   ocr: MOVEMENT ON LAND M OST land have ANIMALS legs that that move support on their weight and move them - in a coordinated way in the direction in which they want to travel. Animals without legs, such as snakes, have to cope with the friction between their body and the ground. Snakes have a smooth-scaled skin to reduce friction. They slide along the ground by contracting muscle blocks attached to a flexible backbone. Sidewinder This desert snake travels rapidly across the sand by sideways movements. In this way it avoids touching the very bot. sand for long.
