The Malayan Colugo (Galeopterus variegatus) or Flying Lemur isn’t really a Lemur and can’t really fly so we’ll stick to Colugo. What it can do very well however, is glide. Glides of 150m in horizontal distance have been recorded. I personally have seen them swerve trees mid flight. One of two species in the family Dermoptera, the Colugo is spectacularly odd.

The Malayan Colugo (Galeopterus variegatus) the most adept of the “flying” mammals, being able to glide up to 150m between trees while searching for young leaves and sap.
