SciShow Explores the World of Animals That Sense and Produce Electricity

In the latest episode of SciShow, host Hank Green explores the world of electric animals. The category includes animals with electroreception, the ability to detect electric currents to get a better idea of their surroundings, and those with electrogenesis like the electric eel, which can produce their own electric current for hunting and self-defense.

Biologists believe that electrogenesis has evolved separately at least 11 separate times, in places as isolated from each other as the African interior, the Amazon basin and the coral basin in Australia.
