Snakes move without legs by utilizing a motion called "serpentine locomotion" or "slithering." Instead of relying on limbs, snakes have adapted their bodies for efficient and agile movement. They use a combination of muscular contractions and friction with the environment to propel themselves forward.
During slithering, a snake pushes against the ground or other objects with its belly scales, creating friction that propels it forward. The snake's muscles contract and relax in waves along its body, causing a series of bends or curves to move along its length. As each curve passes backward, it pushes against the surface, propelling the snake forward.
This motion allows snakes to navigate diverse terrains, including grass, sand, rocks, and even trees. They can adjust the speed and direction of their movement by altering the frequency and intensity of their muscular contractions. By using their bodies' flexibility and unique scales, snakes have evolved a remarkable mode of locomotion that enables them to thrive in various environments.
