It is hard to guess what a Spectral tarsier weights. But we have the answer:
An adult Spectral tarsier (Tarsius spectrum) on average weights 166 grams (0.37 lbs).
The Spectral tarsier is from the family Tarsiidae (genus: Tarsius). It is usually born with about 24 grams (0.05 lbs). They can live for up to 12 years. When reaching adult age, they grow up to 12 cm (0′ 5″). Usually, Spectral tarsiers have 1 babies per litter.
As a reference: An average human weights in at 62 kg (137 lbs) and reaches an average size of 1.65m (5′ 5″). Humans spend 280 days (40 weeks) in the womb of their mother and reach around 75 years of age.
The spectral tarsier (Tarsius spectrum, also called Tarsius tarsier) is a species of tarsier found on the island of Selayar 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 genus Tarsius. While its range used to also include the population on nearby southwestern Sulawesi, this population has been reclassified as a separate species, Tarsius fuscus. Some of the earlier research published on Tarsius spectrum refers to the taxon that was recently reclassified and elevated to a separate species, the Gursky’s spectral tarsier (Tarsius spectrumgurskyae).
