The family Cervidae are ruminant herbivores that belong to the order Artiodactyla (even-toed ungulates). They are foregut fermenters, meaning they regurgitate their food and chew it again. Probably the single most striking anatomical feature of the deer are their antlers, which are shed and regrown on an annual basis, with the exception of the Chinese water deer.
The family is divided into two subfamilies, the Cervinae, which includes the muntjac, fallow deer and the chital, and the Capreolinae, which includes the elk, reindeer (or caribou), the Western roe deer, and the moose.
