Sharks act calmer when listening to AC/DC!

This strange discovery was made by Matt Waller, a tour operator in Australia’s Neptune Bay. Despite the fact that they have no ears, the sharks’ favorite two heavy metal tunes were “You Shook Me All Night Long” and “Back in Black”. When Waller played these songs using underwater speakers, the Great Whites became “more investigative, more inquisitive, and a lot less aggressive.” It is not known for sure why hammerheads tend to be metalheads, but Waller believes it has something to do with the songs fitting a certain frequency and vibration in the water that the sharks must like. This sort of finding could revolutionize cage-diving procedures by using music instead of bait to lure in sharks during tours!
