Deer or true deer are hoofed ruminant mammals forming the family Cervidae. The two main groups of deer are the Cervinae, including the muntjac, the elk (wapiti), the red deer, the fallow deer, and the chital; and the Capreolinae, including the reindeer (caribou), the roe deer, the mule deer, and the moose.

The deer (family Cervidae) comprises 43 species of hoofed ruminants in the order Artiodactyla.

Horses are ungulates mammals with hooves. They also have long tails, short hair, muscular torsos, long thick necks and elongated heads. Due to domestication, they are found all over the world. Horses have lived on Earth for more than 50 million years, according the American Museum of Natural History.

Zebras are classified in the genus Equus (known as equines) along with horses and asses. These three groups are the only living members of the family Equidae.A 2013 phylogenetic study found that the plains zebra is more closely related to Grevy's zebras than mountain zebras.
