Electric Organ Discharge Frequency Modulations Evoked in Response to Jamming Stimuli in the Weakly Electric Brown Ghost Knifefish (Apteronotus Leptorynchus)
Gymnotiform electric fish emit a weak electric organ discharge (EOD) for the purpose of electrolocation. Although individual fish emit at unique EOD frequencies, they can actively modulate the frequency of their EODs during social interactions with conspecifics. Gradual frequency shifts occur …

The contribution of the pectoral fins, body, and the ribbon fin to turning maneuvers of a gymnotiform swimmer
… investigated the weakly electric Black ghost knifefish (<em>Apteronotus albifrons</em>: Apteronotidae) with an atypical control surface, namely a ribbon fin. To investigate how a fish with an atypical control surface performs turning maneuvers, <em>A. albifrons</em> was filmed performing small …
