Indri indri (Indri)
The Indri Indri Indri is the largest living Lemur. In the wild, it is found only on the island of Madagascar.
The Indri has a head body length of approximately 64 – 72 cm and has a stubby vestigal tail [1][2][3]. Weight ranges between approximately 6kg up to almost 10kg [3]. Coat color varies from predominantly black contrasting with a white pygal patch and paler facial ring, to variegated black and white[3]. 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[3].
Its movement is described as vertical climbing and leaping and maintains a preferential upright body posture[3]. The indri has a loud vocalization which has been described as an “eerie wailing song” [3]and can be reminiscent of the singing of some whale species.
Geographical distribution
The indri may be found in tropical moist lowlands and montane forests of eastern Madagascar[3].
