Hello everybody and welcome to this new video of this unit that is called Animals. 00:00:00

Let's watch it! 00:00:07

Look, last week we explained what is a vertebrate animal. 00:00:10

We said that a vertebrate animal is an animal that has a spine, ok? 00:00:15

So this is the reason why. 00:00:21

These animals here are vertebrates. 00:00:23

We also said that humans are invertebrate animals. We have a spine. 00:00:27

Look, these are examples of invertebrate animals. They don't have a spine. 00:00:38

Last week we discovered mammals, birds, reptiles and amphibians. 00:00:46

This week we are also going to study fish and invertebrate animals. 00:00:54

Do you remember mammals? We said that mammals usually have four legs and hair. 00:01:04

They drink their mother's milk and they are viviparous. 00:01:13

We said that birds are vertebrates, they are oviparous, they have wings and most birds can't fly. 00:01:18

Birds have two legs and feathers. 00:01:27

We also discovered the reptiles. We said that they are oviparous, they have scales, 00:01:30

and some reptiles can slither. We talked about amphibians and we said that they are vertebrates, 00:01:38

they are oviparous, they lay eggs in the water, they have wet skin, and most amphibians have 00:01:48

four legs now let's talk about fish fish are vertebrates they are oviparous they 00:01:56

lay eggs in water fish can swim and they also have fins and scales look this is 00:02:06

a fin another one another one another one and another one but scales what is 00:02:15

scale. Can you remember the reptiles? Reptiles have scales too. Look at this 00:02:21

here. All these small parts are scales. Now and finally, invertebrates. We said 00:02:28

that invertebrates don't have a spine, they don't have a backbone. Now we are 00:02:40

going to talk about insects. Insects are a kind of invertebrate animals. Look, we have an ant 00:02:46

and we have a butterfly. So, insects are invertebrates. They don't have a backbone. 00:02:54

Insects are a viperus. Insects have six legs. Some insects can fly. So, six legs. Let's count. 00:03:03

One, two, three, four, five, six legs 00:03:14

Yes, insects have six legs 00:03:20

And look at the wings of the butterfly 00:03:24

Have you seen a butterfly flying? 00:03:28

Yes, of course you have 00:03:31

So this is it 00:03:33

This is the end of this video 00:03:35

See you next week 00:03:38

Bye 00:03:39
