Shark Bait video

The sequence to the right was shot by Rick Allen, of Nautilus Productions. 

It shows a young but battle-scarred White Shark making an investigatory pass at the bait secured at the stern of our research vessel in False Bay, South Africa.  The shark then seems to become confused by the electromagnetic field generated by the port-side outboard motor and gives it a tentative, exploratory 'nip'. 

Before we understood that sharks are sensitive to such invisible cues, such nips were interpreted as aggressive or indiscriminate.  We now know better.
