Mammals (Mammalia) are a class of vertebrate homeothermic amniotes (of "warm blood") that possess milk-producing mammary glands with which they feed the young. Most are viviparous (with the notable exception of the monotrematas: platypus and echidnas). A clear example of a mammal is man and his best friend, the dog.
