Four.

Life span
12 years.

Statistics

Physical description
Spectral tarsiers have short forelimbs and long hind-limbs for jumping, with large eyes. They have a white spot behind each ear and long hair on the lower half of the tail. The tail is long to help them balance, and the tips of their digits have evolved into disk-like pads, to aid in gripping branches.

Distribution
They live in Sulawesi, Indonesia.

Habitat
Spectral tarsiers inhabit primary and secondary tropical forest.

Diet
They feed solely on insects.

Behaviour
Spectral tarsiers are nocturnal and arboreal, although they often descend to the ground to hunt insects. They may live in pairs, or in multimale-multifemale groups, with up to six members. The group forages and sleeps together. They move by clinging and leaping between vertical supports (tree trunks and branches).

Reproduction
Females give birth to one infant after a gestation period of 184-194 days. The female carries her infant in her mouth, but leaves it on a branch while she is foraging.

Conservation status
Spectral tarsiers are considered by the 2000 IUCN Red List to be at Lower Risk of extinction.
