from Latin mamma "breast"), a clade of endothermic amniotes distinguished from reptiles (including birds) by the possession of a neocortex (a region of the brain), hair, three middle ear bones, and mammary glands.
Females of all mammal species nurse their young with milk, secreted from the mammary glands.
The largest group of mammals, the placentals, have a placenta, which enables the feeding of the fetus during gestation.
