What is the maximal age a Spectral tarsier reaches?
An adult Spectral tarsier (Tarsius spectrum) usually gets as old as 12 years.
Spectral tarsiers are around 181 days in the womb of their mother. When born, they weight 24 grams (0.05 lbs) and measure 5 cm (0′ 2″). As a member of the Tarsiidae family (genus: Tarsius), their offspring is 1 babies per pregnancy. Fully grown, they reach a bodylength of 12 cm (0′ 5″).
As a reference: Usually, humans get as old as 100 years, with the average being around 75 years. After being carried in the belly of their mother for 280 days (40 weeks), they grow to an average size of 1.65m (5′ 5″) and weight in at 62 kg (137 lbs), which is obviously highly individual.
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).
