Clingfishes and Singleslits: Gobiesocoidei

Clingfishes eat algae, body parts of sea urchins, small fishes, and small invertebrates (in-VER-teh-brehts), or are animals without backbones. Some are cleaner fishes that remove parasites from other fishes. Singleslits feed mainly on small, bottom-dwelling invertebrates. Algae (AL-jee) are plantlike growths that live in water and have no true roots, stems, or leaves. Parasites (PAIR-uh-sites) are animals or plants that live on other animals or plants without helping them and often harming them.
