[3] Tarsiers are small, agile primates, adapted for climbing, leaping and foraging at night.

The adult weight is generally between 100 and 140 g (3.5 and 4.9 oz), with males tending to be slightly larger than females.

Secondary forest occupies about 63% of the island, making 72% of the surface area potentially providing suitable habitat.

[5] During the day they sleep in concealed locations in tangled vegetation a few metres off the ground, emerging at dusk to forage during the night.

Due to the great similarity of these calls to those of Dian's tarsier (Tarsius dentatus), the two species are thought to be closely related.
