It is hard to guess what a Pennant’s colobus weights. But we have the answer:
An adult Pennant’s colobus (Procolobus pennantii) on average weights 9.16 kg (20.19 lbs).
The Pennant’s colobus is from the family Cercopithecidae (genus: Procolobus). When reaching adult age, they grow up to 56.9 cm (1′ 11″). Usually, Pennant’s colobuss 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.
Pennant’s colobus or Pennant’s red colobus (Piliocolobus pennantii) is a species of tree-dwelling primate in the family Cercopithecidae. It is endemic to tropical Central Africa. Three subspecies have traditionally been recognised but its distribution is peculiarly disjunct and has been considered a biogeographical puzzle. with one population on the island of Bioko (Equatorial Guinea), a second in the Niger River Delta in southern Nigeria, and a third in east-central Republic of Congo. It is found in rainforests and marshy forests. It is threatened by habitat loss and hunting for bushmeat. One subspecies, bouvieri, is rated as critically endangered; although it was last photographically documented in 2015, it may be on the brink of extinction.
