How old does a Rhesus macaque get? (age expectancy)

What is the maximal age a Rhesus macaque reaches?

An adult Rhesus macaque (Macaca mulatta) usually gets as old as 36 years.

Rhesus macaques are around 166 days in the womb of their mother. When born, they weight 472 grams (1.04 lbs) and measure 1.2 meter (4′ 0″). As a member of the Cercopithecidae family (genus: Macaca), a Rhesus macaque caries out around 1 little ones per pregnancy, which happens around 1 times a year. Fully grown, they reach a bodylength of 55.5 cm (1′ 10″).

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.
