This species has a unique characteristics among gastropods, it carries hundreds of dermal sclerites on its foot. Sclerites: curved, elongate, proteinaceous, not calcified; ca. 1x 5 mm in size in adults; white to mettalic black depending on extent of iron sulphide coating; newly grown sclerites milky white. Ferrimagnetic when coated with iron sulphide layer. Shell: three whorls, globose with depressed spire, tighly coiled. Aperture elliptic, very large. Operculum: present in metapodium buried under layers of sclerites; multispiral, concentric in juveniles while curved, bent shape in adults. |
| Populations are found in hydrothermal vents several miles below the ocean surrounded with toxic chemicals and high temperatures reaching more than 300 deg C (Ref. 127038). Food is provided by bacteria that grow inside a special pouch in the snail's throat by converting the chemicals in the vents into energy (Ref. 127038). |
