Ambloplites rupestris, commonly known as rock bass, is a freshwater fish species native to North America. While the scientific name is unique to this particular species, there are a few common names used interchangably to refer to the rock bass. These synonyms include the red eye bass, shaded bass, goggle-eye, and the rock perch. These names are derived from the distinctive red eyes and patterned markings on the fish's body. Despite its name, the rock bass is not actually a bass, but rather a member of the sunfish family. Rock bass are popular among anglers for their excellent game qualities and can be found in small streams and lakes throughout the United States.
