Creeper Mussel (Strophitus undulatus)
The Creeper Mussel is an obligate riverine species found in perennial streams where it prefers gravel substrates. Fish hosts include largemouth bass, creek cub, and green sunfish. It can also mature without going through a parasitic stage.
Current probable range would include portions of the Caney, Cottonwood, Elk, Fall, Little Osage, Marais des Cygnes, Marmaton, Neosho, Spring, Verdigris, and Walnut rivers and Grouse and Pottawatomie creeks.
