Nearly 350 species of fish have specialized anatomical structures that generate and detect electrical signals. Underwater, where light is scarce, electrical signals offer ways to communicate, navigate, find, and sometimes stun prey. But how do these fish produce electricity? And why? Eleanor Nelsen illuminates the science behind electric fish. [Directed by Franco Barroeta Fonseca, narrated by Julianna Zarzycki, music by Christopher Bullé-Goyri].
