It is hard to guess what a Black-headed night monkey weights. But we have the answer:
An adult Black-headed night monkey (Aotus nigriceps) on average weights 1.06 kg (2.33 lbs).
The Black-headed night monkey is from the family Aotidae (genus: Aotus). When reaching adult age, they grow up to 35.7 cm (1′ 3″).
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 black-headed night monkey (Aotus nigriceps) is a night monkey species from South America. It is found in Bolivia, Brazil and Peru.
