Why does a camel have a hump?

The camel is called 'the ship of the desert' and there is a good reason for this. Just as a ship is constructed to deal with all the problems that arise from being in the water, so a cannel is built to live and travel and survive in the desert. Where other animals would die from lack for food and water, the camel can survive as it carries its food and water with it. For days before it starts on a journey, a camel does nothing but eat and drink. It eats so much that a hump of fat, weighing as much as 45 kg (100 1b), rises on its back. So, the camel's hump is a storage place for fat, which the camel's body will use during the journey. The camel also has flask-shaped bags which line the walls of its stomach, and this is where it stores water. With these provisions, a camel is able to travel several days between water holes without drinking.
