Diverse animals can detect magnetic fields but little is known about how
they do so. Three main hypotheses of magnetic field perception have been
proposed. Electrosensitive marine fish might detect the Earth's field
through electromagnetic induction, but direct evidence that induction
underlies magnetoreception in such fish has not been obtained. Studies in
other animals have provided evidence that is consistent with two other
mechanisms: biogenic magnetite and chemical reactions that are modulated by
weak magnetic fields. Despite recent advances, however, magnetoreceptors
have not been identified with certainty in any animal, and the mode of
transduction for the magnetic sense remains unknown.
