The scales however grow larger in size and may change shape with each moult.

Just prior to shedding, the skin becomes dull and dry looking and the snake's eyes turn cloudy or blue-coloured. The old layer of skin splits near the mouth and the snake wriggles out, aided by rubbing against rough surfaces. In many cases the cast skin peels backward over the body from head to tail, in one piece like an old sock.
