How old does a Japanese macaque get? (age expectancy)

What is the maximal age a Japanese macaque reaches?

An adult Japanese macaque (Macaca fuscata) usually gets as old as 33 years.

Japanese macaques are around 173 days in the womb of their mother. When born, they weight 502 grams (1.11 lbs) and measure 1.2 meter (4′ 0″). As a member of the Cercopithecidae family (genus: Macaca), a Japanese macaque caries out around 1 little ones per pregnancy, which happens around 1 times a year. Fully grown, they reach a bodylength of 82.7 cm (2′ 9″).

As a reference: Usually, humans get as old as 100 years, with the average being around 75 years. After being carried in the belly of their mother for 280 days (40 weeks), they grow to an average size of 1.65m (5′ 5″) and weight in at 62 kg (137 lbs), which is obviously highly individual.

A Japanese macaque gets as old as 33 years

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.
