The family Camelidae includes the camels, llamas, vicunas, and guanacos of the world. There are six species of camelids that differ in tremendously. Those found in northern Africa and the Middle East are large, have short course fur, and either one to two fatty humps for water conservation, an adaptation to life in the desert, while those found in South and Central America are medium sized with long soft fur, to aid in the cooler climates of their mountainous environments. All camelids have long necks and are herbivorous. 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 outward 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.
