Ever caught a shark? Jacob Langston did last week. But he had no idea until he left the beach.

The Orlando Sentinel photographer was taking some video of a surfer off New Smyrna Beach in Florida when he heard another surfer scream, "Dude! Did you see that?"

Langston didn't. But his camera did: a four-foot spinner shark had just hurtled over an unwitting surfer.

Check it out, and notice the surfer's body language screaming, "Whoa."

How do we know it's a shark?

"They are pretty common at the inlet," says Langston, who was in the water at the time. "People get photos of them all the time jumping out of the water. The surfers knew immediately what it was."

Spinners don't pose a threat to humans, as their teeth are made for munching small fish rather than big mammals.

But this one definitely left a mark.
