So one of the popular very fascinating dives in Cabo Pulmo is a 100 ft dive off Frailis Pt to see big tiger sharks. I have not done that dive but
have heard about it and I would love to do it. Good chance the bites were taken after he drown but possibly not. You may not know there is a
population of Great White sharks in the Sea of Cortez. Big ones.

Has anyone seen a follow-up report on this? Wondering if he died of a shark attack, or if the injury was postmortem.

What's that I hear? bump-bump-bump-bump-----------bump-bump-bump-bump-sounds like a movie lead in :-)
Actually, many decades ago, study was done on divers and wet suits. They showed that an all black wet suit "could/would" get bit but if it was black
and wide white striped the beasties wouldn't bother it. Don't know what ever became of that study (maybe 50 years ago). Paint the bottom of your surf
board black and white stripes!

Cliffy, there is a Ted Talks episode from western Australia, maybe five years ago, that showed this to be true.
They filmed a black wetsuit filled with chum being torn apart and consumed in no time.
They then filmed a black and white striped wetsuit filled with oozing chum and not one of the local species would get closer than several feet before
turning away. Great whites, bulls, tigers, bronze whalers all reacted the same way.
It was mind blowing to see that none of them would come any closer to that tasty blood and guts filled suit.
This is because of the structure of sharks vision, rods and cones, that for some reason, causes them to be repelled by this black and white striped
pattern.
It is fascinating to to watch. I should go back and watch it again and refresh my memory, but the impression it left upon me is enduring.
After Bethany lost her arm in Hawaii, I started seeing the bottom of surfboards with this pattern in the Islands. Little wonder. I can't hurt.
I have since thought surfers, ocean swimmers and divers could benefit from wearing striped suits of some sort. As natural a shark repellant as there
is.
It would interesting to see if further studies have been done and whether the men in the gray suits have ever overcome their initial reticence to
charge on in on the black and white striped chum filled suits.
Thanks to all here.

That is very interesting. Maybe the black and white thing has to do with shark meat being on the Orca menu?

The documentary I watched about the black and white thing speculated that it was the same pattern as the very venomous sea snake that sharks avoid big
time.
sold out and got out !!!

World wide, many attacks are by bull sharks that travel far upriver in fresh water that has just a couple of inches visibility.
I doubt that the black and white pattern would be much help in those rivers, even if you could convince the swimmers that they needed to wear
something other than trunks!
If you are not living on the edge, you are taking up too much space!
"Could do better if he tried!" Report card comments from most of my grade school teachers. Sadly, still true!

It might limit the amount of damage if the bull shark saw the strips even after clamping down.
That's interesting about the AU study. The one I remembered is at least 50 yrs old. It was back when I was surfing in my teens. Yes, that long ago :-)
