A California mom thought the photo she snapped of her son and his friend sitting on surfboards with a breaking wave at their backs was a normal amount of cool — until she noticed the two boys were being photobombed by a shark.

"It was quite a shock to see," June Emerson told KTLA.

The photo was taken last Friday at Manhattan Beach, where Emerson and her son Quinn often hang out. Not wanting to scare the boy into buying a bigger surfboard, Emerson told a little (great?) white lie.

"I told my kids it was dolphin," she said, "as we live at the beach and are in the waters here almost daily."

According to a recent LA Times article, great white shark sightings near Manhattan Beach are on the rise, which is actually a good thing, and a sign that the ban on gill nets put in place in 1990 is leading to a "healthy rebound for marine life."
