Electric Eel (Electrophorus electricus)

Origin: South America
Sighted at: Dallas World Aquarium, Dallas, TX

The electric eel is known around around the world for its ability to generate electric shocks against both prey and would-be predators. But many people don’t know there are many other fish that can generate electric fields of varying strengths – nearly four-hundred other species of fish from around the world, in fact!

The electric eel is also not an eel at all – rather, it’s a species of knifefish, which are all long, slender South American freshwater fish that are capable of electric field use – although not all knifefish use electricity to hunt, as the electric eel does. They instead use it for navigation – or possibly even communication!
