Want to confuse a shark? Use a magnet - Salon

Even more peculiarly, sharks seem to be able to sense minute changes in Earth's magnetic field, amounting to a sort of "sixth sense" for magnetism. .

The study, published in the journal "Cell Biology," found that sharks use the Earth's magnetic field to navigate Earth's oceans, a feat made easier by the fact that every spot on this planet has its own distinctive magnetic signature.

The discovery will aid marine biologists in understanding the inner working of this group of elasmobranchii, the subclass of animals that includes not only sharks but also sawfish, rays and skates?
