Life History and Behavior

Behavior

Electric Organ Discharge

The EOD waveform of Marcusenius monteiri has a total duration of 0.35-0.45 milliseconds and is triphasic with a weak head-negative prepulse (P0) followed by a head-positive phase characterized by a slow initial rise and abrupt inflection point, followed by a head-negative spike. Usually the "overshoot" fourth phase is absent or very small.
