The dusky leaf monkey (Trachypithecus obscurus), also known as the spectacled langur or the spectacled leaf monkey, is a species of primate in the family Cercopithecidae. It is found in Peninsular Malaysia, Myanmar and Thailand,[2] and can occasionally be found in Singapore.[3] During the day, these small, folivorous primates divide in sub-groups and forage for vegetation and fruit throughout the tropical forests.[4][5] According to the IUCN, the dusky leaf monkey's population is declining due to habitat loss, poaching, and anthropogenic land use, which prompted the IUCN to classify the species as endangered in 2015.[2]
