[7][8] The hands and feet of the lemur have prehensile "thumbs" and big toes, which allow it to maintain a superb grip on trunks and branches.

The big toe of the Milne-Edwards's sifaka and indrids in general is longer and has a deeper cleft compared to that of lemurids.

It leaping between trees, the Milne-Edwards's sifaka performs a 180 degree twist in midair so that it is facing the incoming landing target.

When landing, the Milne-Edwards's sifaka swings its tail and outstretched forearms downward to help keep the body forward much like a long-jumper.

P. edwardsi will solely use trees to traverse its habitat, however if forced to cross open area like roads it will use a bipedal sideways hop.

Adult lemurs typically do not fall although they may occasionally lose their grip if the bark of the tree shears off from beneath their fingers.

Milne-Edwards's sifaka is found in primary and secondary rainforests on the southeastern part of the island at elevations between 600 and 1,600 m (2,000 and 5,200 ft).

[5][12] The following lemur species can be found within the same geographic range as the Milne-Edwards's sifaka:[5][13] The behavior and social organization of P. edwardsi is particularly well studied.

The Milne-Edwards's sifaka's diet is composed primarily of both mature and immature leaves and seeds, but they also regularly consume flowers and fruit.

The groups provide protection from predators, while the size is limited by inter-group competition for seasonal feeding resources.

Group dynamics are probably dictated by balancing the benefits and costs of predation protection, inter-group competition for food resources, and mating opportunities.
