Diurnal and semi-terrestrial. They are good swimmers and will jump into water from nearby trees. They live in multi-male / multi female groups of 10 to 100 individuals.

IUCN Red List Status

Least Concern

Population trend

Decreasing

Threats

Across much of the species' range, the major threat is hunting. In mainland Sountheast Asia, females are taken into breeding facilities and males are exported internationally for use in laboratory research. Habitat loss is a localised threat but this species is able to adapt to many different environments.

Penampilan

Tubuh bulu bervariasi dari abu-abu sampai merah, dengan bagian bawah berwarna lebih muda. Para kera sering memiliki lambang menunjuk terlihat pada kepala mana rambut tumbuh mundur. Wajah mereka merah muda. Jantan memiliki bulu pipi (cambang) dan kumis; Betina memiliki jenggot. Juga dikenal sebagai 'monyet pemakan kepiting' (crab eating macaque).

Ancaman

Di banyak rentang spesies ini, ancaman utama adalah berburu. Di Asia Tenggara, betina dibawa ke fasilitas pembibitan dan jantan sering diekspor internasional untuk digunakan dalam penelitian laboratorium. Hilangnya habitat merupakan ancaman lokal tetapi spesies ini mampu beradaptasi dengan lingkungan yang berbeda.
