Many are herbivores, but suids are omnivorous, and cetaceans are entirely carnivorous. Artiodactyls are also known by many extinct groups such as anoplotheres, cainotheriids, merycoidodonts, entelodonts, anthracotheres, basilosaurids, and palaeomerycids.

The order Artiodactyla consists of 349 extant species belonging to 132 genera. This does not include hybrid species or extinct prehistoric species. Modern molecular studies indicate that the 132 genera can be grouped into 23 families; these families are grouped into named suborders and many are further grouped into named clades, and some of these families are subdivided into named subfamilies.
