Torpedo fish, or electric rays, are fish capable of producing an electric discharge, or electric shock, to stun prey or for defence. They produce around 220 volts of electricity – enough to stun or kill and adult human.
Torpedo fish have enlarged pectoral fins that house electric organs either side of the head. These are made of modified muscle tissue and are controlled by the electric lobe in the brain. Four central nerves branch repeatedly from the electric lobe to control the electric organ.
