The Freshwater Information Network is an initiative to provide an online database of freshwater life.
The Quillback is widespread from Florida to western Canada, including the Mobile Basin, Tennessee, and Cumberland river drainages. They live in many different habitats, though predominately in large rivers. As their common name suggests, Quillbacks have a long and highly curved dorsal fin that is adapted for life in large rivers.
