FIGURE 6 in African weakly electric fishes of the genus Petrocephalus (Osteoglossomorpha: Mormyridae) of Odzala National Park, Republic of the Congo (Lékoli River, Congo River basin) with description of five new species

FIGURE 6. Petrocephalus balayi of the Lékoli River system of Odzala National Park, Republic of the Congo. A. Photograph of a live specimen (no scale). B. Photograph of a preserved specimen (scale bar = 1.0 cm). C. EOD waveforms. One EOD was arbitrarily selected from each of two recorded individuals, and they were superimposed together. Both EODs are scaled to the same peak-to-peak voltage, and they are plotted (head-positive up) on the same time scale as an overlay centered on the largest positive peak (scale bar = 0.2 msec).
