|Spectral tarsier (Tarsius tarsier) range (including the recently split Tarsius fuscus)|
The spectral tarsier (Tarsius spectrum also called Tarsius tarsier) is a species of tarsier found in Indonesia. It is apparently less specialized than the Philippine tarsier or Horsfield's tarsier; for example, it lacks adhesive toes. It is the type species for the Tarsius genus. While its range used to include both the population on the island of Selayar as well as on nearby southwestern Sulawesi, the latter populations has been removed to a separate species, Tarsius fuscus.
When considered to include Tarsius fuscus in measurements females weigh between 102 and 114 grams (3.6 and 4.0 oz) while males are 118 to 130 grams (4.2 to 4.6 oz). It has a head-body length of 9.5 to 14 centimetres (3.7 to 5.5 in) and its tail length ranges from 20 to 26 centimetres (7.9 to 10.2 in). The average lifespan in the wild is thought to be 10 years, however in captivity the closely related Horsfield's tarsier can live up to 17 years and it is thought the spectral tarsier may have a similar longevity.
