Artiodactyla are known as the even toed animals.
Artiodactyls are sometimes called cloven hooved, that is they have two toes.
A single living species, the pronghorn, sums up the family Antilocapridae. This animal is sometimes considered a living fossil. It shows many primitive traits. Perhaps the most obvious primitive attribute is in that pronghorns shed their horns yearly just like a deer. It is the only living horned animal that does this.
