Research Indicates Sharks Can Detect Magnetic Fields
- "Sharks on migration swim arrow-straight lines across featureless ocean basins. How they navigate over such great distances has been a mystery. Now experiments by scientists at the University of Hawaii demonstrate that sharks are able to detect magnetic field changes, supporting theories that the predators can map their location by deciphering differences in Earth's magnetic field lines." - excerpt from the article at http://www.enn.com/today.html?id=631
