Camel among these animals is not a lamoid. A camel is an even-toed ungulate in the genus camelus, bearing distinctive fatty deposits known as "humps" on its back. Camels do not directly store water in their humps as was once commonly believed.
The humps are actually reservoirs of fatty tissue: concentrating body fat in their humps minimizes the insulating effect fat would have if distributed over the rest of their bodies, helping camels survive in hot climates. In hot and dry environments, within 8 to 10 days only the dromedary camels might consume water which during this period the third of their body's weight may be reduced due to the dehydration.
