Why do camels have humps?
Well, it’s not to store water. The humps are there to store fat. Similar to how most animals store fat around their bellies, camels store it in their one or two humps on their backs. When camels cannot get
to food they live off of the stored fat in their humps. As this fat is consumed by the camel’s body, the hump shrinks, and in the case of a two-humped Bactrian camel the tops of the humps flop over to one side. The humps will resume their full shape once a camel eats again.
