Worms use their muscles and setae, short bristly hairs, to move. The setae help them control their speed, and latch on to the ground. They have two kinds of muscles: circular and longitudinal. When they tighten their circular muscles they become long and thin, and their front end moves forward. Then they contract their longitudinal muscles to move their back end toward their front end.
