How much does a Peruvian night monkey weight?

It is hard to guess what a Peruvian night monkey weights. But we have the answer:

An adult Peruvian night monkey (Aotus miconax) on average weights 800 grams (1.76 lbs).

The Peruvian night monkey is from the family Cebidae (genus: Aotus). When reaching adult age, they grow up to 30.5 cm (1′ 1″).

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 chest, belly and upper arms are orange tinged, however, to a lesser extent then Aotus nigriceps.The species is one of the least known and possibly rarest Neotropical primates. This species is listed as vulnerable by the IUCN and endangered under Peruvian Law.The Peruvian night monkey is also one of the least studied of all primates. The only data that exists about this species are museum specimens, sighting records and very basic ecological information. The species is thought to inhabit areas of cloud forest at 900–2,800 m (3,000–9,200 ft) above sea level in the departments of Amazonas, Huanuco and San Martin, and in border regions of neighboring departments.
