Killer Sea Turtle?

I thought that i should post a picture of the sea turtles we spent so much time trying to find.  I believe that this particular picture was captured after this turtle, in the opinion of my wife, tried to disembowel her.  While catie and i were swimming back to the boat that took us to a point known as "Turtle Town", catie began to grab and claw at me as if Jaws himself was approaching.  At that moment, i suppressed the urge to scream like a woman and looked at what i could only assume would be a man eating beast.  To my surprise, what i beheld was a very slow moving, large sea turtle.  I took many photos, but it is pretty hard to be precise with an underwater camera.  John, Catie, Jessica, and I were fortunate enough to see many of these calm animals on our trip, certainly for me one of the highlights of our trip to Hawaii.
