According to Carolina Beach Today a family who caught a “shark encounter” on video are still trying to identify the shark that passed close by them on September 14. A mother and her three children are seen playing in the shallows when the shark passed by. While there is never really a good clear shot of the shark, after strategically pausing the video around 30 seconds and getting a decent look at the dorsal and caudal fins, I’m going to throw my guess out there as the species being a sandbar shark, which are commonly found in the area. I’ve also got a vote for a blacktip shark, which are also common in the area.
UPDATE: I was able to pull the following frames from the video that show the dorsal and caudal fins.
