Northern riffleshell (Epioblasma torulosa rangiana)

The northern riffleshell is an endangered freshwater mussel that was historically found in Illinois, Indiana, Kentucky, Michigan, Ohio, Pennsylvania, West Virginia, and western Ontario. It was widespread in the Ohio and Maumee River basins, and in tributaries of western Lake Erie. Today, the northern riffleshell occurs in short reaches of the Green River in Kentucky; the Detroit and Black Rivers in Michigan; Big Darby Creek in Ohio; and French Creek, LeBoeuf Creek and the Allegheny River in Pennsylvania. Restoration is ongoing in Illinois, Ohio, and West Viriginia.
