The deer family, also called hoofed ruminant mammals, includes animals with bony, full antlers. Antlers are a bony formation that grows from the frontal bone of the cerebrum (a paired process) on the head of male deer (the exception is the reindeer, in which females also grow antlers). Antlers are shed for the winter and regrown every year and act as a weapon when bulls (male deer) are in need to defend themselves and fight for females during the mating season.
Representatives of deer include tundra reindeer, red deer, roe deer, Eurasian moose, European fallow deer, sika deer, white-tailed deer, and southern red muntjac.
