| Outline of Final Research Achievements |
Scaly-foot gastropod, Chrysomallon squamiferum, is a deep-sea snail living on hydrothermal vent that possesses scales with iron sulfide nanoparticles. The appearance of iron sulfide nanoparticles depends on the composition of hydrothermal fluids, namely “black scaly-foot” with iron sulfide nanoparticles, and “white scaly-foot” without iron sulfide. The mechanism of biomineralization remained as a question and was explored based on electron microscopic observation of cross section of scale and shell. In addition, the white scaly-foot sample left on the habitat of black scaly-foot was also investigated. It was revealed that the iron sulfide nanoparticle was synthesized biologically within the scale, not by adsorption of hydrothermally synthesized nanoparticles nor by adsorbed bacteria.
