Beachgoers at Marbella on Spain's Costa del Sol fled the water in a panic after spotting a fin cutting through the waves, fearing a shark was nearby. The creature causing the commotion turned out to be a tuna rather than a predator, and no one was harmed in the scare.

Sightings of large fish or dolphins are occasionally mistaken for sharks at popular Spanish beaches, prompting brief evacuations before lifeguards or officials confirm there is no danger. Details of the exact date, the number of swimmers involved and any official response from local authorities were not provided in the available report.
