Camels are a large animal that is very well adapted for hot, dry weather. They can survive longer without water than any other animal. Camels have a big, fatty hump on their backs that stores food for times when they can't find enough to eat. They are taller than an adult man and are used to ride on or to pull carts.

There are two types of camel, the dromedary which has one hump, and the bactrian which has two. There are a lot more dromedaries than bactrians in the world.

Camels are related to llamas and alpacas.
