2. What is a mammal?
Mammals are animals that use lungs to breathe air, produce milk, are warm-blooded, vertebrates and are covered in hair.

3. Vertebrates
Mammals are vertebrates, which means that they all have backbones (spines). 

4. All mammals have hair or fur
Sometimes it's long hair covers their entire body, other mammals have short hair or just a few strands.

5. Mammals under water
Even mammals that swim under the water (like whales and dolphins) have hair.
Its hard to find it! Whales have fine hair on the lips.

6. Mammals are warm blooded.
The temperature could be really cold or very hot, but mammals’ bodies are built to maintain just about the same temperature all the time.

7. Believe it or not!
Mammals are the animal class that people belong to.  

8. Bats
Yes a bat is a mammal, it has wings and it’s not a bird.

9. Mammal Babies: all drink Milk
Baby mammals are born different ways, but they all drink milk that comes from their mothers' bodies. Baby pigs, lions, dogs, dolphins, bats and elephants all drink milk!

10. Mammal mothers
The mammal mothers have to care for their young.

11. Teeth People have "milk teeth“, animals too.
Except anteaters, they don’t have teeth at all!

12. Special mammals (anteaters)
There are, however, a few mammals (like the duckbilled platypus and the spiny anteater) who lay eggs like a bird!
