Now to the questions circling around a photo that's gone viral.
We showed it to you Monday. A snapshot taken by a California mom named June Emerson.
She was at the beach Friday with her twin boys when she says she saw a shark in the water.

Was it a shark?
Was it a dolphin?
Was the photo actually doctored?
Brett Larson, the host of TechBytes, says he's on the fence about the authenticity of the picture but he's leaning towards the opinion that it's real.
"We've seen sharks and other animals that swim at that point in the water," he says.
