Two New Species of Electric Knifefishes Discovered in Central Amazon

These species – Brachyhypopomus bennetti and Brachyhypopomus walteri – are weakly electric relatives of South America’s famous electric eel (Electrophorus electricus) that can produce strong electric discharges of up to 600 volts.

By contrast, the new species produce pulses of only a few hundred millivolts from an organ under the body that extends out onto a filamentous tail.
