A collaborative shark tagging programme between NIWA, the Department of Conservation and US scientists is generating some surprising findings.
Four great whites tagged in southern waters were monitored for nine months, after which their tags floated to the service and sent an email, via satellite, to the scientists. The email reports the temperature, depth and location of the shark for those nine months.
Amelia meets with Malcolm Francis and Michael Manning at a NIWA laboratory to talk about the findings and gets a first hand lesson in shark anatomy.
