This family belongs to the order of even-toed ungulates (Cetartiodactyla) and contains the dromedary camels, Bactrian camels, wild Bactrian camels, llamas, alpacas, vicuñas, and guanacos. The llama and alpaca are domesticated forms of the guanaco and vicuña, respectively, and all four of these are found in South America. The dromedary and camel live in Africa and Asia and are well adapted to living in dry environment with little to no water.
Most people will immediately think of the humps on the back when hearing the word "camel". The dromedary and the Bactrian camels have respectively one and two humps, something the other members of this family lack. The hump is used to store fat, which the animal can break down to meet its water and energy needs when times are harsh.
