Is an electric eel really electric?

Yes. Electric eels will attack humans when they feel threatened, and their shock of 600 volts is powerful enough to kill a horse. Electric eels can grow as long as 8 ft from head to tail end, and weigh up to 45 pounds. Attacks from electric eels are very rare in humans, but researches have said that a shock from an electric eel can cause heart or respiratory failure and drowning in shallow water.
