I have been obsessed with great white sharks since I saw Jaws when I was a very small child. I have seen the movie 'Twelve Days of Terror' and read the book as well, and both are utterly fascinating. Like it was said in the book, this incident in 1916 was a 'once in a lifetime' deal. Nothing like this has ever been happened before (and if it did, it was NEVER documented) and probably will not ever happen again, at least not in our lifetimes. I whole heartedly believe that the culprit back in 1916 was a juvenile great white shark. There are scientists that believe it was a bull shark, or a group of sharks. The shark that is on the cover of 'Twelve Days of Terror' was later autopsied and 10 to 15 pounds of human flesh were found inside. There is no doubt that it was a real, true man-eater that attacked all of those people (I believe it was 6 people total, and only one survived.) A shark that preys on humans (which is not a natural food source for sharks of any species) truly, in my opinion is a freak of nature. Very fascinating.
