Deer are members of the order Artiodactyle, which means that they have an even number of toes on each hoof. Deer are the only animals with antlers. Antlers are usually found only on male deer.
There are about 100 different types of deer in the world. Deer are native to every continent in the world except for Antarctica and Australia. Male deer are called bucks, bulls, stags or harts, while female deer are called does, cows or hinds. Young deer are called fawns or calves.
Deer have a great sense of hearing and smell. Deer also have a brown coat, which helps provide great camouflage in the woods.
