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 state of New Jersey in the United States owns and administers over 354,000 acres (1,430 km 2) of land designated as "Wildlife Management Areas" (abbreviated as "WMA") throughout the state. These areas are managed by the New Jersey Division of Fish and Wildlife, an agency in the New Jersey Department of Environmental Protection. [1]

[ 11 ] [ 12 ] It is a highly prized sport fish among anglers for their vigorous resistance when caught, and have been introduced to many regions due to their popularity in bass fishing and tolerance to urban streams .
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.
A betta fish's lifespan can be impacted by the care it receives, WebMD reports. Bettas may live longer if their tank is clean, the environment is calm and their diet is healthy.
Aristotle (ca. 340 B.C.) may have been the first scientist to speculate on the use of hard parts of fishes to determine age, stating in Historica Animalium that “the age of a scaly fish may be told by the size and hardness of its scales.” [4] However, it was not until the development of the microscope that more detailed studies were performed on the structure of scales.
