Electrogenic fish, of which there about 250 species, possess a specialized organ that can generate very high voltages when
needed for protection or to stun prey. Proper equipment such as rubber-soled shoes and rubber gloves provides some protection
against shock when handling these animals. Additionally, these animals can be agitated, causing them to produce
a series of shocks leading to electrical discharge, which makes them safer to handle. Examples of electrogenic fishes
include electric eels (Electrophoridae), knifefish (Notopteridae), and catfish (Malapteruridae) in freshwater and electric
rays (Torpedinidae) in saltwater.
