The snake's gliding abilities are no match for a bird's, but they compare pretty well to those of flying squirrels, ants and lizards.

Mystery maneuver

To get airborne, the snakes grasp a tree branch with their tail, then launch upwards.

They also seem to curl up and splay their ribs out to flatten their bodies, while undulating in the air.

UFO Shape

Looked at in cross section, their flattened bodies resemble UFOs or rounded triangles, a shape that isn't typically found in engineered or natural flying objects.

Aerodynamic properties

To see why the snakes flattened out, researchers at Virginia Tech made a 3-D model of the snake and put it into a flow chamber. The shape was surprisingly aerodynamic.

Now, the researchers need to find out why the snake undulates as it glides.
