Purple-faced Langur (Semnopithecus vetulus)
Also known as the purple-faced leaf monkey, the purple-faced langur is a species of Old World Monkey (Cercopithecidae) that is endemic to Sri Lanka. Purple-faced langur typically occur in close canopy forests in Sri Lanka’s mountains and the southwestern part of the country known as the “wet zone”. Purple-faced langur are mainly folivorous (leaf eating) but are also known to feed on fruits, flower and seeds as well.
Currently Semnopithecus ventulus is listed as Endangered by the IUCN, as rapid urbanization has led to a significant decrease in their population level.
