Muir. We begin with what is shaping up to be the summer of the shark along one stretch of Atlanta ocean shore. A new attack in North Carolina today, and on the map you can see the cluster of 7 attacks, the latest in okra coke on the outer banks. As we head into the biggest beach weekend of the year, every one of those spots expected to be crowded with swimmers. Here's ABC's Melvin Gordon. Reporter: Tonight another victim air lifted after a mauling at sea. Officials say the man in his 60s attacked by a shark, all while swimming in waist deep water. His hip, leg and hands injured. It's the 7th attack in the last three weeks on North Carolina's shores, including two children, a boy and a girl, each losing limbs in separate incidents last month. When I saw him, his arms went up, the shark took his left arm. And he just took off running. He started screaming is this real, is this real. All of a sudden I saw a fin. Reporter: Over the weekend this man felt a similar set of jaws. It took a pretty big chunk out of my legs. Reporter: He was also in waist deep water but decided to fight back. I started punching the shark and then it grabbed my back. Must have bitten me in the back. Reporter: He saw his 8-year-old son frozen with fear in the shallows. I ran over and grabbed jack and as I was bringing him to shore the shack came again and bit me in the back. This time he bit me really, really hard. Reporter: Tonight these breach remain open. We asked the governor if he would order them closed. His office tells ABC news it's up to the various local officials to decide. So far, no decision to close the beaches. Experts advise to do whatever you can to fight back. You got to strike them. Quick, fast, punch down. Reporter: Given all the people expected in the Carolinas for the 4th of July weekend, Amy, shark experts tell us expect another victim. Now, what can you do to protect yourself? Avoid wearing anything reflective, staying in shallow water and avoid these jetties and piers. Fishermen use bait and bait attract sharks.
