A shieldtail snake was observed feeding on an earthworm, on a road. The earthworm was about the same length as that of the snake, and was slightly thinner than the snake. The snake first was observed to have caught the hold of the earthworm, later the snake started swallowing the earthworm. It took about an hour for the snake to swallow its prey. At first, both were on the edge of the road, afterwards the both of them went just beside the road - in the battle between prey and predator, twisting, curling around each other, dragging one another. Even when about 80% of the earthworm was swallowed, still its body and tail were seen moving and twisting.
