Indri

The indri (Indri indri) is a large lemur species native to Madagascar and the largest living member of its order. It belongs to the genus Indri in the family Indriidae and is endemic to the eastern rainforests of Madagascar. Indris are primarily arboreal and rely on the forest canopy for movement, feeding, and shelter. They are diurnal and are known for their distinctive, resonant vocalizations.

Physically, the indri is a robust primate with a body length of about 60 to 70 centimeters and a weight of roughly 6 to 9 kilograms. It has a dense coat that is typically dark with contrasting white patches on the shoulders and chest. Unlike many other lemurs, the indri has a very short tail. Its loud, far-carrying calls are a notable feature and serve to maintain group cohesion and advertise territory.

Ecology and behavior: indris live in small family groups, usually consisting of a wedded pair and their offspring. They feed mainly on leaves, with buds, fruit, and flowers composing a smaller part of the diet. The species sustains a low-energy diet and has a relatively slow reproductive rate, with a single infant commonly born after a gestation of about four months, and an interbirth interval of roughly two to three years.

Conservation status: the indri is listed as Endangered by the IUCN. Habitat loss from logging, slash-and-burn agriculture, and forest fragmentation threatens its populations. They are protected in several eastern Madagascar reserves and national parks, such as Andasibe-Mantadia National Park, but continued habitat protection and conservation actions are essential to prevent further declines.
