A camel is an even-toed ungulate within the genus Camelus, bearing distinctive fatty deposits known as humps on its back. There are two species of camel: Dromedary, or one-humped camels, which are native to Arabia and other parts of the Middle East, and Bactrian, or two-humped camels, which live in Central Asia. Both species have been domesticated; they provide milk and meat, and are working animals.
The term camel is derived via Latin and Greek from Hebrew or Phoenician gāmāl, possibly from a verb root meaning 'to bear/carry' (related to Arabic jamala).
Camel is also used more broadly to describe any of the six camel-like creatures in the family camelidae: the two true camels, and the four South American camelids: the llama, alpaca, guanaco, and vicuña.
The average life expectancy of a camel is 40 to 50 years. A fully grown adult camel stands 1.85 m (6 ft 1 in) at the shoulder and 2.15 m (7 ft 1 in)[clarification needed] at the hump. The hump rises about 75 cm (30 in) out of its body. Camels can run at up to 65 km/h (40 mph) in short bursts and sustain speeds of up to 40 km/h (25 mph).
