The median lifespan of macaques in the wild is less than 15 years . Stump-tailed macaques are very social and live in groups of up to individuals. These groups consist of adult males, females, and young. Females stay in their natal groups and males leave after sexual maturity.

Adult males measure about 53 cm (21 in) on average and weigh about kg (17 lb). Females are smaller, averaging 47 cm (19 in) in length and kg (12 lb) in weight. The ratio of arm length to leg length is 89%.  The rhesus macaque has a dental formula of × 2 = 32 and bilophodont molar teeth.
They are cm long on average, and weigh 4,8 – 13,5 kilograms, while their build is stocky and they are in fact very strong animals.
