noun, plural: Siau Island tarsiers

A tarsier species that is found on the volcanic island of Siau, in North Sulawesi, Indonesia


Tarsiers are species of the family Tarsiidae of the order Primates. They are haplorrhines, i.e. dry-nosed, as opposed to Strepsirrhini primates, which are wet-nosed (rhinarium). The tarsiers are arboreal species and therefore are found in the rainforests. Tarsiers are characterized by their enormous eyes and large, thin ears relative to their head. Their eyes are also fixed in its skull. Their name (tarsier) is derived from another distinctive feature, i.e. having an elongated tarsus (ankle bone). This enables them to leap from tree to tree with ease.

Siau Island tarsiers are found on Siau Island, in North Sulawesi, Indonesia. The species is included in the list, The World's 25 Most Endangered Primates, by IUCN Species Survival Commission, Primate Specialist Group.1 They resemble Tarsius sangirensis but are taxonomically separable from them and other Sulawesian tarsiers based on their tail tuft (which has shorter and fewer fur that is lightly colored). Another distinctive feature is their reduced furriness of the tarsals. They also have whitish and pronounced paralabial hair. Their fur at the back lacks the golden brown coloration whereas the fur at the front is grayish in color.2
