The indri Indri indri is the largest living lemur. In the wild, it is found only on the island of Madagascar.
Description
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
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.
A indri climbing between trees. Note the stub of a tail. The indri is the only "tailess" lemur [4].
Diet
The indri is predominantly a folivore that eats mainly immature leaves, but it also feeds on seeds, fruits and flowers[3][4].
Geographical distribution
The indri may be found in tropical moist lowlands and montane forests of eastern Madagascar[4].
