Head triangular; eye large; snout blunt, its length usually greater than eye diameter; mouth terminal, lower jaw usually projecting beyond upper, sometimes equal to upper jaw, maxillary pigmented , and extending posteriorly to below the anterior edge of the pupil. Overall coloration dark silvery, with pink or purple iridescence on sides, back dark green to black and silvery below. Maxillary and mandible whitish but heavily pigmented. All fish typically black, particularly on outer half.
Body shape (shape guide): fusiform / normal; Cross section: compressed.
Formerly found in deep waters (90-160 m) of Lakes Michigan and Huron, and in 2-100 m in Lake Nipigon. Belongs to C. artedi complex.
