The camel can go without water for a long time. Some people think it stores water in its hump. This is not true. It stores food in its hump. The camel's body changes the food into fat. Then the fat is stored in the hump. A camel cannot store the fat all over its body. Fat all over an animal's body keeps the animal warm. Camels live in the desert. They do not want to be warm during theday.
