The present study gives a formal name to the ‘scaly-foot gastropod’, Chrysomallon squamiferum n. gen., n. sp. with Longqi vent field as the type. As greigite is magnetic, the animal actually sticks to magnets. The three known populations of Chrysomallon squamiferum: Kairei, Longqi. Chrysomallon squamiferum Chen, Linse, Copley, & Rogers, For more multimedia, look at Chrysomallon squamiferum on Wikimedia Commons.

Scaly-foot gastropods— Beedessee et al. Present in metapodium buried under layers of sclerites Chen et al.
Maximum-likelihood distance matrix of seven Peltospiridae genera constructed from bp fragment of COI gene. The sclerites of scaly-foot gastropods are also not homologous to the sclerites found in chitons Polyplacophora. In other projects Wikimedia Commons Wikispecies.

Genital slit simple, opening to mantle cavity on right ventral of rectum. The snail’s oesophageal gland squamiferhm symbiotic gammaproteobacteria from which the snail appears to obtain its nourishment.
Laterals solid with reinforced bases, cusps blunt ended, inner and outer side crysimallon finely crenulated. There was, however, a manuscript name, Chrysomallon squamiferumwhich was released with the 16S sequence data filed on GenBank; despite this being a nomen nudum it has been widely quoted in published literature e.
Crysojallon the excretory systemthe nephridium is central, tending to the right side of the body, as a thin dark layer of glandular tissue. This is what makes rotten eggs smell bad, and is toxic to most organisms.
High connectivity of animal populations in deep-sea hydrothermal vent fields in the Central Indian Ridge relevant to its geological setting.
Applied and Environmental Microbiology. Comparative phylogeography among hydrothermal vent species along the East Pacific Rise reveals vicariant processes and population expansion in the South.
New Archaeogastropod limpets from hydrothermal vents: The Snail With an Armor of Iron. The gonads of adult cryosmallon are not inside the shell; they are in the head-foot region on the right side of the squamifefum. The ctenidium provides oxygen for the snail, but the circulatory system is enlarged beyond the scope of other similar vent gastropods.
