The Dorsal Fin

In what appears to be a promotional video of some kind for Omega watches, professional golfer Greg Norman (aka The Great White Shark) was filmed cage diving with white sharks (Carcharodon carcharias) off Australia’s Neptune islands. Norman is sponsored by the watch company as an “Omega Ambassador.”

Another “Shark Week” promo from DiscoveryNetworks focuses on the very first shark cage and how Rodney Fox pioneered the act of cage diving. Fox who survived a white shark attack in 1963 came up with the idea of the shark cage when he decided that he wanted to get back in the water after recovering from the attack. His cage design helped to revolutionize white shark photography and videography.

From YouTube user davidwlitchfield comes a video featuring a white shark (Carcharodon carcharias) getting briefly stuck in the lower opening of a surface cage. After bumping into the boat, the shark quickly turns and gets his nose in between the bars of the cage. The diver in the cage is able to push the shark back using his camera allowing the shark to freely swim away.

The video description doesn’t indicate where this encounter took place, but given the time of year (assuming the video was shot recently) and the visibility, my guess would be South Australia.

DiscoveryNetworks YouTube channel offers up a preview clip of the upcoming show “Jaws Comes Home” which features footage shot around the carcass of whale which several blue sharks (Prionace glauca), as well as an an 18′ female white shark (Carcharodon carcharias), have come to feed on.

Researcher Greg Skomal and cameraman Nick Caloyianis take the opportunity to film/photograph the encounter from a cage, which is being supported by buoys. After taking an interest in the orange buoys supporting the cage (which the narrator dramatically describes as “attacking”), the white shark becomes trapped between the surface and the top of the cage.

While situations involving wild animals will always have a level of unpredictability, hopefully the engineers behind this particular cage design/setup will take this event into consideration with future designs.

YouTube user mvanh80 recently added the video above, which features a predation event of great white shark (Carcharodon carcharias) on a petrel (a seabird). The video, according to its description on YouTube, was shot on July 9th, at South Australia’s Neptune Islands, which is a popular great white shark diving hotspot.

While I’ve seen plenty of footage of tiger sharks (Galeocerdo cuvier) preying on seabirds, I think this is the first bit of footage that I’ve encountered which features a white shark feeding on a bird.
