The flying snake is a 4ft long snake found in Indonesia and Sri Lanka. It is a mildly venomous snake and earns its name through its anatomy. It has ridges in its belly that allows it to climb up trees, then the creature sucks in its abdomen and flares out its ribs to create a makeshift wing. In the air, flying snakes make a lateral undulation and the combination of these effects can carry them up to 100m. As it is more of a gliding motion, flying snakes only retain slight control over their in air trajectory.
