Camels - the Cars of the Desert

Camels could be included in the mammal section, but they are such an important part of the desert we devoted a whole page to them! Camels are the cars of the desert. Without them, people would have great difficulty crossing the hot terrain.

There are two types of camels: bactrian and dromedary. The main difference between the two is the number of humps. Dromedaries have one hump, and bactrian have two. Both kinds are used by people, but only bactrians are found in the wild.

Camels are great for transportation because they use very little water. Camels can withstand very high temperatures without sweating. They also store fat in their humps for food. If a bactrian camel travels a long distance without eating, its hump will actually get smaller!
