Animals of Asia
Asia is home to an extraordinary variety of animal species, spread across biomes ranging from tropical rainforest and mangrove coastlines to ice-cold high-alpine tundra. Here live both the largest populations of land animals on Earth and species teetering on the edge of extinction.
Biomes and animal habitats
The vast continent has five major biomes, each with its own fauna. The tropical rainforests of Borneo and Sumatra are among the most species-rich ecosystems on Earth. In these lowlands live the orangutan — our closest relative in Asia — the Sumatran tiger, the sun bear and hundreds of bird species. Deforestation for palm oil plantations has caused more than half of this rainforest to disappear over recent decades, which prompted the IUCN to classify the Sumatran tiger as Critically Endangered.
The Himalayas and the Tibetan Plateau form a world of their own. At altitudes of 3,000 to 5,500 metres the snow leopard thrives — one of the most elusive of the great cats. The yak, the takin and the bharal (Tibetan blue sheep) are adapted to thin air and sharp cold. The lower foothills provide habitat for the red panda, the one-horned rhinoceros and the Asian elephant.
To the north, the Siberian taiga stretches across more than 10 million km² — the largest contiguous forested area on Earth. Here live the Siberian tiger (Panthera tigris altaica), the brown bear, the wolf, the lynx and the wolverine. The taiga transitions into the Siberian steppe and semi-desert, habitat of the saiga antelope, the kulan (wild ass) and the snow leopard in the mountain ranges along the border with Mongolia.
The mangroves and coastal floodplains of South and Southeast Asia support unique species such as the Ganges river dolphin and the formidable saltwater crocodile (Crocodylus porosus), the largest living reptile on Earth. All these habitats face increasing pressure from urbanisation, agricultural expansion and climate change. The climate of Asia page explains how global warming is affecting the continent's ecosystems.
Overview table: threatened species of Asia
The table lists eight representative species with their primary habitat and the official IUCN Red List conservation status (version 2024). Categories: NT = Near Threatened, VU = Vulnerable, EN = Endangered, CR = Critically Endangered.
| Animal | Habitat | IUCN status |
|---|---|---|
| Bengal tiger (Panthera tigris tigris) | Mangrove forests (Sundarbans), Indian subcontinent | EN — Endangered |
| Bornean orangutan (Pongo pygmaeus) | Tropical lowland rainforest, Borneo | CR — Critically Endangered |
| Giant panda (Ailuropoda melanoleuca) | Mountain bamboo forests, central China (Sichuan, Shaanxi) | VU — Vulnerable |
| Snow leopard (Panthera uncia) | Rocky mountain areas, Himalayas and Central Asian ranges | VU — Vulnerable |
| Asian elephant (Elephas maximus) | Tropical and subtropical forest, South and Southeast Asia | EN — Endangered |
| Indian one-horned rhinoceros (Rhinoceros unicornis) | Alluvial grasslands, Nepal and Assam (India) | VU — Vulnerable |
| Komodo dragon (Varanus komodoensis) | Dry savanna and forest, Komodo islands (Indonesia) | EN — Endangered |
| Red panda (Ailurus fulgens) | Temperate mountain forests, eastern Himalayas and Yunnan | EN — Endangered |

The tiger: icon of Asian fauna
The tiger (Panthera tigris) is the largest wild-living cat in the world and simultaneously one of the most threatened mammals of Asia. At the start of the twentieth century, an estimated 100,000 tigers lived in the wild; by 2023 the IUCN counted fewer than 5,000 wild animals, spread across thirteen countries. The largest populations live in India (approximately 3,700 animals), followed by Russia, Nepal and Indonesia.
Poaching and habitat loss are the two main causes of decline. The international Project Tiger, launched in India in 1973, stands as one of the most successful conservation programmes: the number of tigers in India rose in fifty years from around 1,800 to nearly 3,700. Nevertheless, the survival of the Sumatran and Amur subspecies remains precarious.
Conservation and biodiversity treaties
Asian countries are largely signatories to the CITES convention (Convention on International Trade in Endangered Species), which prohibits trade in threatened animal species and their products. However, trade in tiger bones, rhino horn and elephant ivory remains a problem, fuelled by traditional medicine and demand on black markets.
National parks such as the Sundarbans (India/Bangladesh), Kaziranga (India), the Tangkoko reserve (Indonesia) and the Wolong reserve (China) play a key role. Internationally, WWF works with governments on corridor restoration: reconnecting fragmented forest areas so animals can move freely. For similar challenges on other continents, see the Africa page and the kids' page on animals by continent.
Endemic species and hotspots
Asia has several biodiversity hotspots — areas with an exceptionally high concentration of endemic species (species found nowhere else) that are simultaneously threatened by habitat loss. The Indo-Burma hotspot, stretching from Bangladesh to southern China, contains more than 1,300 bird species and over 430 mammal species. The Sundaland hotspot (Malay Peninsula, Borneo, Sumatra, Java) ranks as one of the five most species-rich places on Earth.
On the islands of the Philippines, more than 700 endemic bird species live, including the Philippine eagle (Pithecophaga jefferyi), one of the largest and most powerful raptors in the world. Japan is home to the Japanese macaque, the most northerly non-human primate, famous for bathing in hot springs in the Japanese Alps. This great biodiversity makes Asian habitats all the more valuable to protect, something that also comes up on the countries of Asia page in the context of national parks by country.
