PORT-SAINT-PERE, France, Sept. 29 (UPI) -- Dolphins are sensitive to the presence of magnets, say researchers in France. It's the first study to definitively prove that dolphins are magnetosensitive, or magnetoreceptive.
Marine biologists at Universite de Rennes and Institut Universitaire de France exposed dolphins at the Planete Sauvage ("Wild Planet") dolphinarium, in Port-Saint-Pere, France, to a series of magnetized objects. They found dolphins swam more aggressively towards semi-submerged barrels emitting a magnetic field. Identical demagnetized barrels served as controls.
