Christi:
From what I know about diving around Coz, you are much more likely (don't get me wrong, it is not a common site at all) to see Bull sharks around Playa de Carmen than Coz. After all, what does a big shark really have to eat around a reef, most of the fish are pretty small, (someone is thinking "people" right now) so it is not an environment that supports big predators feeding on a regular basis.
I have read the books (there are actually more than 1) on the events of 1916? at Matawhatever creek. I don't believe that the remains found in the "great white" caught were ever truelly confirmed as those of any of the victims. I don't think that the main medical investigators got a look at it, but I could be wrong on that. There was definitely some conjecture that they scapegoated the shark to ease public fear and bolster the hurting NJ tourist industry. There is still a lot of conjecture, which I would tend to agree more with, that it was a big bull shark, not a great white, due to the lack of salinity, as far up the creek as the shark travelled and the length of time a white shark could survive, let alone have "feeding" be its primary evolutional drive, when it is dying from its own biological cells bursting. The bull shark theory makes more sense.
