MAMMALS
Mammals are warm-blooded (endothermic) vertebrates that have hair or fur and have mammary glands that produce milk to nourish their young. The astonishing diversity among mammals ranges from tiny field mice the size of a thimble to the massive blue whale. Mammals occupy all continents and can live on land, below ground, in trees, in the air and in fresh or salt water. Humans are members of the mammal family.
