How many baby Pygmy tarsiers are in a litter?
A Pygmy tarsier (Tarsius pumilus) usually gives birth to around 1 babies.
Upon birth, they weight 4 grams (0.01 lbs) and measure 5 cm (0′ 2″). They are a member of the Tarsiidae family (genus: Tarsius). An adult Pygmy tarsier grows up to a size of 10 cm (0′ 4″).
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 pygmy tarsier (Tarsius pumilus), also known as the mountain tarsier or the lesser spectral tarsier, is a nocturnal primate found in central Sulawesi, Indonesia, in an area with lower vegetative species diversity than the lowland tropical forests. The pygmy tarsier was believed to have become extinct in the early 20th century. Then, in 2000, Indonesian scientists accidentally killed one while trapping rats. The first pygmy tarsiers seen alive since the 1920s were found by a research team led by Dr. Sharon Gursky and Ph.D. student Nanda Grow from Texas A&M University on Mount Rore Katimbo in Lore Lindu National Park in August 2008. The two males and single female (a fourth escaped) were captured using nets, and were radio collared to track their movements. As the first live pygmy tarsiers seen in 80-plus years, these captures dispelled the belief among some primatologists that the species was extinct.
