WHY DO CAMELS HAVE HUMPS?

Camels live in environments where food and water can be scarce, so they frequently go for long periods of time without eating or drinking. Camel humps are full of fat that they use for energy when they don’t have any food or water. Most animals have fat spread around their body, which is useful for animals like polar bears as they live in a really cold environment and the thick layer of fat around their body helps. With camels, all their fat is on their backs to avoid excess body heat. When all the fat has been used in a camel hump, it becomes floppy and hangs to one side.
