noun, plural: Lariang tarsiers

A tarsier species that is found in the Lariang River basin of 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.

Lariang tarsiers are found in the Lariang River basin of Sulawesi, Indonesia (thus, the name).1 Their habitats include the drainage basin, mangrove swamp, forest, scrubland, etc. Compared with other tarsier species in Sulawesi, the Lariang tarsiers have a darker fur, which is grayish brown. They are the second largest tarsier species next to Sangihe tarsiers. The Lariang tarsiers have body weights ranging from 67 to 117 g.
