 It's been a rash of shark attacks in Atlantic waters this season and the list continues to grow. Authorities say a man bitten by a shark over the weekend on Florida's northeast coast is recovering. Officials from the Nassau County Sheriff's Office north of Jacksonville found the victim aboard a boat on Friday with a severe shark bite on his arm. The victim is still in the hospital. His name has not been released. It was the third shark attack in Florida in June. An expert warns that more shark activity is to be expected.
