In addition, the white scaly-foot sample left on the habitat of black scaly-foot was also investigated.
The mechanism of biomineralization remained as a question and was explored based on electron microscopic observation of cross section of scale and shell. 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. Scaly-foot gastropod, Chrysomallon squamiferum, is a deep-sea snail living on hydrothermal vent that possesses scales with iron sulfide nanoparticles. The scaly-foot snail (Chrysomallon squamiferum) is found in the Indian Ocean in hydrothermal vents fissures in the seafloor, often found near volcanically active places, that eject warm water that’s been heated by molten rock deep below the ocean crust. OKADA Satoshi 国立研究開発法人海洋研究開発機構, 海洋生命理工学研究開発センター, 研究員 (90780916) The newly endangered scaly-foot snail is found in just three locations around the world, all of which are deep-sea hydrothermal vents.Due to the extremely low levels of oxygen found at these.
