FIGURE 3 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 3. Petrocephalus binotatus of the Lékoli River system of Odzala National Park, Republic of the Congo. A. Photograph of a live specimen (no scale: the photo has been maximally enlarged to better illustrate details of body shape, melanin patterning, etc.). B. Photograph of a preserved specimen (scale bar = 1.0 cm). C. EOD waveforms displayed separately for obvious males and other individuals (see text). One EOD was arbitrarily selected from each recorded individual and superimposed with the other recordings (N = number of individuals, given separately for obvious males and all other individuals). All EODs are scaled to the same peak-to-peak voltage, and they are plotted (head-positive up) on the same time scale as overlays centered on the largest positive peak of each waveform (scale bar = 0.2 msec).
