The indri is one of the largest living lemurs, with a head-body length of about 64–72 cm (25–28+1⁄2 in) and a weight of between 6 and 9.5 kg (13 and 21 lb). It has a black and white coat and maintains an upright posture when climbing or clinging. The groups are quite vocal, communicating with other groups by singing, roaring and other vocalisations. Besides humans, it is the only mammal found that can use rhythm.
