What is the maximal age a Tana River mangabey reaches?
An adult Tana River mangabey (Cercocebus galeritus) usually gets as old as 21 years.
Tana River mangabeys are around 174 days in the womb of their mother. When born, they weight 1 grams (0 lbs) and measure 2.9 cm (0′ 2″). As a member of the Cercopithecidae family (genus: Cercocebus), their offspring is 1 babies per pregnancy. Fully grown, they reach a bodylength of 51 cm (1′ 9″).
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 Tana River mangabey (Cercocebus galeritus) is a highly endangered species of primate in the family Cercopithecidae. Some authorities have included the taxa agilis and sanjei as subspecies of this species, while others award these full species status.It is endemic to riverine forest patches along the lower Tana River in southeastern Kenya. It is threatened by habitat loss and degradation, which has increased in recent years. This species was, together with the equally endangered Tana River red colobus, the main reason for the creation of the Tana River Primate Reserve in 1978, but human encroachment within this reserve continues. Recently, it has been suggested that 20,000 hectares of the Tana River Delta should be transformed into sugarcane plantations, but this has, temporarily at least, been stopped by the High Court of Kenya.
