MAMMALS

1
00:00:10,000 --> 00:00:15,000
The diversity of mammals is amazing.

2
00:00:15,000 --> 00:00:24,000
They can be as huge as these whales or as tiny as this cute little balancing mouse.

3
00:00:24,000 --> 00:00:31,000
They can be noisy like this howler monkey or quiet like this hedgehog with its sharp

4
00:00:31,000 --> 00:00:34,000
pointy spines.

5
00:00:34,000 --> 00:00:39,000
Even though they're amazingly diverse, all mammals have a number of common characteristics

6
00:00:39,000 --> 00:00:44,000
you should know about so you can recognize and differentiate them.

7
00:00:44,000 --> 00:00:47,000
All mammals are viviparous.

8
00:00:47,000 --> 00:00:50,000
They are born from their mother's womb.

9
00:00:50,000 --> 00:00:56,000
In their early stages of life, they feed on milk which they get from their mother's breasts

10
00:00:56,000 --> 00:01:01,000
where the mammary glands are and that's why they're called mammals.

11
00:01:01,000 --> 00:01:04,000
And when they're little, they're so cute, aren't they?

12
00:01:21,000 --> 00:01:29,000
Mammals reproduce by internal fertilization when a sperm cell and an egg join inside a

13
00:01:29,000 --> 00:01:32,000
female.

14
00:01:32,000 --> 00:01:41,000
As you can see, they have teeth inside their mouths and lips around them so they can eat

15
00:01:41,000 --> 00:01:45,000
and suck milk.

16
00:01:45,000 --> 00:01:54,000
Most mammals' bodies are covered with hair and all mammals breathe with their lungs even

17
00:01:54,000 --> 00:01:58,000
if they live in the sea.

18
00:01:58,000 --> 00:02:05,000
Look at these dolphins coming up to the surface for air.

19
00:02:05,000 --> 00:02:11,000
The body temperature of mammals doesn't depend on whether it's cold or hot outside because

20
00:02:11,000 --> 00:02:16,000
they can maintain their own internal temperature.

21
00:02:16,000 --> 00:02:23,000
Almost all mammals are terrestrial like camels and jaguars.

22
00:02:23,000 --> 00:02:30,000
Some live in the sea and are called marine mammals like these dolphins and these seals.

23
00:02:30,000 --> 00:02:32,000
There's even a flying mammal.

24
00:02:32,000 --> 00:02:42,000
Bats are the only mammal that flies.

25
00:02:42,000 --> 00:02:48,000
Mammals have four limbs which vary depending on where they live.

26
00:02:48,000 --> 00:02:56,000
Land mammals have legs so they can walk and run when they need to and jump and sometimes

27
00:02:56,000 --> 00:02:59,000
even climb.

28
00:02:59,000 --> 00:03:08,000
Wind mammals have fins so they can swim very fast.

29
00:03:08,000 --> 00:03:13,000
Flying mammals have wings so they can fly through the sky.

30
00:03:13,000 --> 00:03:18,000
Do you know which is the most wonderful mammal that lives on Earth?

31
00:03:18,000 --> 00:03:20,000
Human beings!

32
00:03:20,000 --> 00:03:24,000
People are mammals too.

33
00:03:24,000 --> 00:03:26,000
How mammals feed.

34
00:03:26,000 --> 00:03:31,000
Depending on what they eat, mammals can be classified into different groups.

35
00:03:31,000 --> 00:03:37,000
Herbivores only eat plants and their teeth are especially designed for grinding.

36
00:03:37,000 --> 00:03:45,000
Horses, sheep and llamas are herbivorous animals.

37
00:03:45,000 --> 00:03:48,000
Some very special herbivores are called ruminants.

38
00:03:48,000 --> 00:03:54,000
They swallow their food almost without chewing it and some of it is digested normally but

39
00:03:54,000 --> 00:04:00,000
some of it is stored in their stomach and when they want to they regurgitate it into

40
00:04:00,000 --> 00:04:03,000
their mouth to digest it again.

41
00:04:03,000 --> 00:04:07,000
Cows, giraffes and goats are ruminants.

42
00:04:07,000 --> 00:04:14,000
Carne means skin or meat in Latin and that's what carnivores eat, the flesh of other animals.

43
00:04:14,000 --> 00:04:20,000
Their teeth are large and sharp for hunting and tearing at their food.

44
00:04:20,000 --> 00:04:29,000
Mammals that eat insects and other invertebrates are called insectivores like these anteaters.

45
00:04:29,000 --> 00:04:33,000
Omnivorous mammals feed on both meat and plants.

46
00:04:33,000 --> 00:04:38,000
Bears, monkeys and humans are omnivores.

47
00:04:38,000 --> 00:04:43,000
We can eat a tasty burger with lettuce and tomato.

48
00:04:43,000 --> 00:04:48,000
So let's remember.

49
00:04:48,000 --> 00:04:53,000
Herbivores are viviparous and in the early stages of life they feed on milk from their

50
00:04:53,000 --> 00:04:55,000
mother's breasts.

51
00:04:55,000 --> 00:04:58,000
They have lips and breathe with their lungs.

52
00:04:58,000 --> 00:05:03,000
Their body temperature does not depend on the environment they're in and depending

53
00:05:03,000 --> 00:05:08,000
on their food sources they may be herbivores, carnivores or omnivores.

54
00:05:08,000 --> 00:05:10,000
Easy right?

00:05:10,000 --> 00:05:15,000
