Out of water, however, an electric fish may be more susceptible to its own power. Jason Gallant, a zoologist at Michigan State University, has heard that electric eels spasm when pulled from the water. That’s probably because their charge doesn’t readily dissipate through air. Instead, it travels across the fish’s wet skin, delivering a more concentrated shock. Also, Gallant’s team found that several groups of electric fish express the same genes, which encode structural proteins that could insulate their electric organs.
