Formal Taxonomy
Animalia - Craniata - Actinopterygii - Scorpaeniformes - Cottidae - Cottus - Includes C. PHILONIPS, C. KAGANOWSKII, and C. CHAMBERLAINI, which formerly were regarded as distinct species (Lee et al. 1980). Hybridization with C. BAIRDI may contribute to morphological variation within some populations (Lyons 1990, which see for information on morphological variation in north-central U.S.). Formerly included in the order Perciformes; the 1991 AFS checklist (Robins et al. 1991) followed Nelson (1984) in recognizing the order Scorpaeniformes as distinct from the Perciformes.

Global Range
H - >2,500,000 square km (greater than 1,000,000 square miles) - H - Range includes Atlantic, Arctic, and Pacific basins of Alaska and most of Canada, south to Washington, Idaho, Montana, Iowa, St. Lawrence-Great Lakes basin, and Potomac River, Virginia; also eastern Siberia. In the north-central U.S., this species occurs primarily in three areas: Lake Superior and its tributaries, Lake Michigan, and small cold streams in the "Driftless Area" of southwestern Wisconsin, northeastern Iowa, and southeastern Minnesota (upper Mississippi River basin); between Driftless Area and Great Lakes occurs only in a few small streams and two small deep lakes, Trout and Big Green (Lyons 1990).
