Electric Organ Discharge:

EOD unknown. The electric organ has electrocytes with penetrating stalks with anterior innervation (Type Pa) in which the stalk penetrations are large. From the anatomy one would expect this species to have a triphasic discharge with a significant initial head-negative phase, P0, to the waveform.
