What is the maximal age a Grivet reaches?
An adult Grivet (Chlorocebus aethiops) usually gets as old as 31.58 years.
Grivets are around 82 days in the womb of their mother. When born, they weight 173 grams (0.38 lbs) and measure 7.6 cm (0′ 3″). As a member of the Cercopithecidae family (genus: Chlorocebus), their offspring is 1 babies per pregnancy. Fully grown, they reach a bodylength of 56 cm (1′ 11″).
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 grivet (Chlorocebus aethiops), also known as African green monkey and savannah monkey is an Old World monkey with long white tufts of hair along the sides of the face. Some authorities consider this and all of the members of the genus Chlorocebus to be a single species, Cercopithecus aethiops. As here defined, the grivet is restricted to Ethiopia, Sudan, Djibouti and Eritrea. In the southern part of its range, it comes into contact with the closely related vervet monkey (C. pygerythrus) and Bale Mountains vervet (C. djamdjamensis). Hybridization between them is possible, and may present a threat to the vulnerable Bale Mountains vervet. Unlike that species, the grivet is common and rated as Least Concern by the IUCN.
