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.
关于骆驼驼峰的一个常见迷思是它储存水。虽然骆驼确实可以在没有水的情况下生存超过一个礼拜，牠们并不在驼峰里储存水。牠们的驼峰反而主要是由脂肪组成。骆驼驼峰里可储存多达八十磅的脂肪。当骆驼长时间缺乏食物，例如在旱季时，这些脂肪就会转化为能量。这让骆驼可以在不进食的状况下生存数个月。当骆驼耗尽其脂肪供应时，驼峰就会缩小。
