==Concertina locomotion==

==Concertina locomotion==

This is common in burrowing snakes and can be seen when a snake crawls through a tube. While the back half of the body acts as an anchor the front half is pushed forward. The back half is then drawn forward.

==Rectiliniear crawling==

==Rectilinear crawling==

The edges of the scales act as anchor points and the muscles then pull the body up to that point. This is often used by large snakes.

==Sidewinding==

This is similar to concertina locomotion but the angle of movement is at 45 degrees to the direction that the snake is pointing.
