This photo of surfers and friend was taken at "Swamis Beach."
The image claims to show a shark swimming under a wave
next to surfers at the beach in Encinitas, California.
Lifeguards say it's a surfer doing a manuever called a duck dive, where a surfer dives under an approaching wave. A shark expert says it looks like a great white shark. Sharks have been spotted nearby. Could it be a hoax? Or it it mistaken identity?
Is it a shark or a surfer?
