Encyclopedia Article for artiodactyl

any member of the mammalian order Artiodactyla, or even-toed ungulates, which includes the pigs (see table), peccaries, hippopotamuses, camels, chevrotains, deer, giraffes, pronghorn, antelopes, sheep (see table), goats (see table), and cattle (see beef and dairy tables). It is one of the larger mammal orders, containing about 150 species, a total that may be somewhat reduced with continuing revision of their classification. Many artiodactyls are well-known to man, and the order as a whole is of more economic and cultural benefit than any other group of mammals. The much larger order of rodents (Rodentia) affects man primarily in a negative way, by competing with him or impeding his economic and cultural progress
