I've learn about it here : https://www.independent.co.uk/news/s...-10381295.html.

Some scientists have discovered that death metal music do attracts great white sharks. It's not only a fun story it's also very useful to them as it does give them a way to study the great white sharks or attracts them without a bait which is a more environnemental friendly and animal rights careful method to be near to the great white sharks even though the music atttracts them because it sounds to them like struggling fish and make them wants to be near what might be a great new meal in their mouths. The similarity between death metal sound and struggling fish sound to a great white shark ear they explain is due to both having a similar low rumbling frequency. Off course their for scientists using this method to attract the great white sharks needs to protect themselves from the hungry sharks but they know how to do it therefore to my knowledge none of them using this method for study great white sharks as ever been hurt. Off course i would never recommand that method to someone not a shark specialist who knows how to protect themselves doing so but i'm happy to share knowledge here about people going imaginative to find better ecological methods to study marine life. I had always suspected great white sharks to be hardcore metalheads anyway (last sentence just joking), lol.
