North America: Virginia and West Virginia, USA. Cottus kanawhae prefers the rocky areas of limestone streams and, like C. carolinae, abounds in cave streams. Restriction of habitat during the breeding season, if any, is unknown. During other seasons, there are no obvious ecological distinctions between C. kanawhae and C. b. bairdii.

Morphology | Morphometrics
Pectoral-fin rays usually 17 (15–18). Lateral line incomplete, typically not extending beyond the point of deflection; pores usually 26–29 (24–34). Chin pigmentation reduced, the mottling usually restricted to the rami of the jaws and front of the chin, rarely extending back onto the anterior part of the isthmus. Anterior chin pore double. Dark bands on the body not sharply defined, irregular, extending ventrad only slightly below the lateral line.
