Flying snakes are a small species of tree snakes that live in South and Southeast Asia. On the ground these snakes seem normal but on the move they're able to take to air, jumping from tree to tree, by flattening out the entire body and gliding or parachuting to the ground or another tree.
Flying snakes are even better gliders then flying squirrels. While flying squirrels can glide up 60 meters from one tree to another, flying snakes can glide up to 100 meters or more, and they actually "slither" in mid air which gives them better stability and some degree of control while they're gliding. Flying snakes are venomous but are not dangerous to humans. They feed mostly on lizards or other small animals, and spend most of their time up on trees.
