Over the last few years, there have been shark attacks off a California state-run beach near where we live. The most recent attack involved a 27-year-old surfer, in October of last year. Thankfully, the attacks were not fatal.
Of course if you stay out of the water, your shark attack chances are zero. But for those who love spending time and activities in the ocean, and have a fear of sharks, this post lists statistics and information that should allay your shark attack fears.
Background, from the Ichthyology Department, Florida Museum of Natural History:
Of the over 375 different species of sharks found in the world’s oceans, only about 30 have been reported to ever attack a human. Of these, only about a dozen should be considered particularly dangerous when encountered. The shark species responsible for most unprovoked attacks on humans are the white (Carcharodon carcharias), tiger (Galeocerdo cuvier), and bull (Carcharhinus leucas). All sharks, large and small, are however predators and could be capable of inflicting wounds if provoked. They should all be treated with respect when encountered.
The chances of being attacked by a shark are very small compared to other animal attacks, natural disasters, and ocean-side dangers. Many more people drown in the ocean every year than are bitten by sharks. The few attacks that occur every year are an excellent indication that sharks do not feed on humans and that most attacks are simply due to mistaken identity.

And in case you have not yet heard — at least here in the U.S. — you are more likely to get hit and killed by lightning, than attacked and killed by a shark.
In the last 50 years, there were 1,970 lightning fatalities, compared to 26 shark attack fatalities (out of 974 known shark attacks). I hope that makes you less afraid of being attacked by a shark while playing in the ocean. After all, that is over 50 years of data!
Details are listed on the table below.
NOTES: California, Florida and Hawaii have the longest saltwater shorelines — and California and Florida are among the most populous states in the U.S.— so it makes sense that there are more attacks (and fatalities) for these states.
Florida’s coastline is 1,350 miles (2,170 km), California is 840 miles (1,350 km), Hawaii is at 750 miles (1210 km), based on large-scale nautical charts.

So did it work? I know I am less afraid of sharks and shark attacks, now that I have some facts. How about you?
