 Over the Fourth of July weekend, six people were attacked by sharks, two of which were in Florida and the other four in Texas. In June, a shark bit a teen in shallow water at North Topsail Beach. UNC shark expert Joel Faudre tells NCN News. I will say that I think a lot of the bites that we see, that's because people are in the surf zone, certainly. But that surf zone is a very turbulent, noisy, chaotic environment. Sharks are highly evolved, and then really they try to avoid risk.
