Electric organ discharge (EOD) diversity and electric organ anatomy in Paramormyrops. EOD traces from specimens in this study and representative parasagittal sections of the five Paramormyrops operational taxonomic units (OTUs) considered in this study. 200x magnification on P. kingsleyae EODs reveals a P0 phase on triphasic EODs only. Individuals with triphasic EODs all have penetrations, whereas individuals with biphasic EODs do not. OTUs with ‘inverted’ polarity triphasic EODs have large penetrations compared to OTUs with normal polarity triphasic EODs. Ant. = anterior, C = connective tissue septa, N = nerve, NPp = non-penetrating, posteriorly innervated stalks, M = microstalklets (profusely branched stalks), P = penetrations, Pa = penetrating, anteriorly innervated stalks, Post. = posterior, S = stalks. Image from P. kingsleyae biphasic originally appeared in reference 43
