Snakes really can fly ?
Chrysopelea is also known by its common name “flying snake.” It climbs using ridge scales along its belly, pushing against rough bark surface of tree trunks, allowing it to move vertically up a tree. Upon reaching the end of a tree’s branch, the snake continues moving until its tail dangles from the branch’s end. It then makes a J-shape bend, leans forward to select the level of inclination it wishes to use to control its glide path, as well as selecting a desired landing area. Once it decides on a destination, it propels itself by thrusting its body up and away from the tree, sucking in its abdomen and flaring out its ribs to turn its body into a “pseudo concave wing”,all the while making a continual serpentine motion of lateral undulation parallel to the ground to stabilise its direction in midair in order to land safely.
