It is hard to guess what a Gelada weights. But we have the answer:
An adult Gelada (Theropithecus gelada) on average weights 15.98 kg (35.23 lbs).
The Gelada is from the family Cercopithecidae (genus: Theropithecus). It is usually born with about 465 grams (1.03 lbs). They can live for up to 28 years. When reaching adult age, they grow up to 62 cm (2′ 1″). Usually, Geladas have 1 babies per litter.
As a reference: An average human weights in at 62 kg (137 lbs) and reaches an average size of 1.65m (5′ 5″). Humans spend 280 days (40 weeks) in the womb of their mother and reach around 75 years of age.
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.
