The longear sunfish (Lepomis megalotis) is a species of freshwater fish in the sunfish family (family Centrarchidae) of order Perciformes. It is native to the an area of eastern North America stretching from the Great Lakes down to northeastern Mexico.
The longear sunfish reaches a maximum recorded length of about 24 cm (9.5 in), with a maximum recorded weight of 790 g (1.7 lb).
While L. megalotis is readily caught by anglers, the fish are typically too small to be useful as food, and most anglers release them.
The genus Lepomis has a well-characterized mating behavior where parental care is done by the male. He makes and defends the nest.
Trade in the longear sunfish is restricted in Germany because of the potential for environmental damage caused by introduced sunfish species.
