Most electric fish

The electric eel (Electrophorus electricus) , is an electric fish, and the only species of the genus Electrophorus. It is capable of generating powerful electric shocks, which it uses for both hunting and self - defense. It is an apex predator in its South American range. Despite its name it is not an eel but rather a knife fish.

Up to 1.8m (6 ft) in length, the fish is live from head to tail with its electrical apparatus consisting of two pairs of longitudinal organs. The shock which can measure up to 650 volts is used to immobilize prey and is strong enough to light an electric bulb or to stun an adult human.
