Shark Attack Surge in North Carolina: What Could Be Behind It

Experts see several possible factors that may be contributing to the problems.

There have been 11 shark attacks off the shores of the Carolinas this year, most in just the last three weeks.

On Wednesday, a 68-year-old man was bitten by a shark off the coast of Ocracoke Island, North Carolina. The victim, identified by the hospital as Andrew Costello, was bitten on his left side in his lower leg and hip and on both his hands, Hyde County EMS Director Justin Gibbs told ABC News.

“They do like the clear ocean water,” said Capt. Steve Wilson of Dream Girl Sport Fishing, “but you also have a booming sea turtle population and they love sea turtles.”

Though some are calling for beach closures, North Carolina Gov. Pat McCrory is offering a warning instead.

“Recognize that there are certain areas where we are having these bites,” he said. “So use your common sense -- especially if you are in and around a fishing area.”

Shark encounters haven’t just been limited to the Carolina coast.

An aggressive shark capsized a man's kayak in Florida in a terrifying moment caught on video last Thursday.

Ben Chancey, a U.S. Coast Guard captain for fishing charters, was off the coast of Stuart, Florida, trying to catch a goliath grouper when several bull sharks started swimming around his kayak, he said.
