There have been some outstanding animal photobombs throughout 2013.
But the following may take the dangerous cake.
During a recent trip to California's Manhattan Beach, June Emerson snapped a picture of her 12-year old son and his friend on a boogie board… with an unexpected guest popping up in the background to say hello.
See for yourself:
Fortunately, that's all the shark said, as Emerson confirms neither child was harmed during their play time at sea.
"It was quite a shock to see," June told KTLA. "Many local surfers and lifeguards have seen this and believe it to be a shark ... Of course, I told my kids it was dolphin, as we live at the beach and are in the waters here almost daily."
Probably a good call. And this remains only the second scariest photobomb of the year, trailing this shot of a shirtless dude strolling in front of a wedding party.
