It is hard to guess what a Crab-eating macaque weights. But we have the answer:
An adult Crab-eating macaque (Macaca fascicularis) on average weights 4.58 kg (10.1 lbs).
The Crab-eating macaque is from the family Cercopithecidae (genus: Macaca). It is usually born with about 329 grams (0.73 lbs). They can live for up to 38 years. When reaching adult age, they grow up to 51.5 cm (1′ 9″). On average, Crab-eating 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 crab-eating macaque (Macaca fascicularis), also known as the long-tailed macaque, is a cercopithecine primate native to Southeast Asia. It is referred to as the cynomolgus monkey in laboratories. It has a long history alongside humans; it has been alternately seen as an agricultural pest, sacred animal in some temples, and more recently, the subject of medical experiments.M. fascicularis lives in matrilineal social groups with a female dominance hierarchy, and male members leave the group when they reach puberty. It is an opportunistic omnivore and has been documented using tools to obtain food in Thailand and Myanmar. The crab-eating macaque is a known invasive species and a threat to biodiversity in several locations, including Hong Kong and western New Guinea. The significant overlap in macaque and human living space has resulted in greater habitat loss, synanthropic living, and inter- and intraspecies conflicts over resources.
