Newsflash: There are sharks in the sea, swimming around like they own the place.

It shouldn't come as too much of a surprise that a spear fisherman, in South Africa of all places, might encounter some very large, very predatory fish. And yet despite knowing all this, what does strike the humble viewer is the almost-choreographed theatric entrance of a great white.

Just remember kids, it ain't the size of your spear gun, it's the speed which you beat a retreat to surface and shout 'White! White!' that counts.
