It is hard to guess what a Rhesus macaque weights. But we have the answer:
An adult Rhesus macaque (Macaca mulatta) on average weights 6.45 kg (14.23 lbs).
The Rhesus macaque is from the family Cercopithecidae (genus: Macaca). It is usually born with about 472 grams (1.04 lbs). They can live for up to 36 years. When reaching adult age, they grow up to 55.5 cm (1′ 10″). On average, Rhesus macaques can have babies 1 times per year with a litter size of 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 rhesus macaque (Macaca mulatta) is a species of Old World monkey. It is listed as least concern in the IUCN Red List of Threatened Species in view of its wide distribution, presumed large population, and its tolerance of a broad range of habitats. It is native to South, Central, and Southeast Asia and has the widest geographic range of all non-human primates, occupying a great diversity of altitudes and a great variety of habitats, from grasslands to arid and forested areas, but also close to human settlements.
