GAINESVILLE, Fla. (AP) - An annual shark attack study reported the number of shark attacks increased worldwide in 2010 while declining in Florida for the fourth straight year.

According to the University of Florida's International Shark File, released Monday, the state recorded 13 incidents last year. That's well below the yearly average of 23 attacks over the past decade.

Ichthyologist George Burgess, director of the file housed at the Florida Museum of Natural History in Gainesville, says Florida typically tops the list in shark attacks.

There were 36 shark attacks in the United States last year, including five in North Carolina and four each in California, Hawaii and South Carolina.

Worldwide, 79 shark attacks were reported in 2010, the highest number since 2000. There were six shark fatalities worldwide.
