Neither are particularly likely to go you unless 1) provoked 2) unable to source less threatening food source
Cage diving off Port Lincoln saw 4 great whites, two of which came and rattled the cage. Strange thing is, they only took a half doz tuna carcasses over the 10 hours we were out there. They really were after the 4000 baby seals that were just born near by. The crew were trawling the tuna heads etc whilst standing up on the bait boxes with no safety gear - best guess is the sharks wouldn't have had a go.
Why would they go something as large as a human when plenty of food sources less confronting....?
My only point, as an SSI Scuba Instructor, is that the behavior is dangerous and ill-advised. I could, theoretically, stand in the middle of the Interstate and not be hit by a truck. I don't think I am going to take the chance to see if that happens or not.
If some commercial fisherman wishes to tempt fate by standing on a bait box, in a rolling sea with sharks all around, best of luck to him should he misstep and fall into the drink.
Marine life is untamed, and therefore, unpredictable.
A good example would be Siegfried and Roy. The lion/tiger that bit Roy had been domesticated for 20+ years and still damn near killed him.
I guess the only point I'm trying to make is that the danger is not really commensurate with what popular opinion has it.
I've been on many many dives with smaller (6-8") sharks, even during feeding frenzy, and they're just not interested in attacking something similar to their own size.
What's the whole SSI thing like? I'm a PADI divemaster, but never crossed over to SSI - tho it is getting more popular down under
We have had several deaths from great whites in the so cal area over the past 4 years. I am in the ocean swimming and paddling on a weekly basis, and often more than mile offshore. I am in greater danger starting up my car and driving, than being killed by a shark. Life has inherent risks.
