Electric (torpedo) rays (Torpediniformes) have large electric organs (electroplaques) on either side of the gill arches derived from branchial musculature that can produce moderate electric discharges (Shuttleworth 2012). Skates (Rajiformes) can produce weak electric discharges from small bilateral electric organs in the tail (Smeets et al. 2012). Both groups are capable of intermittent and focused discharges (Sisneros and Tricas 2002). As with teleosts capable of electric discharges, the co‐ordination of this discharge originates in the medulla (Sisneros and Tricas 2002; Smeets et al. 2012). The relatively low amplitude of 20–40 mV from skates contrasts with 30–60 V from electric rays (Sisneros and Tricas 2002).
