It is hard to guess what a Dusky leaf monkey weights. But we have the answer:
An adult Dusky leaf monkey (Trachypithecus obscurus) on average weights 7.18 kg (15.84 lbs).
The Dusky leaf monkey is from the family Cercopithecidae (genus: Trachypithecus). It is usually born with about 349 grams (0.77 lbs). They can live for up to 25 years. When reaching adult age, they grow up to 54.9 cm (1′ 10″). Usually, Dusky leaf monkeys 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.
