  3.  @allan2765  Here's the way I see it (and I admit It's all guess work). A GW is a big predatory fish (I do have a fair bit of experience getting smaller predatory fish to bite on things). I have observed that, a predatory fish has two methods of feeding: it scavenges around looking for dead/injured meat and it attacks certain moving prey. When a fish attacks, its brain is triggered and it uses all energy to injure/kill/eat the prey. This is an instinctive behaviour that the fish has little thinking control over. This is exampled by the many artificial lures made of metal that look nothing like fish. There is footage of GWs attacking a basic seal shape lure which doesn't much resemble any seal. I think it probably goes something like this: GWs have feeding areas where they head for when they are hungry: there's no humans in these areas - so no problems. When a GW is around where humans are swimming, GW is probably digesting a seal carcass and does not get triggered to attack. Occasionally, GW is ready to feed and encounters human in distance. The human gives off various stimuli which are sufficiently 'seal like' to trigger the GW's brain to go into 'attack mode'. Bang! in seconds the person is hit - the GW now either recognises human is not usual prey and backs off - or continues in instinctive feeding frenzy. The problem is having made the mistake the GW's orange sized brain is able to learn that, humans are a potential prey animal. I think the idea that GWs see humans as food, cannot be so. If this was the case humans would never be in the water where GWs are around - it would be the equivalent of hundreds of seals floating with blindfolds on. The GWs would soon be on them.
