It is hard to guess what a Gray-bellied night monkey weights. But we have the answer:
An adult Gray-bellied night monkey (Aotus lemurinus) on average weights 873 grams (1.92 lbs).
The Gray-bellied night monkey is from the family Cebidae (genus: Aotus). It is usually born with about 97 grams (0.21 lbs). They can live for up to 18 years. When reaching adult age, they grow up to 30.5 cm (1′ 1″). Usually, Gray-bellied night 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.
