FIGURE 10. Characterization of the electric organ discharges of Gymnotus carapo australis and Gymnotus cuia. A. Head-totail recorded EOD waveforms for Gymnotus carapo australis (black) and Gymnotus cuia (red) from Rio Grande do Sul, Brazil. Note the invariable presence of the P-1 and P3 phases in the waveform in G. carapo australis but not G. cuia. B. Power spectral density (PSD) plots for Gymnotus carapo australis (black) and Gymnotus cuia (red) from Rio Grande do Sul, Brazil. Note the higher peak power frequency in G. carapo australis.Published as part of Craig, Jack M., Malabarba, Luiz R., Crampton, William G.
