The fauna of Asia includes animals living in the continent as well as the islands, seas, and oceans (Arctic Ocean, Pacific Ocean, Indian Ocean, Red Sea) surrounding it. The diverse habitats in Asia, from mountains to plateaus, plains to deserts, and variations in altitude, temperature, and rainfall make it home to various wildlife.
Fauna in Asia started from the Mesozoic Era or the Age of Reptiles (as alternately called) after the Laurasian supercontinent segregated from Gondwana.
Of the several zoogeographic regions encompassing Asia, the common ones include the European-Siberian area, where animals like the Siberian roe deer and moose are found. The Mediterranean Basin, a part of which is bordered by southwestern Asia, has around 13,000 species of plants and animals. The Middle-East desert region that includes the Arabian Desert has species like oryx, gazelles, spiny-tailed lizards, and sand cats. The Indochina area covering a significant part of Southeast Asia, including countries like Thailand, Myanmar, and Cambodia, has over 500 mammals, 1300 birds, 500 reptiles, and 300 amphibians.
The other regions in Asia, home to different animals, birds, reptiles, and insects, include Central Asia, West Asia, the Indian subcontinent, the Philippines, and Sunda Shelf.
