Camelus

Camelus is a genus of even-toed ungulates, the camels, in the family Camelidae, comprising three living species, the dromedary, which makes up about 94 percent of the world camel population, the domestic Bactrian camel at about 6 percent, and the endangered wild Bactrian camel. Camels are distinguished by fatty humps on their backs that store energy rather than water, oval-shaped red blood cells and an ability to withstand extreme dehydration. Roughly 14 million camels existed as of 2010, with the largest concentration in the Horn of Africa; domesticated dromedaries range across West Asia, North Africa and South Asia, and more than a million feral camels live in Australia.
