Great white sharks 'personality' revealed

World first research into great white shark behaviour in local waters is bringing fascinating new insights, as well as new warnings, to the surface. Kathryn Ryan talks to the University of Guelph's Steve Crawford, who is studying their conservation and management. Thanks to his research there is now greater understanding around their individual 'personalities' courtship and mating behaviour, plus a hypothesis that great whites may be acutely aware of, and responsive to, the female human scent.
