Camels are even-toed ungulates in the genus Camelus. The Dromedary or Arabian Camel has a single hump, and the Bactrian Camel has two humps. They are native to the dry and desert areas of western Asia and East Africa, and central and east Asia, respectively. The average life expectancy of a camel is 50 to 60 years. The term 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: Llama, Alpaca, Guanaco, and Vicuña.
