 "My son is the one closest to the shark," June Emmerson told NBC4.  "Whatever it is, it was quite a shock to see while reviewing shots of the day on our way home."

Was it a shark?

"Discovery Channel shark expert Jeff Kurr calls it a great white shark, but shark expert David Shiffman believes it was a dolphin," according to CNN.

According to shark expert Randy Hamilton, CNN reports, juvenile sharks eat fish in southern California and then move north to cooler waters, near San Francisco, and begin to feed on mammals -- sea lions and seals.
