A camel is an even-toed ungulate in the genus Camelus, bearing distinctive fatty deposits known as "humps" on its back. The three surviving species of camel are the dromedary , or one-humped camel (C. dromedarius ), which inhabits the Middle East and the Horn of Africa; the Bactrian , or two-humped camel (C. bactrianus ), which inhabits
Central Asia; and the critically endangered wild Bactrian camel (C. ferus ) that has limited populations in remote areas of northwest China and
Mongolia . Bactrian camels take their name from the historical Bactria region of Central Asia. Additionally one other species of camel [3] in the separate genus Camelops , C. hesternus
[4] lived in western North America and became extinct when humans entered the continent at the end of the
Pleistocene. Both the dromedary and the Bactrian camels have been domesticated; they provide milk , meat,
hair for textiles or goods such as felted pouches, and are working animals with tasks ranging from human transport to bearing loads.
