Largemouth Bass
Micropterus salmoides
Key differences: Largemouth bass have a more elongated body, a much larger mouth extending well past the eye, and a dorsal fin that is almost completely divided into two distinct parts (spinous and soft-rayed). Sacramento Perch have a deeper body and a single, deeply notched dorsal fin.

Green Sunfish
Lepomis cyanellus
Key differences: Green sunfish have a larger mouth than bluegill but still smaller than Sacramento Perch, and often exhibit iridescent blue-green spots on their operculum and body. They also possess a distinct black opercular spot with a pale margin. Sacramento Perch lack these iridescent markings and the distinct opercular spot.
