Camels can travel great distances across hot, dry deserts with little food or water. They walk easily on soft sand where trucks would get stuck, and carry people and heavy loads to places that have no roads.
Camels also serve the people of the desert in many other ways.
A camel carries a built-in food supply on its back in the form of a hump. The hump is a large lump of fat that provides energy for the animal if food is scarce. These hybrid camels had one extra-long hump and were larger and stronger than either parent. Camels have been domesticated by people for thousands of years. Arabian camels may once have lived wild in Arabia, but none are wild today.
