A Version of a Flying Dragon from Avatar
This little creature has features similar to that of Toruk, a fierce airborne predator almost impossible to tame. You'll see photos of its mini version in nature. Who knows, maybe Cameron was inspired by this little beast.
Pictures of this lizard were taken in the Lambusango Forest reserve in Buton, Indonesia. The most interesting thing, the lines that you see on its "wings" are actually its ribs.
