Red-shanked douc

The red-shanked douc, Pygathrix nemaeus, is an arboreal and diurnal Old World monkey of the subfamily Colobinae, known for its bright colours and for differences in body size between the sexes. It is native to Indochina, in Vietnam and southern Laos and possibly northeastern Cambodia east of the Mekong, and it is the only douc that lives in all three countries. Laos is believed to hold the largest population, and the Sơn Trà Nature Reserve in central Vietnam holds the largest Vietnamese one, about 700 to 1,300 animals. It lives in fission-fusion societies with an average band of 18 and is highly folivorous, eating buds and young leaves most, with figs eaten all year. The IUCN has declared it critically endangered, with hunting, habitat loss and the pet trade as the main threats.
