No seals were around during this. Just bait. Captured on a GoPro was a shark catching on to some bait. The short clip is truly some unbelievable footage. Experts want people to know that the sounds being made are not from the shark, but rather the GoPro rubbing on the metal cage it is in on.

According to GrindTV.com:

Dan Abbott, a spokesman for White Shark Africa, said the footage was captured at Seal Island.

 

Abbott said there were six divers in the cage at the time, and that the breaching shark caught everyone by surprise because there were no seals or decoys near the cage.
