Why Do Snakes Shed Their Skins?
On its surface, the snake grows a layer of cutin scales, which are called the s skin. The snake’s cutin scales don’t grow. Once every few months, the outgrows its skin. Thin order to grow, the snake must escape from its tight, small and narrow "clothes'.
When it is time for shakes to shed their skins, they become very slow in action, and they can't see very dearly.
When the snake sheds the skin, the shake first rubs its mouth against a rough place. When the skin on the month becomes loose, the head comes out before the whole skin sheds off the tail.
