When scuba diving in the ocean waters, you might want to make sure your underwater radio isn't playing AC/DC music lest you attract some unwanted predators. Apparently a recent not-so-scientific study by a South Australian tour operator Matt Waller has revealed by trial and error that the great white shark is quite fond of AC/DC's lower frequency rock sound, especially "Shook Me All Night Long" and "If You Want Blood." No doubt the great whites are quite interested in blood so the song definitely fits!

According to the news agency <a href="http://www.adelaidenow.com.au/shark-tours-put-ac-in-deep-sea/story-e6frea6u-1226066785052"><span style="color: #0000ff;">Adelaide Now</span></a>, " Mr. Waller discovered the unusual attraction for sharks when taking tourists out on his swim with great white sharks trips.  'We know the AC/DC music works best by trial and error, and we are doing more research to see what works best with different species of shark,' he says."

During Matt Waller's research he discovered that sharks actually hear better at lower frequencies, usually between 20-1,000 hertz. That is seriously low when compared with humans, as well as man's best friend. For your comparison, humans are able to hear 20-20,000 hertz, while your family dog, depending on the breed, is able to hear from 40-60,000 hertz.

The importance of Waller's finding? He is trying to lure the sharks to his tours so that his paying customers can get up close and personal for a "thrill." The way sharks search for food is two ways...scent and sound, which is where AC/DC comes into play. Waller and his company, Adventure Bay Charters, intends to use the music to trick the sharks into thinking they have found dinner. It sounds as if his usual customer prefers to stay on his ship, while the occasional person prefers to go into the cage to be dropped into the water to get truly close up and personal with the shark. As strange as it sounds, you might actually safer in the cage than on the boat. While sharks don't usually jump into boats, of all the varieties of shark, the <a href="http://www.rescuediver.org/rescue-tech/sharks.htm"><span style="color: #0000ff;">great white</span></a> seems to be the one that actually does this more than all of the others.

Personally, I am not a fan of any of these tour companies that lure animals like this for a cheap thrill. If you happen to see a shark when out and about, great, how exciting, but why not leave them be? Why do we have this compulsion to mess with nature all of the time just so we can say we saw a shark, or swam with the dolphins, etc. etc.?
