Some animals live in the desert because they are conditioned to live there. They don't need much water, they don't have dark, thick fur and they can deal with the heat and lack of water because of these features.
Most deserts are warmer during the day then they are at night, and the difference in temperature is quite drastic. The average daytime temperature is 100°F, while at night the average temperature is 25°F. Normally, moisture in the air retains heat and helps regulate temperature. Due to the fact that there is very little moisture in the air, there is nothing to retain the heat created during the day by the sun. As a result, when the sun sets, the heat escapes and the temperature drops.

The desert is a large, hot biome with little life, consisting of only plants and animals that don't need much water to live, and are adapted to live there.

The Barrel cactus can be easily distinguished from other cacti
because of it cylinder-shaped body. The cactus usually reaches from around five to eleven feet tall, and at that height it is one of the largest cacti in the North American deserts. This cactus is really a man-sized (or bigger) cylinder with numerous parallel ridges that run down the sides. These ridges are topped with dangerously sharp 3-4 inch spines.
The brittlebush is a common plant of the Mojave and Sonoron deserts. It is a small deciduous shrub which grows as a low, roundish mound 2 to 5 feet high. They are about 1 to 4 inches long. The hairs form a blanket over the leaves and act an insulating layer against the heat and cold. They also trap any moisture that is in the air, and reduce the amount of water lost to dry air.
The unusual Joshua Tree grows in the protective setting of the Joshua Tree National Park in California and in the Joshua Forest Parkway in western Arizona. The Joshua Tree is the largest of the yuccas and grows only in the Mojave Desert. The Joshua Tree's height varies from 15 to 40 feet and has a diameter of 1 to 3 feet. The Joshua tree has a lifespan of about 200 years. The growing joshua trees are pretty much similar to palm trees.
From a distance the jumping cholla, or teddy bear cholla, looks like a fuzzy, soft plant with many short, fuzzy branches looking like teddybear arms, growing from the top. As you get closer you realize that the cuddly looking plant is completely covered with silvery spines. If you are unlucky enough to touch the spines, you will find yourself painfully stuck to a spiny segment that seems to have "jumped" off the plant. Segments will also "jump" when stepped on and attach themselves to your leg.

Food Chain for the Desert
Overview of the Desert
Deserto (nocturnal)
Burrows in sand to keep cool...
"Armored" palms to rip cactus.
Many desert animals tend to be nocturnal, sleeping during the day and coming out at night when the temperatures are more tolerable.
There are some deserts in Antarctica that are known as cold deserts. They are considered deserts because of the small amount of vegetation that grows there.
