Detailed explanation-1: -Nocturnal desert animals keep cool by being active at night, whereas some other desert animals get away from the sun’s heat by digging underground burrows. Other common adaptations seen in desert animals include big ears, light-colored coats, humps to store fat, and adaptations that help conserve water.

Detailed explanation-2: -An organism’s water demand increases as temperature rises. So, desert animals have developed many adaptive strategies like they usually come out at night when the desert is cooler for coping with temperature extremes and limited water. They are called nocturnal animals.

Detailed explanation-3: -Diurnal animals protect themselves from the heat by spending most of the day in whatever shade they can find.

Detailed explanation-4: -The primary strategy for dealing with high desert temperatures is avoidance-many mammals simply avoid the high daytime temperatures by being nocturnal or crepuscular (dusk-or dawn-active).

Detailed explanation-5: -They stay deep underground in burrows. There the sand is much cooler, and burrowing animals, like the antelope squirrel, the badger, the gopher, the coyote and the kit fox, sleep while you are playing on the dunes. At night, after the sun goes down and the sand cools off, the animals come out to hunt for food.
