New Smyrna is the shark attack capital of the world, and it was here that three swimmers were attacked this year, and had to be hospitalized. In the beach's home county of Volusia, six other attacks had been recorded by March, 2008. That breaks the record pace set in 2001, according to beach records, making this the "Year of the Shark." . The International Shark Attack File cites a total of 210 attacks in Volusia, Fla. Still, miles of white sand and consistent surf breaks continue to draw vacationers and locals alike into New Smyrna's waters.

Number two on the International Shark Attack File for unprovoked attacks is Oahu, where tiger sharks, Galapagos sharks and sandbar sharks congregate in high numbers, especially near beaches on the island's north shore. This doesn't stop surfers, who flock to Velzyland Beach, the Leftovers Break and dozens of additional wave-beaten beaches where sharks search and swim.

Thanks in large part to Jaws, great white sharks inspire unparalleled fear when it comes to swimming in the ocean. At Bolinas Beach, a secluded town with a namesake beach that's just north of San Francisco, 15-foot-long beasts and known to dwell under the waves where surfers play.

In the past 100 years, there have been 90 reported shark confrontations on beaches in this county on Florida's east coast. Visitors head east from Orlando to the ocean to dip toes in the tepid waters at Cocoa Beach, Jetty Park and Klondike Beach, a 24-mile-long wilderness beach accessible only by foot in Canaveral National Seashore preserve.

The deep blue water of Kahana Beach, near its namesake town on the west cost of Maui, is home to sea turtles, humpback whales and… tiger sharks. Laleh Mohajerani, executive director of the shark conservation organization Iemanya Oceanica, says the massive predators swim near the protective offshore reef that makes the beach a popular swimming spot.

Though it didn't happen at a beach, the death of an Austrian lawyer who was diving with sharks in February off the Bahamas has focused attention on these tropical waters. Patric Douglas, owner of Shark Diver, an ocean guiding outfit in San Francisco, says they're "among the shark-iest places on the planet." He's personally seen 14-foot-long tiger sharks off the beaches where millions of tourists swim and sunbathe each year.

In the shadow of Marin County's Mt. Tamalpais, great white sharks come to swim in the shallows of Stinson Beach. Patric Douglas has sighted them at this beach—which is a neighboring stretch of sand eastward of Bolinas Beach (also on this list, in the number three spot)—in less than 20 feet of water. "They're coming to feed on seals, though it's not uncommon for surfers to see them," he says.

The International Shark Attack File reports three unprovoked attacks in the waters off Baja California Sur over the past decades. But the beaches of La Paz—a harbor city of 190,000 people—are relatively safe, despite the hammerheads and giant whale sharks that swim nearby. The latter is a filter feeder that's the largest fish species on Earth, and a resident of these waters.

Peter Benchley's original 1974 novel, "Jaws," was inspired by incidents at this New Jersey beach in 1916. In an unprecedented 11 days, five major shark attacks took place along the Jersey Shore, four of which were fatal. Reports cited blood turning the water red and sharks following victims toward the beach. Today, shark sightings are rare, but the legend lives on in the surf and swells of these tepid Atlantic waters.
