Several sharks were spotted swimming off of the coast of Myrtle Beach before noon Tuesday near 63rd Avenue North.
A yellow caution flag was staked at a lifeguard station nearby. Lifeguards were advising swimmers to stay out of the surf as the sharks headed south, chasing a school of bluefin tuna, the guards said.
Near 14th Avenue Pier, the coast seemed clear, as beachgoers enjoyed swimming and playing in the surf with no fins in sight several minutes later. An angler on the pier, however, did snag a young shark he soon set free.
A man was bitten on the foot by what he thought may have been a shark around 12th Avenue South in the Myrtle Beach surf Monday afternoon. The man was treated on scene.
Never miss a local story.
There have been numerous reports this year of two great white sharks swimming along the Grand Strand, but those sharks typically swim in deeper waters, miles offshore. But nibbles from smaller sharks can and do happen near the coast.
To avoid sharks, marine experts advise beachgoers to avoid swimming during dawn and dusk, when sharks are more active, or when the water is particularly murky.
