For each individual, the collection locality and specimen number are provided. For each specimen, one column of the entire electric organ was surveyed for the specified depth (μm) from lateral to medial (see Fig. 9). Total number of electrocytes, and the number of those exhibiting Pa type morphology and NPp type morphology are provided. Finally, the assessment of the overall EO morphology is specified as either Pa (>75% of electrocytes Pa) NPp (>75% electrocytes NPp) or mixed (<75% of electrocytes of one type). Note that some individuals determined to have Pa anatomy did not have penetrations in the rostral or caudal portion of the organ (See Fig. 9). In these cases, electrocytes could not be fully surveyed because of the orientation of tissue during sectioning.
