Sea Worms. The sea worms are a large and varied group of animals belonging to a group called annelida. They are segmented worms, and all bear at least some resemblance to the common earthworm. In the ocean, however, the worms have evolved many different appearances. One of the more interesting varieties is the tube worms. These animals form a hard-shelled tube that provides them protection.
