A popular misconception is that the camel stores water in its hump. The humps actually contain fatty tissue which helps in surviving in the harsh desert climate. When this fat is metabolized, it acts as a source of energy and can yield 1 gm of water for every gram of fat, which is probably the reason for the misconception. Having adapted themselves to the hot desert climate, the camels can go without water for long periods. The only reason why they do not suffer dehydration is the oval shape of their red blood cells ensures smooth flow even after dehydration sets in due to lack of water. The cells are conditioned to remain stable even there is enough water. A camel can drink up to 100 to 150 litres of water at one go. These type of oval RBC’s are not found in any other mammals.
