Ecological Role - The green sunfish is a benthic organism, meaning that it lives and feeds near the bottom of the water. It is an opportunistic insectivore and piscivore in that it feeds on whatever insects and smaller fish are nearby. Its mouth size allows it to consume larger food items than other members of the sunfish group. Its ability to adapt to environmental extremes in temperature, dissolved oxygen, turbidity, and water flow allows it to be a pioneer species, or one of the first species to occupy a stream. When the water in a stream gets low, the green sunfish may be the only species surviving in a small isolated pool. It repopulates once the stream flows again.

Fun Facts - The green sunfish is a native species that is found in almost any aquatic habitat in Kentucky. It readily hybridizes (crossbreeds) with other sunfishes, especially bluegill and longear sunfish. Green sunfish-bluegill hybrids are commonly sold as "hybrid bluegill" The green sunfish is also called black perch, green perch, and pond perch.

Food - Adults: aquatic and terrestrial insects, crayfish, other fish; young: small crustaceans, aquatic insect larvae
