My Farallon Islands Adventure

Well to all my peeps, in less than a month I will be going on a "Great White Adventure" and visit the Farallon Islands. This is an unheard-of island that is near Fisherman's Wharf in San Francisco and it is notorious for having HUNDREDS of Great White Sharks visit there during the months of September-November. It is an alcove of huge, jagged rocks and the Great White Sharks (only species of shark known to go there) enjoy a vast amount of their favorite prey...seals. It is also said that this is where they mate, but no one has actually seen a Great White Shark mate before, so no one can say for sure. In the disclaimer that I had to sign for this trip, it mentioned that I need to be prepared to see Great Whites attacking and killing seals, and to realize that it is a violent, gruesome, bloody death. THAT's the only part that I am worried about on my three-day trip. I can't watch nature shows or Planet Earth documentarys because I will BURST INTO TEARS when I see an animal in pain and being eaten. So I think, if that happens in front of me, I'm gonna have to go to the other side of the boat :) I'll take lots of pictures and video. One question though that has been on my mind as November 4th comes closer, is do sharks make any kind of noise? Like when they burst out of the water with their enormous jaws open, is there a roar, or a growl, or any kind of noise that comes out???? What do you think?
