Dusky leaf monkey

Mammals

The dusky leaf monkey, Trachypithecus obscurus, also called the spectacled langur or spectacled leaf monkey, is a small, mostly leaf-eating primate of the family Cercopithecidae found in Peninsular Malaysia, Myanmar and Thailand, with a few animals occasionally seen in Singapore. It is born with an orange coat that changes as it matures, with lighter fur on the abdomen than on the back, which can be brown, black or grey, and bright white circles of fur around the eyes. In one study males averaged 7.39 kg and females 6.47 kg. During the day it divides into sub-groups to forage for vegetation and fruit in tropical forests, and it has no seasonal mating period. Seven subspecies are officially recognised. The IUCN classified it as endangered in 2015 because habitat loss, poaching and land use are shrinking its population, and road mortality is one of the more prominent threats.
