Animals and plants live in diverse climatic conditions of deserts (hot and cold), jungles, oceans, etc. Arctic Fox. Only a few types of plants and animals are able to survive here. Deserts cover about one fifth of the Earth's land surface. Most of the precipitation in the Great Basin Desert falls as snow. Extreme aridity renders some deserts virtually devoid of plants; however, this barrenness is believed to be due in part to the effects of human disturbance, such as heavy grazing of cattle, on an already stressed environment. Prior to then both species had been known as the desert tortoise. In the heat of the day many diurnal animals will rest in the shade of a plant or under a rock. Cold-adapted mammals of the Antarctic region include elephant seals and several species of birds, including many types of penguins. Australia has a small feral dromedary population made up of the descendants of animals introduced to the country by humans. Plants in this type of environment must be hardy, and animals are usually small to reduce moisture loss. The Gila monster is a lizard found in a range of dry habitats throughout the southwestern United States and Northern Mexico.

Many camel spiders can be identified by their large, powerful mouth parts. The truth about a cold desert is that, even though temperatures may not be excessively hot, dehydrating conditions make survival difficult. Extreme Temperatures The temperatures in the desert range quite a bit, from getting cold enough to snow and to freeze water in the winter, to hot enough to fry an egg on a rock on a summer day. As one of the biggest and strongest vultures, the lappet-faced vulture will prevent other vultures from feeding on carrion it has found.

Cold desert biome plants have adapted to existence in high elevations and may withstand cooler winters than individuals in warm desert biomes. They represent the most extreme result of the progressive cooling and consequent aridification of global climates during the Cenozoic Era (65.5 million years ago to the present), which also led to the development of savannas and scrublands in the less arid regions near the tropical and temperate margins of the developing deserts. The ability to stay hydrated helps desert plants grow healthy in extremely hot or cold environments. There are two species of mulgara: the brush-tailed mulgara and the crest-tailed mulgara.

The greater roadrunner is one of two species of roadrunner, the other being the lesser roadrunner (Geococcyx velox), which is found in Mexico and Central America. Polar bears live in one of the planets coldest environments and depend on a thick coat of insulated fur, which covers a warming layer of fat. The deathstalker inhabits desert and scrubland habitat in North Africa and Western Asia. About one third of the worlds land surface is covered by deserts, and while many of them are indeed hot, some are bitterly cold. Desert plants have padded leaves that store water during the drought.
