Hello:

When a worm is crawling forward on the ground, it first bends its body in a "" shape(arches its back), then it lies down straightening its body, it repeats this movement again and again, so it can move forward.


Can I say the following sentence? Or something else to describe this body movement.
The worm arches along the ground.

Thanks.
