Why do camels have 1 or 2 humps?

Answer 1

A camel's (not cammal, by the way) hump is a giant mound of fat, actually. In a healthy, well-fed camel, the hump can weigh as much as 80 pounds! Human beings and most animals store their fat mixed in with muscle tissue or in a layer right beneath the skin. Camels are the only animals with a hump. The hump allows a camel to survive an extremely long time (up to two weeks) without food if need be. Because camels typically live in the desert, where food can be scarce for long stretches, this is important.

Answer 2

Why is kinda hard to answer, as no one knows exactly how an animal ends up looking like it does.

But for the camel, it works. The hump, or humps is basically fatty tissue, which the camel can use as emergency rations of food and water. For an animal that livens ina desert, where food and water can be real rare, that's a quite useful trick

Answer 3

Only Bactrian Camels have two humps, and dromedaries have one but I know that they store fat (not water) in their humps

Answer 4

to store fat
