It is hard to guess what a Sooty mangabey weights. But we have the answer:
An adult Sooty mangabey (Cercocebus atys) on average weights 6.94 kg (15.3 lbs).
The Sooty mangabey is from the family Cercopithecidae (genus: Cercocebus). It is usually born with about 527 grams (1.16 lbs). They can live for up to 26.75 years. When reaching adult age, they grow up to 21.1 cm (0′ 9″). Usually, Sooty mangabeys 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 sooty mangabey (Cercocebus atys) is an Old World monkey found in forests from Senegal in a margin along the coast down to Ghana. While overall rated as Near Threatened, the eastern race lunulatus, also known as the white-crowned, white-naped, or white-collared mangabey (leading to confusion with the collared mangabey), is considered Endangered by the IUCN. The White-collared mangabey was declared its own species by the IUCN in 2016, but it retains the endangered conservation status.
