What are mammals?

Mammals are a particular class of animal. What makes an animal a mammal are several things. First, they must have glands that give milk. This is to feed their babies. Second, they are warm-blooded. Third, all mammals have fur or hair. Humans are mammals and so are dogs, whales, elephants, and horses. Most mammals have teeth with the exception of the ant eater which doesn't have any teeth. 


Mammals live in all sorts of environments including the ocean, underground, and on land. Some mammals, bats for example, can even fly. 

Mammals have unique brains and are often very intelligent. Humans are the most intelligent. Other intelligent mammals include the dolphin, the elephant, the chimpanzee, and the pig. That's right, pigs are thought to be one of the smartest animals!
