Shark Sniffs Photographer's Camera

Filmmaker Dave Riggs is getting ready for the Discovery Channel's Shark Week (auto-start video). While getting footage off the coast of South Australia, a 13.5 foot long female Great White Shark approached him. Curious, she examined him. Discovery News quotes Riggs:

“Of course, great whites don’t have hands, so she was researching the area in the only way she knows how -– and that’s with her mouth,” Riggs said.

So when a Great White Shark mouths you, it's like a dog smelling you. Try to be friendly in response.
