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

2
00:00:07,889 --> 00:00:09,130
Let's watch it!

3
00:00:10,630 --> 00:00:15,490
Look, last week we explained what is a vertebrate animal.

4
00:00:15,949 --> 00:00:21,010
We said that a vertebrate animal is an animal that has a spine, ok?

5
00:00:21,350 --> 00:00:23,170
So this is the reason why.

6
00:00:23,730 --> 00:00:27,250
These animals here are vertebrates.

7
00:00:27,250 --> 00:00:35,579
We also said that humans are invertebrate animals. We have a spine.

8
00:00:38,200 --> 00:00:43,619
Look, these are examples of invertebrate animals. They don't have a spine.

9
00:00:46,500 --> 00:00:54,259
Last week we discovered mammals, birds, reptiles and amphibians.

10
00:00:54,259 --> 00:01:04,170
This week we are also going to study fish and invertebrate animals.

11
00:01:04,870 --> 00:01:12,930
Do you remember mammals? We said that mammals usually have four legs and hair.

12
00:01:13,569 --> 00:01:17,450
They drink their mother's milk and they are viviparous.

13
00:01:18,390 --> 00:01:26,989
We said that birds are vertebrates, they are oviparous, they have wings and most birds can't fly.

14
00:01:27,769 --> 00:01:30,849
Birds have two legs and feathers.

15
00:01:30,849 --> 00:01:38,950
We also discovered the reptiles. We said that they are oviparous, they have scales,

16
00:01:38,950 --> 00:01:48,370
and some reptiles can slither. We talked about amphibians and we said that they are vertebrates,

17
00:01:48,370 --> 00:01:56,170
they are oviparous, they lay eggs in the water, they have wet skin, and most amphibians have

18
00:01:56,170 --> 00:02:06,379
four legs now let's talk about fish fish are vertebrates they are oviparous they

19
00:02:06,379 --> 00:02:15,620
lay eggs in water fish can swim and they also have fins and scales look this is

20
00:02:15,620 --> 00:02:21,800
a fin another one another one another one and another one but scales what is

21
00:02:21,800 --> 00:02:28,340
scale. Can you remember the reptiles? Reptiles have scales too. Look at this

22
00:02:28,340 --> 00:02:40,539
here. All these small parts are scales. Now and finally, invertebrates. We said

23
00:02:40,539 --> 00:02:46,199
that invertebrates don't have a spine, they don't have a backbone. Now we are

24
00:02:46,199 --> 00:02:54,939
going to talk about insects. Insects are a kind of invertebrate animals. Look, we have an ant

25
00:02:54,939 --> 00:03:02,879
and we have a butterfly. So, insects are invertebrates. They don't have a backbone.

26
00:03:03,659 --> 00:03:14,280
Insects are a viperus. Insects have six legs. Some insects can fly. So, six legs. Let's count.

27
00:03:14,280 --> 00:03:20,919
One, two, three, four, five, six legs

28
00:03:20,919 --> 00:03:24,500
Yes, insects have six legs

29
00:03:24,500 --> 00:03:28,099
And look at the wings of the butterfly

30
00:03:28,099 --> 00:03:31,360
Have you seen a butterfly flying?

31
00:03:31,840 --> 00:03:33,419
Yes, of course you have

32
00:03:33,419 --> 00:03:35,560
So this is it

33
00:03:35,560 --> 00:03:38,000
This is the end of this video

34
00:03:38,000 --> 00:03:39,360
See you next week

35
00:03:39,360 --> 00:03:39,919
Bye
