Chris Hasson's 10-year-old son Eden was surfing Tuesday when a shark appeared lurking beneath the wave, a moment Hasson caught on camera.
"It was a chance encounter, a one in a million photo," Hasson said.
Hasson and some others were on the beach at Samurai Beach in the Australian town of Port Stephens. As he was taking pictures, he saw something out of the corner of his eye as his son was about to ride a wave.
Hasson then took a series of shots, and when he went back to look at them, sure enough he saw the shark.
"I was very concerned," he said, so he called to his son and the other surfers to come ashore.
Then he showed them the shot, which they loved.
"Everyone was high-fiving after they saw the photo," Hasson said.
Eden even responded with a joke: "Lucky I didn't fall off."
