Identification: A small catfish with a long, slender body and a straight to slightly rounded caudal fin margin. Color is dark grey on the back and sides, with a light spot just behind the dorsal fin, and white belly. As with other madtoms, the adipose fin is fused with the caudal fin, which distinguishes it from the bullheads and larger catfish species. Adults grow to about 12 in.
Distribution and Habitat: Common in the eastern half of the state, where it inhabits swift, rocky riffles of streams and rivers.
