How big does a Gelada get? Here is an overview over the average adult age:
A grown Gelada (Theropithecus gelada) reaches an average size of 62 cm (2′ 1″).
When born, they have an average size of 0 cm (0′ 0″). During their lifetime of about 28 years, they grow from 465 grams (1.03 lbs) to 15.98 kg (35.23 lbs). A Gelada has 1 babies at once. The Gelada (genus: Theropithecus) is a member of the family Cercopithecidae.
As a reference: Humans reach an average body size of 1.65m (5′ 5″) while carrying 62 kg (137 lbs). A human woman is pregnant for 280 days (40 weeks) and on average become 75 years old.
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.
