It is hard to guess what a Rio Tapajós saki weights. But we have the answer:
An adult Rio Tapajós saki (Pithecia irrorata) on average weights 2.31 kg (5.1 lbs).
The Rio Tapajós saki is from the family Cebidae (genus: Pithecia). When reaching adult age, they grow up to 39.9 cm (1′ 4″).
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.
