Shell Anatomy
 

Found in four river basins in NC (Catawba, Pee Dee, Cape Fear, Neuse), the brook floater is also distributed along the Atlantic coast from SC to Canada.

 

Brook floaters prefer swift current in run-riffle complexes with clean gravel/sand/cobble substrates.

The host fish species include the margined madtom, pumpkinseed, golden shiner, and yellow perch.
