A cloven hoof, cleft hoof, divided hoof, or split hoof is a hoof split into two toes. Members of the mammalian order Artiodactyla that possess this type of hoof include cattle, deer, pigs, antelopes, gazelles, goats, and sheep.[1]
The two digits of cloven-hooved animals are homologous to the third and fourth fingers of the hand. They are called claws and are named for their relative location on the foot: the outer, or lateral, claw and the inner, or medial claw. The space between the two claws is called the interdigital cleft; the area of skin is called the interdigital skin. The hard outer covering of the hoof is called the hoof wall or horn. It is a hard surface, similar to the human fingernail.[2]
The almost finger-like dexterity available to cloven-hooved mammals such as mountain goats and wild sheep combined with a hard outer shell and soft and flexible inner pads provides excellent traction in their precarious habitats.[3][4][5]
