Spatiotemporal distribution patterns of immature Australasian white sharks (Carcharodon carcharias)
Abstract In Australian and New Zealand waters, current knowledge on white shark ( Carcharodon carcharias ) movement ecology is based on individual tracking studies using relatively small numbers of tags. These studies describe a species that occupies highly variable and complex habitats. However, un...
