How do the snakes do it? The don't really fly, per se, but rather fall with purpose. The snakes climb to the tops of the tallest trees, some 200 feet in the air, and then take a leap. But their method for turning their elongated forms into aerodynamic vehicles is pretty amazing, allowing them to travel nearly 800 feet laterally as they descend. They do this by first falling to pick up speed, then by initiating a strange aerial dance that essentially turns their bodies into one long wing. Some of them can actually pull off a turn in the air.
