The organ surrounding the body of an electric catfish can stun prey or be used in defense by discharging up to 350 volts of electricity.

"Africa's freshwater electric catfish (Malapterurus electricus) can discharge up to 350 volts from an electric organ surrounding its body. Like the electric eel, it uses this high-voltage jolt to stun prey as well as to deter would-be attackers. Interestingly, this species is also very sensitive to the Earth's magnetic field. In captivity, it responds to magnetic currents generated several hours before an impending earthquake." (Shuker 2001: 53)
