The Sangihe tarsier ( Tarsius sangirensis ) is a primate species from the group of tarsier .

features

Sangihe tarsier are very small primates, but with 140 to 150 grams they are among the heaviest representatives of the tarsier from Sulawesi . Their fur is colored golden brown on the outside, the belly is white. The tail is longer than the body, in contrast to other tarsiers, the tuft of hair at the tip of the tail is only weakly pronounced. As an adaptation to the jumping way of life, the hind legs are elongated, the tarsus is enlarged. The gray-colored head has the large eyes typical of the Koboldmakis, the ears are also large, they are hairless and mobile.

distribution and habitat

These primates only live on the Indonesian island of Sangihe Besar , which is roughly halfway between Sulawesi and Mindanao . (The population of the neighboring island of Siau was described as a separate species - Siau-Koboldmaki - in 2008. ) The habitat of this species are forests such as rainforests and swamp forests, but also plantations. They can also be found in secondary forests .

Way of life

Sangihe tarsier, like all tarsier, are nocturnal tree dwellers who sleep in the plant thicket during the day. At night they go in search of food, while they move around by climbing and jumping. They live in small groups. In contrast to the closely related lemurs on Sulawesi, the groups split up for sleeping and also sleep higher up in the trees. This is probably a reaction to enemy pressure, for example from feral domestic cats .

Like all tarsier, these primates are carnivores likely to eat insects and small vertebrates.

Danger

It is not clear to what extent Sangihe goblin lemurs can cope with habitats that have been changed by humans, which is why statements about the endangerment are inconsistent. Due to the small size of their range, the lists IUCN the species as ( "high risk" endangered ).
