The pig-tailed snub-nosed monkey weighs about 7 kg (15 lb). It lives in primary forest, where it is primarily arboreal, only descending to the ground when disturbed. Its diet consists mostly of leaves and some fruit and berries. Most observed social groups are small (3-8 monkeys). These may be harem groups with more than 1 adult female or a monogamous group consisting of an adult pair and its young. Groups containing about 20 individuals have been observed in primary forest. Home ranges of 3.5 - 20 hectares (8.8 - 50 acres) have been observed. (Davies & Oates 1994).The pig-tailed snub-nosed monkey has only been recorded from the Mentawai Islands, off the west coast of Sumatra, Indonesia. In 1987 it was thought to occur on Siberut, Sipora, Pagai Utara, Pagai Seletan, and a small islet near the Katurei Peninsula, Siberut. Reasons for its decline include hunting for food and habitat loss, mainly due to logging.
