Desert Animals • There are many animals in the desert. • They can survive by eating other animals or by eating plants that store water. • To protect them from the hot sun, they stay in the shade or in their shelter. • Animals may build their shelters inside plants. • Some animals sleep during the day and are active at night. • Some animals have hard shells to protect them from losing much water. • More animals live in hot deserts than in cold deserts.
