زيست شناسي     واژه نامه (بعنوان مثال epibenthic)

Inhabits silty, sandy, or rubble bottoms (Ref. 9710). Feeds on fishes (Ref. 13628). Possesses electric organs located in a specialized pouch behind the eyes. Can discharge up to 50 volts (Ref. 10576).The electric organ discharge (EOD) rate depends on the temperature: about 500 Hz at 35°C and 50 Hz at 15°C (corresponding to the annual temperature range of the habitat of this species) (Ref. 10011). Cleithral spine with venom gland (Ref. 57406).
