mam•mal

(ˈmæm əl)

n.

any warm-blooded vertebrate of the class Mammalia, characterized by a covering of hair on some or most of the body, a four-chambered heart, and nourishment of the newborn with milk from maternal mammary glands.

[1820–30; as singular of New Latin Mammalia, neuter pl. of Late Latin mammālis of the breast. See mamma², -al¹]

mam·mal

(măm′əl)

Any of various warm-blooded vertebrate animals whose young feed on milk that is produced by the mother's mammary glands. Unlike other vertebrates, mammals have a diaphragm that separates the heart and lungs from the other internal organs, red blood cells that lack a nucleus, and usually hair or fur. All mammals but the monotremes bear live young. Dogs, mice, whales, and humans are mammals.
