What is the maximal age a Gelada reaches?
An adult Gelada (Theropithecus gelada) usually gets as old as 28 years.
Geladas are around 178 days in the womb of their mother. When born, they weight 465 grams (1.03 lbs) and measure 36.8 cm (1′ 3″). As a member of the Cercopithecidae family (genus: Theropithecus), their offspring is 1 babies per pregnancy. Fully grown, they reach a bodylength of 62 cm (2′ 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 gelada (Theropithecus gelada, Amharic: ጭላዳ, romanized: č̣əlada), sometimes called the bleeding-heart monkey or the gelada “baboon”, is a species of Old World monkey found only in the Ethiopian Highlands, with large populations in the Semien Mountains. Geladas are actually not baboons (baboons are all taxonomic members of the genus Papio) but the only living members of the genus Theropithecus. Theropithecus is derived from the Greek root words for “beast-ape”. Like its close relatives the baboons (genus Papio), it is largely terrestrial, spending much of its time foraging in grasslands.
