TED-ED: How do fish make electricity? - Eleanor Nelsen

The video explores the fascinating world of electric fish, which use electricity for communication, navigation, and hunting. It distinguishes between weakly and strongly electric fish, explaining how they generate electrical signals. Weakly electric fish use low voltage for sensing their environment, while strongly electric fish, like the electric eel, use high voltage to hunt prey. The video also touches on the mystery of why these fish don't electrocute themselves, a question that remains unanswered by science.
