An example of annelids are earthworms. They are segmented worms, and is the segments and what separates them (septa) that are largely responsible for locomotion. Movement occurs through a series of constriction and relaxation of the muscles along the worm. This is called peristalsis, and is how food travels down the esophagus after you swallow your food.
In addition to peristalsis, some worms have "hairs" (called chetae) along their bodies. They provide traction for the worm's body which is required for the worm to move. They can also be used to grip onto the soil if a predator such as a bird attempts to pluck it out of the ground.

∙ 10y agoNerve-activated muscles are how nematodes move.
Specifically, the roundworm in question (Nematodaphylum) has a cuticle-covered epidermis (skin) over muscles controlling movement. The muscles lie lengthwise, not widthwise. The back's dorsal nerve and the belly's ventral nerve will activate the muscles when the nematode needs to effect thrashing locomotions while lying on one side.
