Deserts are dry. Deserts are extreme. True deserts get less than 6 inches of rain per year. There are also semideserts, which are desert like, but get more rain (up to 16 inches per year). True deserts have very few plants. Semidesert habitats have enough rainfall to support more plant and animal life.
Deserts (especially true deserts) are not easy places for animals to live. Animals who live in them often have special features that help them survive.
Some famous animals of the desert
Camels are often the first animal that comes to mind when thinking of a desert habitat. Camels have many characteristics that help them survive in the harshest and driest of the world's deserts.
Rattlesnakes - Some species of Rattlesnakes, like the sidewinder rattlesnake, make their home in the desert. These snakes often bury themselves in the sand or hide in animal burrows during the day, and come out to hunt lizards and small mammals at night.
