The Hoop Snake is so named due to its very unique method of locomotion. They catch their tail in their mouths, forming a large circle, and roll rapidly downhill, either to escape nearby predators, or to attack possible predators at the bottom of the hill, hoping to injure them so they may escape in the confusion. The snake fields mostly on small mammals, swallowing their prey whole, although they are a venomous snake.
