Great white goes the distance

Several research projects, including one from Stanford University, have been studying the movements of great white sharks, and their travel schedule appears to be exhausting.

Researchers tracked a great white shark and watched her log more than twelve thousand miles swimming from Africa to Australia and back. It’s the first proof of a link between the two continents’ shark populations.

A second report details the movement of dozens of salmon sharks from summer waters near Alaska to warmer winter quarters off Hawaii and Baja California.

Barbara A. Block of Stanford University says the findings – which appear in Friday’s issue of the journal Science – shows that the conservation management of sharks such as the white shark and salmon shark will require international cooperation.
