Electric Catfish

Granted that the electric catfish is not an absolutely dynamic fish, spending much of its time lying on the bottom, it can give a painful shock to a human; producing a charge of about 350 volts.

While an electrical shock from one of these catfish will not be powerful enough to kill a human, it is strong enough to stun prey. This is significant resulting from the fact that the aforementioned catfish are not equipped to swim swiftly and so prey might effectively break from them.
