What started as a carefree day at Carrum Beach in Melbourne turned eerie after a family photo revealed something chilling. A father and his young daughter were smiling in the clear water, enjoying the sun — but when they looked closer later that night, they noticed a dark, fin-like shape rising just behind them.The photo, taken in 2023, seemed ordinary at first. Yet after being posted online, it spread rapidly across social media, stirring debate and fear. Some believed it showed a shark lurking nearby, while others dismissed it as a trick of light or reflection.
