 There
are many mammals living on Earth. We are mammals, too. But what are
mammals? This week, let¡¯s learn all about mammals! There are many
fun facts about them. Keep reading and learn some new facts about
mammals!
Mammals are animals that are warm-blooded. Female mammals give birth to babies, not
eggs. And they feed their babies on milk
from their own bodies. Mammals are backboned animals. They are
found all over the world. So, how many kinds of mammals are there
in the world? There are about 4,260 kinds of them.
Humans, dogs, cats, elephants, and horses are all mammals. But birds,
fish and turtles are not. Interestingly, whales and
dolphins are not fish. Even though they live in
the ocean, they are mammals. Unlike other fish, they don¡¯t
lay eggs. Also, bats are
mammals, too. They are the only mammals that can fly.
So, what do mammals eat? Cows, horses, pandas, beavers are plant eaters. Other mammals
such as whales, dolphins, tigers, and lions are meat eaters. Human beings
and some bears eat both plants and meat.  Some
mammals including ant-eaters and pangolins eat insects.
<Fun facts about mammals>
- Only mammals have hair. All mammals have hair at some time in their lives.
Dolphins and whales lack body hair. So they have
a thick layer of fat that help them
stay warm. Other mammals with little hair such as elephants live in
warm areas.
- Mammals have larger brains than other animals. Some mammals, including
human beings, chimpanzees, and dolphins are highly intelligent.
- Most mammals give their babies more protection and training than other animals.
- Only mammals sweat. Primates have sweat glands all over their
bodies. But cats, dogs and mice have them on their feet. |
