Describe the skin of a snake?

The snake sheds. Most snakes shed their skins several times a year, and it can be a long process, sometimes over one week long. The snake starts by rubbing itself up against a rough surface such as a rock, tree, etc to make a tear in the dead skin. As the skin tears, the snake slowly wriggles its way out of the dead skin much like a person takes off dirty clothes.It is a remarkable process, and when finished, the whole snake skin can be very pretty(if albeit disgusting :) ) because in most species the skin is very detailed, so u can even see the skin that had covered the eyes and face.
