Forty species of native freshwater mussels live within the refuge waters on the Ohio River. This includes six federally endangered mussel species: fanshell, pink mucket, sheepnose, spectaclecase, snuffbox, and rayed bean. Mussels are important to the health of a river ecosystem. They are filter feeders, which helps reduce silt, sediment, and pollutants in the water.
