There are many deserts in the world. Some of them are as big as a country. It is very hard to find water and food in deserts. The only animal that can walk across the desert is camel. It can live without(没有) drinking water and eating food for two weeks. It can carry many heavy things in the desert. People usually call the came! "The ship of the desert".
The camel is very big. It has one or two humps(驼峰) on the back, short ears and a long neck. The camel's humps are full of fat(脂肪). The fat can give the camel energy when it needs food. And its stomach has twelve small pockets. These pockets can hold(保存) many water. When the camel needs water, it can get water out of the pockets. The camel's food is grass and leaves. It also likes eating cactus(仙人掌). Its mouth is special, so it is not afraid of the thorns(刺) of cactus.
