Fig. 12. (A) Schematics of the electrogenic system in the adult fish [modified from Caputi (Caputi, 1999)]. The activation of the electric organs (EO) in the biphasic larvae (B), in the triphasic larvae (C) and in juveniles and adults (D) is indicated in a schematic based on the adult electrogenic system. Arrows of different colors indicate the different waveform components that are progressively added in the course of postnatal development.
