Sand-coloured macaque ( Macaca mulatta ), widespread in South and Southeast Asian forests.
Rhesus monkeys are 1725 in. (4364 cm) long, excluding the furry 812-in. (2030-cm) tail, and weigh 1024 lb (4.511 kg). They eat fruits, seeds, roots, herbs, and insects. They are held sacred in some parts of India. Hardy in captivity, highly intelligent, and lively, they make good pets when young but may become bad-tempered as adults. They have been used frequently in medical research. The determination of the Rh (from rhesus) factor in human blood involves reaction with the blood of this species. See also Rh blood-group system .
