Description[edit]

The indri is a diurnal primate that has a head body length of approximately 64 – 72 cm and a stubby vestigal tail ^[2]^[3]^[4]. Weight ranges between approximately 6kg up to almost 10kg ^[4]. Coat color varies from predominantly black contrasting with a white pygal patch and paler facial ring, to variegated black and white^[4]. Males can be difficult to distinguish from females, but in the Analamazaortra Special Reserve males are slightly larger than females and there is slight dimorphism in color pattern^[4].

Behaviour[edit]

The indri lives in small family groups^[3]. Its movement is described as vertical climbing and leaping and it maintains a preferential upright body posture^[4]. The indri has a loud vocalization which has been described as an “eerie wailing song” ^[4]which can be reminiscent of the singing of some whale species.

Diet[edit]

The indri is predominantly a folivore that eats mainly immature leaves, but it also feeds on seeds, fruits and flowers^[3]^[4].

Geographical distribution[edit]

The indri may be found in tropical moist lowlands and montane forests of eastern Madagascar^[4].
