Slithering refers to slide down or along a surface, especially unsteadily, from side to side, or with some friction or noise. A snake moves forward by moving its body sideways in the form of many loops and pushing against the ground. It contracts and relaxes its muscles on the two sides of its body alternately to form many loops in which different parts of the snake’s body are moving to the left side and right side at the same time. The wave-like motion of a snake is called slither. The snakes slither on ground by looping sideways.
