The bluegill sunfish relies heavily on the flexibility of its fins to maintain maneuverability in response to fluid forces. The bluegill's segmentation in its pectoral fin rays mitigates the effects of fluid forces on the fish's movement. [19] The bluegill has a variety of unusual adaptations that allow it to navigate different environments.

Common names of fish can refer to a single species; to an entire group of species, such as a genus or family; or to multiple unrelated species or groups. Ambiguous common names are accompanied by their possible meanings. Scientific names for individual species and higher taxa are included in parentheses.
The generic name Lepomis derives from the Greek λεπίς ("scale") and πῶμα ("cover", "plug", "operculum"). The genus' most recognizable species is perhaps the bluegill. Some Lepomis species can grow to a maximum overall length of 41 cm (16 in), though most average around 10–20 cm (3.9–7.9 in).
Centrarchidae, better known as sunfishes, is a family of freshwater ray-finned fish belonging to the order Centrarchiformes, native only to North America.There are eight universally included genera within the centrarchid family: Lepomis (true sunfishes), Micropterus (black basses), Pomoxis (), Enneacanthus (banded sunfishes), Centrarchus (type genus, consisting solely of the flier C ...
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.

It is black and often has a white margin. The pectoral fin is relatively short and would not reach the snout if it were reflected anteriorly. In breeding males, iridescent blue spots develop on the dorsum and sides and the fin membranes turn orange in all fins except the ventral ones, which may be blue to black, [ 4 ] and the pectoral ones.
