Plant life in the Sahara includes about 2,800 vascular plant species, with a quarter of these being endemic to the region. The central Sahara alone harbors over 500 species of plants. These include acacia trees, succulents, Saharan cypress, grasses, Laperrine’s olive tree, date palms, tamarisk, spiny shrubs, and desert thyme. These plants have adapted by growing shorter to avoid water loss through strong winds, storing water in their thick stems, developing long roots to find surface moisture, and having small, thick leaves to reduce water loss through evapotranspiration.

Similarly, the fauna of the Sahara has adapted remarkably to the desert conditions. The desert is home to about 100 reptilian species, 90 avian species, 70 mammalian species, and various other animals. Notable species include desert foxes, addax antelopes, gazelles, Saharan cheetahs, African wild dogs, hyrax, deathstalker scorpions, Saharan silver ants, Dromedary camels, goats, sand vipers, monitor lizards, and desert crocodiles. Many of these animals have adapted to the extreme heat and dryness, with some being nocturnal to avoid the daytime heat and others capable of surviving long periods without water.

The adaptations of plants and animals in the Sahara are a testament to the resilience of life in one of the most extreme environments on Earth.
