When many people all over the world think of Egypt, they think of the Pyramids with a graceful caravan of camels passing by them. It’s easy to imagine the caravans of the traders heading into the desert. With no food or water needed for the beasts of burden, we fancy that the journey was made easier. It is a romantic dream of many people to view such a caravan. The truth is, by far, stranger than the myths that have grown up around the camel, the beast of burden which helped spread wealth around the ancient world.
One of the most enduring and misunderstood myths about the camel is it's ability to go days without water. Myth tells us that the camel stores water in its hump. The truth is the hump, or humps in the case of the Bactrian camel, are a fatty deposit that provides energy when food is scarce.
When a camels energy reserves become low from lack of food, the hump shrinks and becomes soft and will actually flop over to one side. The resilient nature of the animal can be seen in the rapid return of the hump to its normal firm upright self after just a few days of good grazing.
The camel stores water in its blood stream, an interesting physiological process. The camel has developed, over the centuries, a unique water saving biology. Capable of losing forty percent of its body's weight before becoming distressed, it is able to go five to seven days before having to drink. The amount it drinks when water is available would cause severe problems in most animals, up to 21 gallons in about 10 minutes. If moisture-laden forage is available, a camel will not need as much water. The water it drinks can be too salty or brackish for other animals.
The camel's mouth, stomach, and teeth have all developed to allow it to eat plants that are not palatable to other desert animals. The camel's mouth is tough and rubbery so that thorns and branches won't damage it. The thirty-four sharp teeth allow it to bite off tough bites of almost anything, and when forage is short a camel can subsist on meats, skin and bones. Camels are ruminants, similar to cows, with three stomachs. They don't chew their food. They eat by swallowing their food whole and allowing it to be partially digested by the stomachs before being chewed as a cud later.
