Camel's humps are made of fat. They can travel for long periods in the desert without food because their bodies use the fat in the humps as nourishment. However, camels are able to drink great amounts of water, which is stored in their stomachs.
The Bactrian, or two-humped, camel has shorter legs than the dromedary and is not able to move as swiftly at its fastest face. A few wild bands still roam the Gobi desert.
The dromedary or Arabian camel, one-humped camel, can be trained to carry heavy loads on long journeys. Adapted to life in the desert, the camel has horny pads on the knees, thigh joints, and the chest- the areas on which it rests- and long eyelashes, hair-covered ear openings, and slitlike nostrils for protection from sand and wind.
