Electrophorus electricus, commonly known as the electric eel, is a species of knifefish found in the freshwater rivers and swamps of the Amazon and Orinoco basins in South America. Despite its name, it is not a true eel but a type of fish that can grow up to 3 meters (10 feet) in length. This fish is famous for its ability to generate electric shocks, which it uses for hunting and self-defense. It has specialized cells called electrocytes that produce electricity, allowing it to deliver shocks of up to 600 volts.
