00:00:00,370 --> 00:00:04,870
Today we are going to learn about vertebrate animals.

2
00:00:05,889 --> 00:00:09,929
Animals can be vertebrate or invertebrate.

3
00:00:10,609 --> 00:00:13,990
Vertebrate animals have got a skeleton.

4
00:00:14,710 --> 00:00:16,429
They have got bones.

5
00:00:18,050 --> 00:00:22,250
Whereas invertebrate animals haven't got a skeleton.

6
00:00:23,890 --> 00:00:24,510
Mammals.

7
00:00:25,510 --> 00:00:27,149
Mammals are baby birds.

8
00:00:27,149 --> 00:00:29,890
They are born from their mother's belly.

9
00:00:30,370 --> 00:00:49,049
Babies drink milk. They have fur and a backbone. Mamas are warm-blooded. There are very different types of mamas, such as humans, cows, dolphins, or bats.

10
00:00:49,049 --> 00:01:09,849
Birds are oviparous. They lay eggs. Birds have got a beak, feathers, and wings. They are warm-blooded. One example of a bird is a parrot.

11
00:01:09,849 --> 00:01:17,269
Reptiles. They are oviparous. They lay eggs.

12
00:01:18,269 --> 00:01:25,530
They are cold-blooded animals, which means their temperature varies depending on where they are.

13
00:01:26,090 --> 00:01:31,769
They have got scales and some of them have got a shell.

14
00:01:32,909 --> 00:01:38,069
Some examples are the turtle, crocodile and snake.

15
00:01:38,069 --> 00:01:41,620
Amphibians

16
00:01:41,620 --> 00:01:44,319
They are oviparous

17
00:01:44,319 --> 00:01:47,420
They are born from eggs

18
00:01:47,420 --> 00:01:50,219
When they are young, they live in water

19
00:01:50,219 --> 00:01:55,200
And when they are adults, they can live in water and on land

20
00:01:55,200 --> 00:01:57,959
And their aspects change

21
00:01:57,959 --> 00:02:01,599
They are cold-blooded animals

22
00:02:01,599 --> 00:02:06,060
Which means their temperature varies depending on where they are

23
00:02:06,060 --> 00:02:07,799
Example

24
00:02:07,799 --> 00:02:08,740
A frog

25
00:02:08,740 --> 00:02:13,699
Fish. Fish are oviparous animals.

26
00:02:14,699 --> 00:02:16,639
They are born from eggs.

27
00:02:17,479 --> 00:02:23,960
They live in water and they can live in salt water and in fresh water.

28
00:02:24,360 --> 00:02:29,879
They have got scales and they are cold-blooded,

29
00:02:30,199 --> 00:02:36,180
which means their body temperature changes depending on the water.

30
00:02:37,259 --> 00:02:38,060
An example.

31
00:02:38,740 --> 00:02:39,639
A shark.
