They swim silently beneath the surface, unseen and unnerving. Sharks have long been a symbol of fear, danger and mystery.

Although it is very rare to be bitten by a shark – a 1-in-3.7 million chance – the concern about shark attacks continues.

According to the International Shark Attack File (ISAF), which is maintained by the Florida Museum of Natural History , the U.S. is the leading country in the world for the number of unprovoked shark bites, with at least 1,660 reported since the 1800s.

So far this year, there have been 12 shark attacks in the U.S., with seven incidents taking place in Florida.

And Florida is not alone. Certain states, like California and Hawaii , have seen more encounters between humans and sharks than anywhere else in the country.
