MAMMALS 00:00:00
The diversity of mammals is amazing. 00:00:10
They can be as huge as these whales or as tiny as this cute little balancing mouse. 00:00:15
They can be noisy like this howler monkey or quiet like this hedgehog with its sharp 00:00:24
pointy spines. 00:00:31
Even though they're amazingly diverse, all mammals have a number of common characteristics 00:00:34
you should know about so you can recognize and differentiate them. 00:00:39
All mammals are viviparous. 00:00:44
They are born from their mother's womb. 00:00:47
In their early stages of life, they feed on milk which they get from their mother's breasts 00:00:50
where the mammary glands are and that's why they're called mammals. 00:00:56
And when they're little, they're so cute, aren't they? 00:01:01
Mammals reproduce by internal fertilization when a sperm cell and an egg join inside a 00:01:21
female. 00:01:29
As you can see, they have teeth inside their mouths and lips around them so they can eat 00:01:32
and suck milk. 00:01:41
Most mammals' bodies are covered with hair and all mammals breathe with their lungs even 00:01:45
if they live in the sea. 00:01:54
Look at these dolphins coming up to the surface for air. 00:01:58
The body temperature of mammals doesn't depend on whether it's cold or hot outside because 00:02:05
they can maintain their own internal temperature. 00:02:11
Almost all mammals are terrestrial like camels and jaguars. 00:02:16
Some live in the sea and are called marine mammals like these dolphins and these seals. 00:02:23
There's even a flying mammal. 00:02:30
Bats are the only mammal that flies. 00:02:32
Mammals have four limbs which vary depending on where they live. 00:02:42
Land mammals have legs so they can walk and run when they need to and jump and sometimes 00:02:48
even climb. 00:02:56
Wind mammals have fins so they can swim very fast. 00:02:59
Flying mammals have wings so they can fly through the sky. 00:03:08
Do you know which is the most wonderful mammal that lives on Earth? 00:03:13
Human beings! 00:03:18
People are mammals too. 00:03:20
How mammals feed. 00:03:24
Depending on what they eat, mammals can be classified into different groups. 00:03:26
Herbivores only eat plants and their teeth are especially designed for grinding. 00:03:31
Horses, sheep and llamas are herbivorous animals. 00:03:37
Some very special herbivores are called ruminants. 00:03:45
They swallow their food almost without chewing it and some of it is digested normally but 00:03:48
some of it is stored in their stomach and when they want to they regurgitate it into 00:03:54
their mouth to digest it again. 00:04:00
Cows, giraffes and goats are ruminants. 00:04:03
Carne means skin or meat in Latin and that's what carnivores eat, the flesh of other animals. 00:04:07
Their teeth are large and sharp for hunting and tearing at their food. 00:04:14
Mammals that eat insects and other invertebrates are called insectivores like these anteaters. 00:04:20
Omnivorous mammals feed on both meat and plants. 00:04:29
Bears, monkeys and humans are omnivores. 00:04:33
We can eat a tasty burger with lettuce and tomato. 00:04:38
So let's remember. 00:04:43
Herbivores are viviparous and in the early stages of life they feed on milk from their 00:04:48
mother's breasts. 00:04:53
They have lips and breathe with their lungs. 00:04:55
Their body temperature does not depend on the environment they're in and depending 00:04:58
on their food sources they may be herbivores, carnivores or omnivores. 00:05:03
Easy right? 00:05:08
