This tarsier is endemic to the tiny volcanic island of Siau, Indonesia.
The volcano forms the northern part of the island, known as Karangetang and is one of Indoensia’s most active volcanoes. The volcano takes up 50% of the island’s geographic range, shrinking the size of potential habitat for the Siau Island tarsier – which is exacerbated by the relatively large human population that has converted virtually the entire primary habitat to some form of human use. Furthermore, the Siau Island tarsier is regularly eaten, with up to 5-10 animals consumed in one sitting.
