When a snake grows, its outer skin layer called epidermis does not grow or get bigger with it. Hence, the snake sheds its epidermis periodically to allow further growth of its body. In addition to this, shedding also helps remove parasites present on the epidermis.
Before shedding, the snake grows a new epidermis beneath the old one and secretes a fluid between the old and new epidermis. This fluid helps separate the old epidermis from the new one. Once this is done, the process of shedding begins. To remove the old epidermis, the snake rubs its head against any hard surface, creating a tear either near mouth or near nose area. Then, it drags and wriggles it body against any hard surface and slowly slithers out of the old epidermis.
