A woman who was attacked by a shark in Southern California was all smiles in a photograph taken as she recovers from a large bite wound that stretches from her shoulder to her pelvis.

The photo taken Thursday and provided by Orange County Global Medical Center on Monday shows Maria Korcsmaros, 52, grinning in her hospital bed, wearing a gown with a cast covering nearly the entire length of her right arm.

Korcsmaros — a mom and triathlete — was expected to recover from the bite she received May 29 at Corona Del Mar State Beach, doctors said. The shark that attacked her was not found.

The large single bite she suffered suggests the shark was over 10 feet long and most likely a great white, said Chris Lowe, director of the Shark Lab at California State University, Long Beach.

Meanwhile, authorities reopened a 2-mile stretch of Sunset Beach and Surfside Beach that shut down after several sharks were spotted Sunday off the coast.

A sheriff's helicopter crew saw the sharks off Sunset Beach in the city of Huntington Beach. The animals were estimated to be at least 8 feet long and 150 yards from shore.

Closures following a shark sighting typically last between 12 to 24 hours.
