Spectacled Leaf Monkey - Trachypithecus obscurus
Also referred to as Dusky Leaf Monkey, Spectacled Langur, and Dusky Langur, Trachypithecus obscurus (Primates - Cercopithecidae) is a Near Threatened species of monkey native to Malaysia, Myanmar and Thailand, which inhabits a range of forest habitats including coastal and riverine settings.
These monkeys are quite distinctive by their thick white eye-rings and upper lip, and by the tufts of fur on the cheeks. They are diurnal, primarily arboreal, and folivorous, although the diet is relatively varied and the animals will also consume fruit, flowers and other items. They are able to take advantage of unripe fruit, which have chemical defenses, by the same means that they break down toxins in plant leaves, using the bacteria found in their digestive system.
