Class Turbellaria are the nonparasitic, free-living flatworms. These worms have large eyespots and flaps on each side of the head to detect chemicals. These worms live in water, usually on the underside of rocks. They have a highly branched digestive tract, but the one opening, or mouth, is on the ventral surface, rather than in the anterior end. The tube extending from the mouth is used to suck in materials as the worm uses cilia to crawl on the floor of the water.

Turbellaria and Nemertea are common and often very numerous inhabitants of freshwaters. Even though more than 200 species of Turbellaria and 3 species of Nemertea live in North America, their ecology and systematics have been less studied than that of many other common aquatic invertebrates. Most turbellarians become unrecognisable after a routine preservation of field samples in alcohol or formalin.

Turbellarians are predominately free-living and aquatic. They have an incomplete digestive tract, in which the mouth leads to a pharynx, then to temporary spaces containing cells that take in food particles by phagocytosis. Digestion is intracellular. These animals move by laying down slime from special skin glands, then gliding along these "slime trails" by the beating of epidermal cilia.
