Skin aids movement: worms

The skin of a worm allows it to move and change shape by having fibers wound in a cross-helical form around and along its body.

"The skin of a worm is a cylinder comprised of fibers wound in a cross-helical form around and along the worm's body. By contracting the muscles in the body wall and increasing its internal pressure, the worm is able to change shape, with the fibers in the skin allowing the worm to go from short and fat to long and thin."

Bioinspired products and application ideas

Application Ideas: The Centre for Biomimetics is studying worm locomotion and its implication for the development of artificial muscles. Cylinders of various fiber angles can be pieced together, and polymer gel used in place of muscles. By controlling swelling and contracting of the gel, researchers can effectively create an artificial muscle.

A close-up visual of the skin to see what is described would be helpful, if anyone has it.
