How to identify a Bluegill
The Bluegill has a greatly compressed, round (in profile) body that is typical of the sunfishes. Its color is highly variable and many range from dark blue or bluish-purple to yellow, and in some cases, (notably in quarry holes) it may even appear to be clear or colorless. Usually, there are 6-8 vertical bars on the sides, which may or may not be prominent. The gill cover (operculum) peaks into a broad, round flap that is black in color; however, it is not surrounded by a lighter colored trim as it is in some other sunfishes. It has the small mouth and head that are typical of sunfish species. The pectoral fins are pointed.
