No one wants to go to a boring party. If you’re looking for an exciting time, you wouldn’t go to a library, you go where the music is playing. Well turns out that fish feel the same way. In a strange but pretty neat experiment, scientists played healthy reef sounds in dead coral and the fish flocked to it.
We, humans I mean, tend to think of underwater as quiet because we can’t hear anything but to the creatures who live down there, it’s as a loud place to be. Unless of course the space has been killed off. In order to attract sea life back to dead coral, they played audio of living coral reefs. Twice as many fish showed up than what had been coming to the quiet dead spots.
This technique can help to revive coral reefs that have been damaged by a variety of issues. By bringing new life into the area, it will help to revitalize the space but is not silver bullet to the problem. Large populations of fish help but they won’t undo the damage that humanity has done.
