Abstract
Radular teeth of chitons were studied by using magnetic torque-meter and tr ansmission electron microscopy (TEM). The magnetic torque curves give clear evidence of presence of strong uni-axial magnetic anisotropy. The easy axi s is along the length direction of tongue-like radula. The TEM pattern show s that long chip-like magnetite nano-scaled particles packed in the radular teeth with both uni-axial shape anisotropy and magneto-crystalline anisotr opy.
