Female (from the blue smudge on its neck) Common Flying Dragon (Draco sumatranus) snapped in Sungei Buloh mangroves, Singapore.
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.
