So the longer the camel goes without eating, the smaller its hump gets. The size of a camel's hump helps determine a camel's health, food sources, and overall well-being. These humps, or reserves of fat, are the reason why camels can go for days without water and food. Camels are the only animals with humps. Camels can produce up to 600 liters of milk a year.
Camels can close their nostrils.
Camels eat just about anything. When camels are really hungry and there is no food around, they won't think twice about gobbling up people's tents, sandals, or blankets. In some countries camels are a source of entertainment. For example, camel fighting attracts audiences of all ages in several countries around the world. Well not quite.
