Have you seen our electric eel tank? Electric eels are not really eels, but members of the knife fish family. Their bodies contain about 6,000 special cells that store power like batteries. They can emit a burst of at least 600 volts, which is 5 times the power of an electric wall socket.
Electric eels live in muddy waters in South America. They are mostly blind, and rely on their electric power to explore their surroundings, kill prey, and to protect them from predators.
