General Facts about Mammals
Mammals are one of the 6 main classes of animals. Animal classes are groups of animals that scientists consider to be alike in some important ways. Mammals are the animal class that people belong to. There are only about 4,000 kinds of mammals. This sounds like a lot, but when you consider there are 21,000 kinds of fish and a whopping 800,000 kinds of insects you’ll realize mammals are a pretty small class! Mammals are warm blooded. All mammals have fur or hair. Mammals are the only animals with true hair. Hair are dead cords of a substance called keratin which is also what our fingernails are made from. The most important part is that hair is dead. All the mammal's drink mother's milk. |
