The enormous 2.5 metre eel has been named the Electrophorus voltai after Alessandro Volta, the Italian physicist who invented the battery.
The animal, a type of knifefish, can discharge an electric shock reaching as high as 860 volts, the most powerful of any animal known to science.
The research by a team from the São Paulo Research Foundation, comprising scientists from the Smithsonian Institute and National Geographic Society, also revealed a further distinct species of electric eel – bringing the planet’s recognised electric eel species up from one, to three.
“It’s quite literally shocking, when you discover new diversity in such an eye-catching fish first described 250 years ago,” lead author of the research paper, Carlos David de Santana, from the US National Museum of Natural History told the New York Times.
