(See Fish Gallery Below) Although most sculpins are marine fishes (about 300 species), 28 species are found in freshwaters in North America; at least 9 species occur in Virginia. Sculpins are flattened, bottom-dwelling fish with large broad head and mouth, and fan-like pectoral fins. These small stream fishes add to the aquatic diversity and serve as links in the food chain and indicators of water quality. They live primarily on river bottoms and feed on benthic invertebrates.
