Deer At Zoo Stock Photo

Deer singular and plural are the hoofed ruminant mammals forming the family Cervidae. The two main groups are the Cervinae, including the muntjac, the elk wapiti, the fallow deer, and the chital; and the Capreolinae, including the reindeer caribou, the roe deer, and the moose. Female reindeer, and male deer of all species except the Chinese water deer, grow and shed new antlers each year. In this they differ from permanently horned antelope, which are part of a different family Bovidae within the same order of even-toed ungulates Artiodactyla.
