It is dark-colored dorsally and yellow-green ventrally. Unlike bluegill, the male has a cherry-red edge on its operculum; females have orange coloration in this area. The adult fish are between 20 and 24 cm (7.9 and 9.4 in) in length. Max length is 43.2 cm (17.0 in), compared to a maximum of about 40 cm (16 in) for the bluegill.
