Using genetic studies, scientists reveal how these exotic creatures develop their unique electricity-generating organs that can unleash a wicked jolt.
As astonishing as the bioluminescence found in some insects and sea creatures and echolocation in bats and whales, the wonder of nature that is the electric fish has long fascinated scientists and nature lovers alike. They are the only animals so far that have been found with the ability to zap others.
Hundreds of species of electric fish exist worldwide and they are divided into six main groups: South American knife fishes, African electric catfish, African elephant fish, stargazers, some skates and some rays. And though we have known of their existence for a long time, the mechanism behind their ability to generate electricity has never been fully understood until now.
