The indri (Indri indri) is one of the largest living lemurs, with a head-body length of 64-72 cm and can reach nearly 120 cm with legs fully extended. Its weight is between 6 and 9.5 kg. Its large greenish eyes and black face are framed by round, fuzzy ears. The silky fur is mostly black with white patches along the limbs, neck, crown, and lower back. Some northern populations consist of mostly or entirely black individuals. The face is bare with pale black skin, and it is sometimes fringed with white fur. The indri maintains an upright posture when climbing or clinging. Unlike any other living lemur, the indri has only a rudimentary tail.
