A common myth about the camel’s hump is that it stores water. While it’s true that camels can go for more than a week without water, they don’t store water in their humps. Instead, their humps are mostly made up of fat. As much as 80 pounds of fat can be stored in a camel’s hump. This fat is turned into energy when a camel goes without food for a long time, such as during the dry seasons. This allows a camel to survive several months without eating. When a camel uses up its supply of fat, the hump will shrink.
關於駱駝駝峰的一個常見迷思是它儲存水。雖然駱駝確實可以在沒有水的情況下生存超過一個禮拜，牠們並不在駝峰裡儲存水。牠們的駝峰反而主要是由脂肪組成。駱駝駝峰裡可儲存多達八十磅的脂肪。當駱駝長時間缺乏食物，例如在旱季時，這些脂肪就會轉化為能量。這讓駱駝可以在不進食的狀況下生存數個月。當駱駝耗盡其脂肪供應時，駝峰就會縮小。
