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.
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). Many species are sought by anglers as popular panfishes , and large numbers are bred and stocked in lakes , rivers , ponds and wetlands .
Fish, like these yellowfin tuna, use many different mechanisms to propel themselves through water. Fish locomotion is the various types of animal locomotion used by fish, principally by swimming.
[4] [5] [6] Lepomis megalotis can be distinguished from closely related dollar sunfish L. marginatus by a greater number of cheek scale rows, by having one to two additional pectoral fin rays and by the slope of the opercular flap, which is distinctly upward in L. marginatus but is closer to horizontal in males of L. megalotis, although female ...

The nature of prey selection by two centrarchids (white crappie and bluegill) has been presented as a model incorporating optimal foraging strategies by Manatunge and Asaeda. [23] The visual field of the foraging fish as represented by the reactive distance was analysed in detail to estimate the number of prey encounters per search bout.
Pumpkinseeds are very similar to the larger bluegill, and are often found in the same habitats. One difference between the two species is their opercular flap, which is black in both species but the pumpkinseed has a crimson spot in the shape of a half moon on the back portion. Pumpkinseeds have seven or eight vertical, irregular bands on their ...
Fish gills are organs that allow fish to breathe underwater. Most fish exchange gases like oxygen and carbon dioxide using gills that are protected under gill covers (operculum) on both sides of the pharynx (throat).
