The bluegill (Lepomis macrochirus) is a species of freshwater fish sometimes referred to as bream, brim, or copper nose. It is a member of the sunfish family Centrarchidae of the order Perciformes. Lepomis, in Greek, means "scaled gill cover" and macrochirus means large hand, which may be a reference to its body shape. A defining characteristic of the bluegill is the bright blue edging visible on its gill rakers.
