The males of this family, and a few females, have ever growing horns. They are some of the worlds largest land animals and comprise much of the diets of many of the large carnivores of the world. Animals in the order Artiodactyla are known as the even toed animals.
Artiodactyls are sometimes called cloven hooved, that is they have two toes.
Artiodactyla skulls come in many shapes and forms. Those found in Old World pigs are large and massive with large upper canines that grow outwards and backwards forming tusks. The skull of the New World equivalent of a pig, the peccary, is small and more delicate. Its canines grow downward and meet with the lower canines to form precision scissors. Animals of the order Artiodactyla may have antlers or horns.
