BiologyAffinities: P. pellegrini. Generates electric organ discharge (EOD) of short duration that seems to correlate with aggregative behavior of the species (Ref. 14060; 10601). EOD temporal pattern cues have been shown to play a role in species recognition for P. bovei (Ref. 10600). A ratio measure between olfactory and visual receptor areas suggests that this species relies more on visual than olfactory information (Ref. 10839). A fractional spawner (Ref. 10605; 10606).
