Tim Handsel, the director of Husbandry at Ripley's Aquarium, said that while it's too far away to make a positive identification, it appears to be a Blacktip shark or Spinner shark. Both of these are coastal sharks that are common to the Carolina coast, and are frequently caught by both surf and pier anglers. The majority of the adult Blacktip and Spinner sharks found in our waters are about 5 to 6 feet in length, Handsel said.
