The mixture of sucking in its stomach and making a motion of lateral undulation in the air makes it viable for the snake to glide in the air, where it also copes to keep energy compared to travel on the ground and dodge terrestrial bounded predators. The concave wing that a snake generates in sucking its stomach flattens its body to up to double its width from back of the head to the anal vent, which is adjacent to the end of the snake’s tail, causes the cross section of the snake’s body to look like the cross section of a Frisbee or flying disc. When a flying disc spins in the air, the designed cross sectional concavity causes intensified air pressure under the center of the disc, causing lift for the disc to fly. A snake incessantly moves in lateral undulation to generate the identical effect of increased air pressure underneath its arched body to glide. It’d be interesting to know that flying snakes are capable to glide better than flying squirrels and other gliding animals, notwithstanding the lack of limbs, wings, or any other wing-like projections, gliding through the forest and jungle it inhabits with the distance being as great as 100 m. In the recent research conducted by the University of Chicago, the snake ability to glide has been an object of interest for physicists, and they found a correlation between size and gliding ability, in which smaller flying snakes were able to glide longer distance horizontally.
