Spectral Tarsier

Dinner-plate eyes in the dark — leaping Sulawesi primate with a voice like a camera shutter.

Vulnerable

Tarsius tarsier

Overview

Spectral tarsiers are tiny nocturnal primates of Sulawesi, famous for enormous fixed eyes and powerful leaping hind legs. They hunt insects by night and park in dense thickets or fig trees by day, often in small family groups.

For Indonesia collectors, the spectral tarsier is a rare Wallacean night card — huge eyes, vertical leaps, and pure Sulawesi endemism.

Habitat

  • Sulawesi forest
  • Secondary thicket
  • Coastal scrub

Primary and secondary forest, scrub, and coastal thickets of Sulawesi and nearby islands, favouring dense vertical supports for clinging and leaping.

Field notes

Field scale for the Spectral Tarsier: length around 10-15 cm body; tail ~20-25 cm; weight 100-150 g. Typical lifespan: Around 8-12 years in the wild.

When you are scanning habitat, prioritise sulawesi forest, secondary thicket, and coastal scrub. Those settings are where a clean look and a usable photo are most likely.
