What is the maximal age a Guianan squirrel monkey reaches?
An adult Guianan squirrel monkey (Saimiri sciureus) usually gets as old as 27 years.
Guianan squirrel monkeys are around 164 days in the womb of their mother. When born, they weight 108 grams (0.24 lbs) and measure 4 cm (0′ 2″). As a member of the Cebidae family (genus: Saimiri), their offspring is 1 babies per pregnancy. Fully grown, they reach a bodylength of 32.2 cm (1′ 1″).
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 Guianan squirrel monkey (Saimiri sciureus) is a species of squirrel monkey from Guiana, Venezuela and Brazil. S. scuireus formerly applied to Humboldt’s squirrel monkey and Collins’ squirrel monkey, but genetic research in 2009 and 2015 revealed that these are distinct species.
