At a Glance
The Pig-tailed Langur is a primate found only on the Mentawai Islands off the west coast of Sumatra, Indonesia. There are two subspecies Simias concolor concolor, which lives on South Pagai, North Pagai and Sipora in the southern part of the archipelago, and Simias concolor siberu, which lives on Siberut in the northern part of the archipelago.
Both subspecies of langur live in tropical forests that can be swampy and mostly eat leaves of trees and plants, fruit, seeds and flowers.
The populations of Pig-tailed Langurs across the islands have dramatically fallen due to logging and hunting. The population that lives on Siberut is estimated to be around 14,000 monkeys and most of them live inside Siberut National Park. Primatologists estimate that between 700 and 1,800 langurs live on the southern islands in the Mentawai archipelago.
