Deer are the ruminant mammals forming the family Cervidae. Species in the
family include the white-tailed
deer, mule
deer, elk, moose, red
deer, reindeer, fallow
deer, roe
deer, and chital. Male deer of all species and female reindeer grow and
shed new antlers each year. In this they differ from permanently horned animals, such as antelope,
which are in the same order as deer and may
bear a superficial resemblance to them. Source
