Litter Size

How many babies does a Spectral tarsier have at once? (litter size)

How many baby Spectral tarsiers are in a litter?

A Spectral tarsier (Tarsius tarsier) usually gives birth to around 1 babies.

Each of those little ones spend around 181 days as a fetus before they are released into the wild. Upon birth, they weight 23 grams (0.05 lbs) and measure 1.7 cm (0′ 1″). They are a member of the Tarsiidae family (genus: Tarsius). An adult Spectral tarsier grows up to a size of 12 cm (0′ 5″).

To have a reference: Humans obviously usually have a litter size of one ;). Their babies are in the womb of their mother for 280 days (40 weeks) and reach an average size of 1.65m (5′ 5″). They weight in at 62 kg (137 lbs), which is obviously highly individual, and reach an average age of 75 years.

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).
