Population: Unknown They generate a shock of 500 watts (500 volts and 1 ampere) on average They can shock up to 700 watts Human beings die at as little as 0.75 ampere
Can control the intensity of their shocks Eels can be used to generate electricity for human purposes In Japan, two eels in a tank were used to light up a Christmas tree Eels are very hostile and will kill and animal it is with besides another of its own species
