The black-crested Sumatran langur, Presbytis melalophos, is a species of Old World monkey in the family Cercopithecidae that is endemic to Sumatra, Indonesia, and several neighbouring islands. It is a forest-dwelling animal and is threatened by habitat loss: from 2000 to 2012 it lost an estimated 62 percent of its forest habitat. The black Sumatran langur, black-and-white langur, Sarawak surili, Raffles' banded langur and mitered langur were formerly considered subspecies of it. The animal eats both fruit and leaves, with fruit making up 50 to 60 percent of the diet and the rest mostly leaves, with seeds and flowers taken occasionally. Its enlarged foregut can ferment plant matter with the help of microbes, it feeds from about 200 different species of trees, and it prefers new leaves to mature ones. Snakes of the genus Python and birds of prey, including the crested serpent eagle, are its main predators.
