't have hair. Instead, on their bodies, they have feathers. This makes them lighter and 47 00:05:55,360 --> 00:06:03,660 easier to fly. They also have wings so that they can fly. Humans don't have wings. Instead of a 48 00:06:03,660 --> 00:06:10,279 mouth like humans have, birds have a beak. They have a beak and this makes it easier for them to 49 00:06:10,279 --> 00:06:16,459 crack nuts and seeds to eat and also pick worms out of the ground depending on what type of bird 50 00:06:16,459 --> 00:06:23,620 it is and what type of food they eat. Birds are oviparous so they lay eggs. They don't have their 51 00:06:23,620 --> 00:06:29,220 babies inside. They lay an egg, the egg hatches, and then they have their baby. 52 00:06:29,220 --> 00:06:36,519 Birds also have a tail. Humans don't have a tail. Birds have a tail and this makes 53 00:06:36,519 --> 00:06:41,779 flying much easier for them. Okay, so that's enough animals for today. See you 54 00:06:41,779 --> 00:06:43,980 later!
