Vulnerable (IUCN 3.1)|Vulnerable
The pygmy slow loris (Nycticebus pygmaeus) is a species of slow loris found east of the Mekong River in Vietnam, Laos, eastern Cambodia, and China. It occurs in a variety of forest habitats, including tropical dry forests, semi-evergreen, and evergreen forests. The animal is nocturnal and arboreal, crawling along branches using slow movements in search of prey. It lives together in small groups usually with one or two offspring. An adult can grow to around 19 to 23 cm (7.5 to 9.1 in) long and has a very short tail. It weighs about 450 g (1.0 lb). Its diet consists of fruits, insects, small fauna, tree sap, and floral nectar. The animal has a toxic bite. The pygmy slow loris mates once every 12–18 months and has one or two offspring after an average gestation period of six months. Females reach sexual maturity by 16 months, while males reach maturity by about 18 months. The pygmy slow loris is seasonally fertile during the months of July and August.
The habitat of the pygmy slow loris in Vietnam was greatly reduced due to extensive burning, clearing, and defoliating of forests during the Vietnam War. Extensive hunting for traditional medicines is currently putting severe pressure on Cambodian populations. The pygmy slow loris is seriously threatened by hunting, trade, and habitat destruction; consequently, it is listed in Appendix II of the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), and in 2006 the International Union for Conservation of Nature (IUCN) classified it as "Vulnerable".
