Desert climate
Desert plants and animals have adapted to living in desert climates. Some animals can get by on less water. Some plants are able to store water. Some animals, like snakes, lizards and scorpions use poisonous venoms to kill for food. This saves valuable energy: they do not need to chase, fight or catch their prey. Many animals are nocturnal. They sleep in cool caves or burrows during the day and hunt at night. Plants likewise have adapted to saving water. Some have waterproof coverings that prevent the plant or seeds from drying out. Some, like the giant Saguaro cactus, store water. They have adapted so well that they can live for more than 150 years and can average over 40 ft tall. Many types have thorns and protective spines that keep animals from getting at their stores of water.
