DESERT PLANTS
Most desert species have found remarkable ways to survive by evading drought. Desert succulents, such as cacti or rock plants (Lithops) for example, survive dry spells by accumulating moisture in their fleshy tissues. They have an extensive system of shallow roots to capture soil water only a few hours after it has rained. Additionally, many cacti and other stem-succulent plants of hot deserts present columnar growth, with leafless, vertically-erect, green trunks that maximize light interception during the early and late hours of the day, but avoid the midday sun, when excessive heat may damage plant tissues.
One of the most effective drought-survival adaptations for many species is the evolution of an ephemeral life-cycle. An ephemeral life cycle is characterized by a short life and the capacity to leave behind very hardy forms of propagation. This ability is found not only in plants but also in many invertebrates. Desert ephemerals are amazingly rapid growers capable of reproducing at a remarkably high rate during good seasons.
DESERT ANIMALS
Birds and large mammals can escape critical dry spells by migrating along the desert plains or up into the mountains. Smaller animals cannot migrate but regulate their environment by seeking out cool or shady places. In addition to flying to other habitats during the dry season, birds can reduce heat by soaring. Many rodents, invertebrates, and snakes avoid heat by spending the day in caves and burrows searching out food during the night. Animals active in the day reduce their activities by resting in the shade during the hotter hours.

desert holds a place in the world as one of the most grueling terrains in existence. Although it can be a very void place, there is no shortage of desert animals and plants —they are simply better adapted to the environment. Animals and plants range from large camels that have been utilized for transportation for centuries to trees that have learned to survive on very little water. For desert plants and animals, information is abundant even if water is scarce.
Bilby or Bandicoot
The bilby—or the rabbit-eared bandicoot—of the deserts of Australia is considered to be an endangered species since they are preyed upon by animals and people alike. All species being nocturnal, they go underground during the day and ferret food at night. Insects, snails and mice, as well as fruit and underground bulbs serve as food for these little marsupials.
The Arabian Camel
The dromedary, more popularly known as the Arabian camel, can be found in the Middle East, Africa, as well as, India and Pakistan. Amazingly, these single hump-backed animals store fats in their humps—making them go for 3 to 4 days with no water and food. Their diet includes grass, dates, oats and wheat.
