An eel cage was an underwater torture device in which four electric eels were restrained by a set of binders to create a restraining device. The prisoner was placed inside the cage, and the electricity created by the eels prevented them from leaving. If the interrogator forced one of the eels inward, it struck the prisoner and sent a painful electric charge surging through them.
During the Battle of Mon Cala on Dac in the Clone Wars, Riff Tamson used this device to torture Jedi Knights Kit Fisto and Anakin Skywalker in an attempt to discover the whereabouts of the Mon Calamari prince, Lee-Char.
Behind the scenes
The eel cage first appeared in the Star Wars: The Clone Wars episode "Prisoners". Although not identified by name during that episode, they were described by the name "eel cage" on concept art that appeared on the official StarWars.com website after the episode first broadcast.
