- Are in the class Mammalia within the subphylum Vertebrata.
- Are warm-blooded. They have the ability to maintain their body temperature by internal means. The technical word for this is endothermy. Birds are the only other group of animals in the world that can do this.
- Feed their babies milk.
- Have hair. This unique body covering is made of keratin and grows from special cells located in the skin. Some mammals are hairier than others. Marine mammals such as whales may be virtually hairless.
- Have a four-chambered heart. This is the most advanced kind of heart. It keeps the arterial (oxygenated) and venous (oxygen-depleted) blood completely separate.
- Have live birth. The monotremes (platypus and echidnas) are exceptions in that they lay eggs. In marsupials, such as the opossum, the young are born in a very primitive state and then finish their development in an external pouch.
- Have very specialized and diversified teeth. Again, there are some exceptions (monotremes, baleen whales, e.g.), but the mammals have carried development of teeth farther than any other group of animals.
- Have a diaphragm. The diaphragm is the special muscle located below the lungs that draws air into the lungs. This increases the efficiency of breathing. No other type of animal has this muscle
DID YOU KNOW?
Black-tailed prairie dogs, named for their black-tipped tails and dog-like "bark," once lived throughout the Great Plains in "towns" that extended for miles and contained hundreds of thousands of individuals.
