Evidence from Strandings for Geomagnetic Sensitivity in Cetaceans [PDF]

, 1986
We tested the hypothesis that cetaceans use weak anomalies in the geomagnetic field as cues for orientation, navigation and/or piloting. Using the positions of 212 stranding events of live animals in the Smith sonian compilation which fall within the ...
