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:
A snake may appear threatening when it flicks its tongue out, but it's simply trying to get a better sense of its surroundings by tasting the air. To compensate for their poor eyesight and limited hearing, most snakes have an excellent sense of smell. Although snakes have nostrils, they also use their tongues to pick up the scent of nearby prey or predators. When a snake flicks its tongue, it collects odors that are present in miniscule moisture particles floating through the air. The snake darts the tongue into its Jacobson's organ, which is located inside the roof of the snake's mouth.
