You're at the beach with your 12-year-old and his friend.
Everyone's having a lovely time, so you take out your phone or some other device and snap a picture of the happy moment.
When you look at it later, you see there's something in the background. Yes, that long thing in the water.
Is that a fish? Wait, is that a baby great white shark?
This seems to have been the sequence of events described by mom June Emerson of her oceanside visit to Manhattan Beach, Calif.
As KTLA-TV reports, Emerson's son Quinn and his friend were having a surfing good time.
When she looked at the photo, however, she experienced a "shock."
She told KTLA-TV: "Many local surfers and lifeguards have seen this and believe it to be a shark."
Did the kids freak when she told them? Well, almost. She said: "Of course, I told my kids it was a dolphin, as we live at the beach and are in the waters here almost daily."
Of course, I have a feeling the kids watch TV -- even if they don't, they must have heard that mom's shot was on the local news -- and they now know that it might have been a shark. So the subterfuge may not have been entirely effective there.
Apparently, great white shark sightings aren't entirely rare in the area. However, I didn't study enough (any) biology to know whether this is, indeed, a little great white one or a dolphin doing its morning yoga.
It seems that all sorts of creatures can invade modern photography. Why, only the other day, a ghost.
So please examine your photographs as you're taking them. Just in case the people you're shooting are about to get spooked or eaten.
