In a fascinating turn of events, researchers from NOAA Fisheries were stunned when a sandbar shark caught off the coast of South Carolina was revealed to have been previously tagged exactly 12 years prior in nearly the same location. This rare find occurred 30 miles offshore from the bustling tourist destination of Myrtle Beach, shedding new light on the behavior of these elusive creatures.
A Surprising Discovery
The sandbar shark, measuring 5 feet, 5 inches, is part of a species known for its seasonal migrations between nursery grounds and offshore areas. NOAA Fisheries research biologist Michelle Passerotti noted the unusual nature of this recapture. “Sandbars are not typically known for site-specific behavior beyond females returning to nursery areas to pup,” Passerotti explained. “This finding raises the intriguing possibility of some sharks exhibiting more site fidelity than previously thought.”
The Bigger Picture
This recapture was part of the 2024 Coastal Shark Bottom Longline Survey, an extensive effort that spans from southern Florida to the Outer Banks of North Carolina. This year alone, the survey tagged 1,949 sharks, contributing to the more than 10,700 sharks tagged over the program’s 35-year history. Remarkably, only about 271 sharks have been recaptured, highlighting the rarity of this event.
Diverse Shark Population
During the 2024 survey, dusky sharks were the most frequently caught species, followed by tiger sharks, blacktips, and scalloped hammerheads. Among the recaptures were nine sharks (seven sandbar and two dusky sharks) that had been previously tagged, including one tagged 24 years ago off Georgia.
The Life of a Sandbar Shark
The sandbar shark recaptured near Myrtle Beach is estimated to be between 25 and 30 years old and likely has given birth multiple times. Sandbar sharks are among the largest species found in coastal waters, reaching up to 8 feet in length and weighing around 200 pounds. Despite their size, they pose little threat to humans due to their preference for smaller prey and tendency to avoid beaches.
What This Means for Shark Research
This remarkable recapture has opened new questions about the behavior of sandbar sharks and their potential site fidelity. While it’s unclear whether this was a mere coincidence or indicative of a broader behavioral pattern, it underscores the importance of long-term tracking and research in understanding marine life.

Myrtle Beach Shark Bites
In the past 10 years, Myrtle Beach has seen a relatively low number of shark bites, with a total of 11 incidents reported. This includes multiple bites in some years, such as 2022, when two bites occurred on the same day. Despite the presence of various shark species in the waters off South Carolina, these incidents remain rare and typically result in non-fatal injuries.
The shark species most commonly involved in these incidents include blacktip sharks, tiger sharks, and sandbar sharks, which are frequent in the coastal waters of South Carolina. While shark bites can be alarming, they are exceedingly rare given the large number of people who swim in these waters each year.
To minimize the risk of shark encounters, experts recommend avoiding swimming during dawn or dusk when sharks are more active, steering clear of schools of fish, and not swimming near fishing areas where bait might attract sharks. Despite these precautions, the likelihood of a shark bite remains very low.
