“…First, in pulse gymnotiforms, the self-generated electric field polarizing the nearby objects in the near environment has a different waveform depending upon object location relative to the body Caputi et al, 1989Caputi et al, , 1994Caputi et al, , 1998aCastelló et al, 2009;Rodríguez-Cattáneo et al, 2008, 2013Stoddard et al, 1999;Waddell et al, 2016). The site-specific waveform is due to the different weight of the different waveforms emitted by the different regions of the electric organ (Caputi et al, 1989(Caputi et al, , 1994(Caputi et al, , 1998aRodríguez-Cattáneo et al, 2008, 2013Castelló et al, 2009;Sanguinetti-Scheck et al, 2011;Pedraja et al, 2014;Waddell et al, 2016).…”
