The largest living lemur

The indri is a black-and-white lemur with a very short tail, long legs and rounded ears. It clings upright to tree trunks and makes huge leaps between them.

A family chorus

Indri family groups sing together in a wailing chorus that can be heard for around two kilometres. Songs mark territory and help groups avoid each other, and each song has a distinct structure. Their song is one of the most recognisable sounds of Madagascar’s forests.

Critically endangered

Indris depend on large patches of intact forest and cannot survive in captivity. Slash-and-burn farming and illegal logging have caused rapid decline, so protecting the remaining forest is vital.
