Draco cornutus
Draco cornutus is a species of "flying dragon", an agamid lizard. It is endemic to Borneo. It occurs at elevations up to  above sea level, although its distribution is poorly known.

Description 
The color of the gliding membrane, or patagia, of Draco cornutus depends on the habitat; populations of these lizards have adapted over time to match the color of local falling leaves. This adaptation provides them with camouflage from potential avian predators.
