The red-shanked douc can only be found in Cambodia, Laos, and Vietnam. These primates are an Old World (monkeys hailing from Asia or Africa) creature that dwells in the mid to upper levels of the forest canopy in mountainous to lowland terrains, semi-deciduous, primary, and secondary rainforests. Unfortunately, due to habitat destruction at the hands of urban and suburban developments, mining, agriculture, and dams; development of roads that divide their territory and cause the risk of vehicle strike (being hit with vehicles); hunting; and trapping, these primates are listed as Critically Endangered by the IUCN. Their numbers are also decreasing.
