It is hard to guess what a Monk saki weights. But we have the answer:
An adult Monk saki (Pithecia monachus) on average weights 2.11 kg (4.65 lbs).
The Monk saki is from the family Cebidae (genus: Pithecia). It is usually born with about 119 grams (0.26 lbs). They can live for up to 24.58 years. When reaching adult age, they grow up to 41.1 cm (1′ 5″). Usually, Monk sakis 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.
The monk saki (Pithecia monachus) also known as Geoffroy’s monk saki or Miller’s monk saki, is a species of saki monkey, a type of New World monkey, from South America. It is found in forested areas of northwestern Brazil, northeastern Peru, eastern Ecuador and southeastern Colombia. This monkey can grow up to be 30 to 50 centimetres (12 to 20 in) long and weigh about 1 to 2 kilograms (2 lb 3 oz to 4 lb 7 oz), approximately the same as a large rabbit. The thick, bushy tail can be up to 25 to 55 centimetres (10 to 22 in) long. It has coarse fur, which is long and shaggy around the face and neck. A shy, wary animal, it is totally arboreal, living high in the trees and sometimes descending to lower levels but not to the ground. It generally moves on all fours but may sometimes walk upright on a large branch and will leap across gaps. During the day, it moves in pairs or small family groups, feeding on fruits, berries, honey, some leaves, small mammals such as mice and bats, and birds. The female gives birth to 1 young per mating season with the average family size being 4.5.
