Asian Monkeys: Macaques, Langurs and Snow-Country Primates

Asia’s monkeys include the most northerly primates on Earth and some of the most specialised leaf eaters in the order. They also live closer to dense human populations than monkeys anywhere else, which makes the continent a case study in coexistence and conflict.

Macaques: The Great Generalists

Macaques range from Afghanistan to Japan and from Sri Lanka to Sulawesi. Rhesus and long-tailed macaques flourish in cities, temples and farmland, Japanese macaques survive snowbound winters, Tibetan macaques handle high-altitude cold, and Sulawesi’s crested macaques are island endemics. Their behavioural flexibility and tool traditions are covered in smartest monkey species. Our macaque profiles describe individual species in more detail.

Japanese Macaques

The snow monkeys of Honshu live further north than any other non-human primate, enduring months of freezing weather with thick coats, group huddling and famously by bathing in volcanic hot springs. Local troops maintain distinct traditions, including food washing and stone handling, passed between generations.

Langurs and Leaf Monkeys

Grey langurs are the familiar temple monkeys of the Indian subcontinent, while a large group of surilis and leaf monkeys occupies Southeast Asian forest. All rely on complex, fermenting stomachs to digest mature leaves, an adaptation described in monkey adaptations. Several species, including the Cat Ba langur of Vietnam, are down to tiny populations.

Snub-Nosed Monkeys

Found in China, Myanmar and Vietnam, snub-nosed monkeys live in montane forest where snow is normal in winter. They survive on lichen, bark and buds during the lean months and form large multi-level societies. They are also among the most threatened primates in Asia.

The Proboscis Monkey

Endemic to Borneo, the proboscis monkey is Asia’s largest monkey and one of its strangest, with the male’s pendulous nose amplifying his calls. It lives in riverine and mangrove forest, swims strongly between patches, and specialises in unripe fruit and leaves. Habitat details in monkey habitats explained.

Living Alongside People

Temple and city macaques enjoy abundant food and low predation, and the result is high density, bold behaviour and frequent conflict over crops and property. Effective management focuses on securing food waste rather than removing animals, and the wider issues are discussed in monkey conservation.

Conservation

Deforestation for oil palm, timber and agriculture is the dominant threat, compounded by hunting and the pet trade. Island endemics are especially exposed because they have nowhere to retreat. See endangered monkey species.

Frequently Asked Questions

What is the most common monkey in Asia?

The macaques, particularly rhesus and long-tailed macaques, which thrive in cities, temples and farmland as well as forest.

Which monkey lives in snow?

The Japanese macaque, or snow monkey, which survives northern Honshu winters with dense coats, huddling and hot spring bathing.

What is the largest monkey in Asia?

The proboscis monkey of Borneo, with males reaching about 20 to 24 kilograms.

Why do Asian monkeys conflict with people so often?

Because their ranges overlap heavily with dense human populations, and easily available food waste and crops support unusually high monkey densities.
