Immediately after the female leaves, the male begins to fan the nest with his paired and caudal fins. He will fan the nest up to an hour after the spawning event. ranking system or pecking order among members of a long-term social group, where dominance status affects access to resources or mates, animals which must use heat acquired from the environment and behavioral adaptations to regulate body temperature, fertilization takes place outside the female's body. Adapted from Page and Burr (2011). The males are less responsive to non-threatening fish like topminnows (family Fundulidae).

The longear sunfish is a small, thin, deep bodied fish that averages ... covers, which are flexible with frilled margins. The authors stated that areas with more vegetation may be harder to maneuver in and make escape from predators more difficult. Hybridization in sunfish occurs more readily when: (a) one species greatly out-numbers the other, (b) breeding areas are crowded, or of poor quality, and (c) two populations come in contact when they have not been previously. While their diversity is greatest in the southeastern USA (my friend in Louisiana collected 8 species in the lake behind his house! Nearly always found in shallow water, preferring habitats with dense vegetation in small lakes, ponds and slow moving rivers and streams. Compared to other members of the sunfish family Centrarchidae, longear sunfish are better at obtaining food in moving waters than still waters. Cheeks orange with wavy blue streaks radiating back from the mouth and eye. The central longear, L. m. peltastes, is generally larger and has a longer opercular flap at a 45° angle, posterior end higher. The longear sunfish populations are stable. They range in size from the rather large redear sunfish down to the tiny orangespotted sunfish.

Male digs nest and defends territory during prespawning period. That family includes several similar but distinct species such as the Bluegill, various types of bass, and multiple sunfish such as the Green Sunfish, Redear Sunfish, Longear Sunfish, and more. Longear Sunfish (Lepomis megalotis), listed as Threatened in Wisconsin, prefers clear, shallow, moderately warm, still waters of streams and occasionally in lakes.

If moved from their home range, they will quickly return, apparently through the use of smell. Goddard and Mathis (2000) also performed experiments where they artificially manipulated the lengths of male flaps. The satellite male is similar in age and appearance to the sneaker male, but instead of dashing into the nest, he will hover over a nest, acting the part of a non-threatening female, and slowly descend into the nest containing a courting pair of sunfish and, like the sneaker, release sperm during the spawning event.
