Silvery lutung

Mammals

The silvery lutung (Trachypithecus cristatus), also known as the silvered leaf monkey or the silvery langur, is an Old World monkey and the type species of its species group. It is arboreal and lives in coastal, mangrove and riverine forests in Sumatra, Borneo and Java, parts of the southwestern Malay Peninsula, the Natuna Islands and other nearby islands. The grey-tipped dark brown or black fur gives it a uniform silvery look, and the only pale marking is a whitish patch on the groin of females. Females weigh about 5.7 kilograms and males about 6.6 kilograms. It is a specialist folivore, taking a higher share of leaves than any other colobine monkey, and a large three-chambered stomach with a long, pouched intestine ferments the food. Groups of roughly 9 to 40 animals hold one adult male and many females and are diurnal and rarely leave the trees. The IUCN classifies it as vulnerable and it is in CITES Appendix II, with logging, oil palm plantations, hunting for meat and the pet trade as the threats. It is unusually susceptible to human diseases and has been widely used in medical research.
