Communication and Perception
Longear sunfish exhibit a number of behavioral display postures that are probably used in communication such as when the male the turns on his side and displays his bright orange ventral surface, frontal display (orienting toward another fish and erection of the opercula and accompanied by sigmoid bending of the body), biting, courtship circling, and so on. Male longear sunfish are also known to make a distinctive grunting sound during courtship and spawning.
