Physical characteristics
Deep, laterally compressed body with a disc-like shape. Coloration is vibrantly mottled with orange, green, yellow, and blue spots. Features a distinctive small black opercular (ear) flap with a prominent red or orange crescent-shaped spot on the posterior edge. Possesses a small mouth reaching only to the front of the eye.
Habitat & distribution
Native to northeastern North America but widely introduced elsewhere. Prefers clear, quiet lakes, crystalline ponds, and slow-moving streams with abundant aquatic vegetation and submerged logs for cover.
Behavior
Diurnal and highly social, often found in loose aggregations or schools, especially when young. Adults are known to be territorial during the breeding season. They stay close to submerged structures and weed beds.
Diet
An opportunistic feeder that consumes aquatic insects, larvae, small mollusks (snails), crustaceans, and occasionally very small fish or fish eggs.
Reproduction
External spawners where males excavate shallow, circular nests in colony groups on sandy or gravelly bottoms. Males guard the eggs and newly hatched fry aggressively against predators.
Ecological role
Functions as both a secondary consumer and prey. It helps control populations of aquatic insects and snails. Smaller individuals serve as a vital food source for larger predatory fish like Largemouth Bass and Northern Pike.
Similar species
Bluegill (Lepomis macrochirus) which lacks the red spot on the ear flap and has a dark blotch at the base of the dorsal fin; Longear Sunfish (Lepomis megalotis) which has a much longer ear flap.
Identification tips
Look for the bright red or orange 'half-moon' spot on the edge of the black ear flap and the iridescent blue wavy lines on the cheek and gill cover.
Interesting facts
They possess specialized pharyngeal teeth (throat teeth) that are hard and pavement-like, allowing them to easily crush the shells of snails and small crustaceans.
