Two young boys surfing off California's Manhattan Beach had the shock of their lives when they peered at a photo taken by their mum's digital camera.
According to news reports, June Emerson had snapped the picture of her 12-year-old Quinn and his friend watching a towering wave nearby.
Within the body of water just metres away however, a large dark shape with fins can be seen just under the surface.
Most believe the shape is that of a large shark.
Both boys had exited the water unharmed, and ignorant of the creature that had come so close to them to investigate.
