Some interesting thoughts banging around in my head (I'm land locked here in Utah waiting for months before my next dive - thinking and not diving, a sure formula for random data review). I consider that bulls bite more people than any other species of sharks - as reported in modern times, due in very large part to the overlap of bull shark and people habitat - along beaches. I know that Oceanic white tips live in generally baren open waters and if they get a chance to eat something - well, I don't think they have much compunction about humans (see jaws, ok that is a bit scary, using Jaws as a factual reference) given what happened with the Indanappolis. Now perhaps more than usual you have the opportunistic oceanic white tips interacting with humans. Not a great equation for success but then the reality is that such crossing over of territory has been going on there since man first started diving in the Red Sea, just got an anomoly going on right now. I have not changed my attitude toward diving with sharks which is, bring them on, great photo opp, except for the big 4. Great whites, tigers, bulls, and oceanic white tips. Those guys are on my "calmly surface and carefully get the hell out of the water list. After finishing my dive of course.
Crowley, those were great posts.
