E. nana displays predator avoidance responses relying on chemical cues from its native predators, such as Micropterus salmoides. Antipredator responses include freezing behavior to its fish predators. Site tenacity, the pattern of returning to the same nest or breeding site dependent on the season, was observed in both males and females of E. nana.
