Indri leap
This photo of course is a classic case of being too late. Yet, I wanted to share it anyway for educational purposes. These are the very long legs of an Indri, together with the diademed sifaka the largest kind of lemur, used to propel itself from trunk to trunk. When it comes to leaping, scientists distinguish between horizontal leapers and vertical leapers. The Indri is a vertical leaper. It does not mean it only jumps up, it means it keeps its upper body upright during leaping.

The indri, also called the babakoto, is one of the largest living lemurs. It is a diurnal tree-dweller related to the sifakas and, like all lemuroids, it is native to Madagascar.
