I had the oppertunity to watch them document these bizzare feeding techniques on tv. It was awesome watching those sharks fly out of the water like that after slamming the fake seals they put out. That seal island is one dangerous place. What was real cool was they had placed a camera in one of the fake seals they were dragging around and one of the sharks demolished it. One crazy guy got ontop of a dead decomposing whale that great whites were chomping on and was literally within touching distance of the feeding sharks. They are awesome creatures.
