The Cat Ba langur (Trachypithecus poliocephalus), also known as the golden-headed langur, is a critically endangered species of langur endemic to Cat Ba Island, Vietnam. It is among the rarest primates in the world, with a population estimated at fewer than 70 animals. It was considered a subspecies of Francois' langur until 1995, and the white-headed langur of China was formerly counted as its subspecies until 2007. The animal is blackish with a yellowish crown, cheeks and neck, a tail of about 85 centimetres against a body of about 50, and golden-orange babies whose fur changes colour from about the fourth month. It lives in moist tropical rain forest on steep limestone hills, in groups of about four to eighteen with one male and several females, and eats mainly leaves, which make up over 70 percent of the diet, along with shoots, flowers, bark and some fruit. Hunting for traditional medicine cut the population sharply between 1970 and 1986, and protection since 2000, including an expanded national park, has helped it recover from about 40 animals in 2003.
