Shark Takes A Chunk Out Of Rival. Must See!!!

This incredible footage of a Shark on shark attack was captured during my diving at Neptune Islands, South Australia. This video shows unbelievably rare behaviour in Great White Sharks and has not been captured previously. This video is unique because neither shark has been influenced by bait. Some of you may have viewed other footage of shark on shark attacks but these are purely accidental incidences because the two sharks strike at the bait line and inadvertently hit each other. I hope people find this video interesting and it contributes to understanding the complex behaviours of this wonderful and important species. Thanks for watching.
