Beachgoers at Ancon Beach in Marbella were left scrambling after a huge fish appeared to follow a swimmer through the shallow water. The creature was initially mistaken for a shark, sparking panic among onlookers, before it was identified as an injured tuna weighing around 660lbs. People eventually used sunbeds and deck chairs to help guide the struggling fish back toward deeper water. #spain #news #viral #shark #tuna
