Snake Movement. The key to snakes' agility -- hundreds of vertebrae and ribs -- is closely related to the key to their locomotion: ventral scales. These specialized rectangular scales line the underside of a snake, corresponding directly with the number of ribs. The bottom edges of the ventral scales function like the tread on a tire, gripping the surface and propelling the snake forward. Snakes have four basic methods of movement:
Once a snake is ready to eat, it opens its mouth wide and begins to walk its lower jaw over the prey as its backward-curving teeth grip the animal -- one side of the jaw pulls in while the other side moves forward for the next bite.The snake drenches the prey with saliva and eventually pulls it into the esophagus.hereas the upper jaw of a human is fused to the skull and therefore unable to move, a snake's upper jaw is attached to its braincase by muscles, ligaments and tendons, allowing it some front-to-back and side-to-side mobility.
