Climbing snakes fold up like a harmonica
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.
