Both of the old world and new world camels belong to the subfamily Camelinae of the family Camelidae in the suborder Tylopoda of the order Artiodactyla. Camels are even- toed ungulates but differ from most others of their order in having soft, padded feet. They are generally referred to as special ruminants or occasionally as pseudoruminants because of their ruminating habits. Camels do not belong to the same suborder as the other major meat and milk producing domestic herbivores. It is now customary to place old world camels in genus Camelus and new world or South American camels in genus.
