The indri, also called the babakoto, is the largest living lemur.
It has a head-and-body length of about 64–72 cm (25–28 in) and weight of between 6-9.5 kg (13-21 lb).
It has a black and white coat and maintains an upright posture when climbing or clinging to trees.
It is monogamous and lives in small family groups, moving through the canopy, feeding mainly on leaves but also seeds, fruits, and flowers.
The groups are quite vocal, communicating with other groups by singing, roaring and other vocalisations.
It is a diurnal tree-dweller related to the sifakas and, like all lemurs, it is native to Madagascar.
It is revered by the Madagascan people and plays an important part in their myths and legends with various stories accounting for its origin.
The main threats faced by the indri are habitat destruction and fragmentation due to slash and burn agriculture, fuelwood gathering, and logging.
It is also hunted despite taboos against this, and the International Union for Conservation of Nature has rated its conservation status as "critically endangered".
