This was the highest number in a decade, amounting to an increase of 25 percent on 2009, when there were 63 attacks with six fatalities, and 49 percent over 2008, which had 53 recorded attacks, four of them mortal.
So far this year, there have been six deaths and seven cases of injuries, according to an unofficial toll compiled by AFP from news reports.
Compared to deaths from smoking, road accidents, lightning strikes or even from other animals, the risk is minute, say experts.
"The attention from shark attacks is completely overblown," said Agathe Lefranc, a scientist with a French group, the Association for the Study and Conservation of Salachians (APECS), a category that includes sharks and rays.
Marine biologists say there is little research into the causes of shark attacks but point to several possibilities, all linked to humans themselves.
No. 1 is quite simply the growth in mobility, with cheap air travel and package vacations enabling people to swim, snorkel, surf or dive in places that previously had no human presence.
