The world of Mammals
Mammals in vlude animald such as the Whale, the Kangaroo, and you and me! We all have fur, we are warm blooded, and we feed new babies our milk.
Mammal babies :
Most mammal females give birth to live babies, rather than laying eggs. The baby grows inside the mother's body until it is born.
Feeding babies :
All female mammals produce milk from their bodies that they feed to their babies; this feeding is called suckling. The milk is rich and helps the babies grow.
The skeleton :
Mammals may look very different, but stripped back to the bone, we all have the basic bony skeleton. Scientists call us vertebrates - animals with a back bone.
Hairy beasts :
All mammals are hairy - some are much hairier than others - and most have hair, often called Fur, all over their bodies. They are hairy to keep them warm.
Eg : Elephant may know look hairy but it does have hair on its body.
Warm blood :
Mammals are warm blooded, which mrans they can warm up and cool down their bodies to keep their temperature level. An elephant in thr hot jungle is the same temperature as a polar bear in the snow.
The polar bears can live in chilly Arctic regions because they are warm blooded and have thick fur.
The polar bear has thick fur all over its body.
How many mammal families are there?
There are about 4,500 different types of mammals in the world.
Getting around :
Mammals are many different shapes that suit their lifestyles.
Cats :
Some mammals, such as cat, have long legs to run with.
Bats :
The bat is the only mammals that can fly - it has wings.
Dolphins :
Sea mammals have flippers and strong tails to swim with.
Moles :
The mole has feet like spades, which are useful for burrowing.
The odd one out :
It is usually true that animals give birth to live babies, but there are a few species, including this duck - billed platypus, that lay eggs. Platypus eggs are soft and the size of marbles.
