Electric eel

Electric eel (Electrophorus electricus), eellike species of fish of the family Electrophoridae that can produce an electric discharge, found in northern South America. Electricity, generated by electric organs composed of modified muscle cells or electroplaques, is used to detect and stun prey, repel enemies, and communicate with other electric eels. These long, narrow fish can grow to 8 ft (2.4 m), are colored olive brown, and can produce 350–650 volts of electricity.
