How big does a Japanese macaque get? Here is an overview over the average adult age:
A grown Japanese macaque (Macaca fuscata) reaches an average size of 82.7 cm (2′ 9″).
When born, they have an average size of 0 cm (0′ 0″). During their lifetime of about 33 years, they grow from 502 grams (1.11 lbs) to 10.11 kg (22.28 lbs). Talking about reproduction, Japanese macaques have 1 babies about 1 times per year. The Japanese macaque (genus: Macaca) is a member of the family Cercopithecidae.
As a reference: Humans reach an average body size of 1.65m (5′ 5″) while carrying 62 kg (137 lbs). A human woman is pregnant for 280 days (40 weeks) and on average become 75 years old.
The Japanese macaque (; Macaca fuscata), also known as the snow monkey, is a terrestrial Old World monkey species that is native to Japan. They get their name “snow monkey” because some live in areas where snow covers the ground for months each year – no other non-human primate is more northern-living, nor lives in a colder climate. Individuals have brown-grey fur, pinkish-red faces, and short tails. Two subspecies are known.In Japan, the species is known as Nihonzaru (ニホンザル, a combination of Nihon 日本 “Japan” + saru 猿 “monkey”) to distinguish it from other primates, but the Japanese macaque is very familiar in Japan, so when Japanese people simply say saru, they usually have in mind the Japanese macaque.
