Summary:A new candidate for a biomagnetic sense organ has been discovered
in the foreheads of sockeye salmon. This candidate is an elliptical cell
encircled by many magnetic particles. The procedures for extracting the
cells are described, and TEM (transmission electron microscopy) pictures
are shown. The minor and major axes of the cells are about 0.65-0.75
μm and 1.3-1.8 μm, respectively, and the diameters of the magnetic
particle range from 50 to 100 nm. The cell also includes a number of
round organelles. A possible mechanism for how this organ senses
magnetic field, that is, a relationship between the motion of magnetic
particles and the applied field, is discussed using a simplified model
