Turbellarians: Turbellaria - Habitat

Most turbellarians live in freshwater or seawater, but a few species live on land. Many of the tiny species of turbellarians live between grains of sand in watery habitats. Larger species live in open water or among submerged materials such as rocks, coral, and algae (AL-jee), the plantlike growths that live in water and have no true roots, stems, or leaves. Many species live in invertebrates (in-VER-teh-brehts), which are animals without a backbone, or fishes without harming them. Land-dwelling turbellarians live in damp leaf litter and soil.
