So fresh fish AND an affinity for Australian hard rock are some things I have in common with Bruce from Finding Nemo.
From the article:
According to a report from Adelaide Now, shark tour operator Matt Waller discovered the fish-friendlier alternative to chum, saying music is even more effective at luring great white sharks than ground-up fish. He consulted shark experts and found that the animals are most attracted to sounds within a specific frequency -- and one band seems to strike the right chord.
Another article says the low frequencies in AC/DC's music is a similar practice to the Polynesian practice of rattling coconut shells to attract sharks. I think most agree that the video below is a bit nicer to listen to than this.
For good measure, lets attract some sharks (Volume up)
