A group of young lads camping on the shores of a small lake suddenly missed a member in the middle of the night.
After searching in the dark for several hours he could not be found so they called the police.
Next morning divers found the body of the boy.
Police suspect he was drowned after a discharge from a huge electric fish.
Fish that have an EOD that is powerful enough to stun their prey are called strongly electric fish.
The amplitude of the signal can range from 10 to 500 Volts with a current of up to 1 Ampere.
Typical examples are the electric eel (Electrophorus electricus; not a true eel but a knifefish), the electric catfishes (family Malapteruridae), and electric rays (order Torpediniformes).
