Gliding snakes

Some tree snakes have evolved the ability to flatten themselves, essentially turning their bodies into a concave wing. The aerodynamics of their gliding motion is similar to that of a frisbee, and they can fly for as far as 100 meters.

Their flying ability is so unique that it has recently attracted the interest of physicists who want to understand how these snakes can slither through the air.

Some snakes have been observed making sharp 90-degree turns while gliding. (Check out these incredible videos of flying snakes.)
