Science Illustrated - - ASK US -

The forepart and hind part of the body take turns to get a grip in a har­mon­ica-like mo­tion, as snakes move from one branch to the next.

1. First, the snake folds up its body.

2. Sub­se­quently, the snake moves the front part of its body for­wards.

3. When the snake has got­ten a good grip at its front end, it will move the back of its body for­ward.
