It is hard to guess what a Chacma baboon weights. But we have the answer:
An adult Chacma baboon (Papio ursinus) on average weights 17.73 kg (39.09 lbs).
The Chacma baboon is from the family Cercopithecidae (genus: Papio). It is usually born with about 599 grams (1.32 lbs). They can live for up to 45 years. When reaching adult age, they grow up to 1.72 meter (5′ 8″). Usually, Chacma baboons 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 chacma baboon (Papio ursinus), also known as the Cape baboon, is, like all other baboons, from the Old World monkey family. It is one of the largest of all monkeys. Located primarily in southern Africa, the chacma baboon has a wide variety of social behaviors, including a dominance hierarchy, collective foraging, adoption of young by females, and friendship pairings. These behaviors form parts of a complex evolutionary ecology. In general, the species is not threatened, but human population pressure has increased contact between humans and baboons. Hunting, trapping, and accidents kill or remove many baboons from the wild, thereby reducing baboon numbers and disrupting their social structure.
