 | | As the snake grows, the number and the pattern of its scales stay the same, although a snake's scales are shed many times over the course of its life. |
 | | When the outer layer is ready to shed, the snake scrapes the edges of its mouth against a hard surface, such as a rock, until the outer layer begins to fold back around its head. |
 | | Like people, snakes grow quickly until they reach maturity, which can take one to nine years; however, their growth, though much slowed after maturity, never stops. |
