You're at the beach, taking pictures of your kids playing in the water. When you get home, you notice something strange in one of the photos. Swimming beside your kids is a shark. It happened at Manhattan Beach in California.

June Emerson told KTLA, her 12 year old son Quinn and his friend were in front of wave with their surfboards.  After seeing the photo she told her kids it was 'a dolphin' but locals who have seen the picture believe it was a shark.

Emerson and her family live near the beach and are in the water almost every day. I think I'd find a new place to swim.  SCARY!
