A group of scientists have tried to install loudspeakers on dead coral reefs of Australia's Great Barrier Reef to get fishes to swim back by repeating the sounds made by healthy reefs, counteracting the damage done to many of the world's coral reefs today. /VCG Photo

Compared to previously, the number of fishes that came and stayed has doubled as a result of the sound played. /VCG Photo

The University of Exeter marine biologist Tim Gordon pointed out that the return of the fishes help in bringing back a healthy ecosystem to the corals. /VCG Photo

According to CNN News, the Great Barrier Reef experienced several large "bleaching" incidents in the past decades due to rising water temperatures. /VCG Photo
