Mr Nerhus described great whites as perfectly designed killing machines towards which he holds no animosity.“I realise it obviously mistook me at first for its natural prey, which would have been possibly a seal," he said."I couldn't think of a worse way to go than to end up as fish food. And that's why I fought back, because I was determined I didn't want to go like that. It's a very undignified way to go. I like my life too much.”
