The Marine Science Institute's monthly column, Science and the SeaTM, is an informative and entertaining article that explains many interesting features of the marine environment and the creatures that live there. Science and the SeaTM articles appear monthly in one of Texas' most widely read fishing magazines, Texas Saltwater Fishing, the Port Aransas South Jetty newspaper, the newsletter of the Texas Chapter of the American Shore & Beach Preservation Association , and the Heartland Of America online newspaper. Our article archive is available also on our website.
Most people know that electricity and water don’t mix, but it’s not a problem for fish that produce their own electricity. The best-known electric fish is probably the electric eel, but it is far from the only “shocking” creature underwater. In fact, the electric eel, a single species that dwells only in the rivers of South America, is outnumbered by more than 60 species of electric rays that live in the oceans.
