Electric Eel

It’s positively shocking: An electric eel (Electrophorus electricus) can produce an electric charge of up to about 600 volts – five times the voltage of a wall socket, and strong enough to injure a human.

Located in the tail, the eel’s electric organs serve several uses. Low-intensity impulses help eels communicate and navigate, while high-intensity charges stun or kill prey, and provide a defense.
