The "e" in E-tree stands for two things: eco and electric eel!

In order to raise public awareness for the power-producing capabilities of electric eels, a Japanese aquarium Aqua Toto Gifu, built the E-tree. A conductive copper wire was inserted inside the tank where the slimy zapping sea creature resided, while the other end of the wire was attached to the colored lights of a nearby Christmas tree. When the eel slithered against the wire, the eel's currents would cause the ornaments to light up.
