According to Dial Global The Living Planet Aquarium in Utah is using  Treean electric eel to power the lights on a Christmas tree in its “Journey To South America” gallery. Terry Smith, project manager at Cache Valley Electric, said the electricity generated by an eel in a nearby tank causes the four strands of lights on the 5-foot tree to flash intermittently at the Sandy aquarium. Officials at the aquarium said electric eels can discharge specialized cells called electrocytes simultaneously to create a 600-volt electric charge equal to about five times the power of a standard U.S. wall socket. The eel-powered tree will be on display through December 31st.
