The redear sunfish (Lepomis microlophus), also known as the shellcracker, Georgia bream, cherry gill, chinquapin, improved bream, rouge ear sunfish and sun perch, is native to the southeastern United States, but since it is a popular sport fish it has been introduced to bodies of water all over North America. It generally resembles the bluegill except for coloration and somewhat larger size. It is dark-colored dorsally and yellow-green ventrally. The male has a cherry-red edge on its operculum; females have orange coloration in this area. The adult fish is between 20 and 24 centimetres (7.9 and 9.4 in) in length. Max length is 43.2 centimetres (17.0 in), compared to a maximum of about 40 centimetres (16 in) for the bluegill.
