If you think the secret to a camels’ success in the desert lies in its humps,you are right. If you think those humps are flush with fresh water like gurgling water coolers, you are wrong. A camel’s humps are filled with fat-enough fat to supply the animal with energy and hydration for long hauls through the desert.
Camels can also adjust their body temperature to deal with the baking sun, and their brains have a sort of natural air-conditioning. But it’s really the humps that keep them going (plus the scant bit of moisture they get from nibbling on desert piants).
