The electric eel.

An electric eel (Electrophorus electricus) is a fascinating species of fish native to the Amazon and Orinoco River basins in South America. Despite its name, the electric eel is not a true eel but rather a type of knifefish. It is capable of generating powerful electric discharges, which it uses for hunting, self-defense, and navigation.

The electric eel can produce electrical voltages of up to 600 volts using specialized cells called electrocytes. These cells are organized in electroplaques and are capable of discharging electricity in a controlled manner. The electric shocks are strong enough to stun prey like fish, making it easier for the eel to catch them. They also use these electrical discharges to communicate and detect objects in their environment, similar to echolocation.

Electric eels can grow to lengths of up to 8 feet (2.5 meters) and are an interesting subject of study in both biology and bioelectricity. Despite their remarkable abilities, electric eels are not considered dangerous to humans, though their shocks can cause significant discomfort or even temporary paralysis if not carefu
