Those Camel Humps Are Used For More Than You Think
Camels store upwards of 30kg of nutrient-rich fat in their humps. During times of famine and drought, this fat is absorbed to nourish the camel. The humps actually go limp like a deflated balloon when the fat is depleted. (The humps also carry water, allowing camels to go across several miles of land with stored water to keep them hydrated until they reach some water.)
