Desert Conditions

The two main adaptations that desert animals must make are how to deal with lack of water and how to deal with extremes in temperature. Many desert animals avoid the heat of the desert by simply staying out of it as much as possible.

Where do animals in the desert get their water from?

Since water is so scarce, most desert animals get their water from the food they eat: succulent plants, seeds, or the blood and body tissues of their prey.

How do desert animals prevent water from leaving their bodies?

Desert animals prevent water leaving their bodies in a number of different ways. Some, like kangaroo rats and lizards, live in burrows which do not get too hot or too cold and have more humid (damp) air inside. These animals stay in their burrows during the hot days and emerge at night to feed.

Other animals have bodies designed to save water. Scorpions and wolf spiders have a thick outer covering which reduces moisture loss. The kidneys of desert animals concentrate urine, so that they excrete less water.
