It is hard to guess what a Golden-backed uakari weights. But we have the answer:
An adult Golden-backed uakari (Cacajao melanocephalus) on average weights 3.13 kg (6.9 lbs).
The Golden-backed uakari is from the family Cebidae (genus: Cacajao). They can live for up to 18 years. When reaching adult age, they grow up to 40 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.
The golden-backed uakari (Cacajao melanocephalus) or black-headed uakari, is a New World primate from the family Pitheciidae. It lives in the Amazon Rainforest, and is found in the countries of Brazil, Colombia, and Venezuela. It has black hair covering its body, except for a reddish abdomen, tail, and upper limbs, and a bald face. It has highly specialised teeth which allow it to eat seeds and fruits with hard shells. The name golden-backed uakari is a neotype proposed by Boubli et al. (2008).
