 An alert beachgoer captured a shark swimming off Navar beach in Florida's Panhandle. Cell phone video released July 4 showed the telltale fin and outline of the shark as some bathers took notice and headed for the safety of the beach while others remained in the surf. The shark appeared again briefly on the video and then appeared to move on. A rash of US shark attacks have been reported this summer, including in the Northeast. According to the website Tracking Sharks, through early June, at least 16 such attacks were reported in the US, 9 of them in Florida and none that were fatal.
