      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.
