Deer

A deer is a ruminant mammal belonging to the family Cervidae. A number of broadly similar animals from related families within the order Artiodactyla (even-toed ungulates) are often also called deer. Male deer, also called bucks, grow and shed new antlers each year, as opposed to antelope, which are in the same order and bear a superficial resemblance to deer physically, but are permanently-horned. Deer tend to travel in herds of nine and gather in low elevations.
