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.

Similarly, a number of neomphalines e. Dorsal view of Chrysomallon squamiferum showing a mantle cavity overview. Van; Vrijenhoek, Robert C. Chrysomallon squamiferumcommon name the scaly-foot gastropodis a species of deep-sea hydrothermal-vent snaila marine gastropod mollusc in the family Peltospiridae.

The abundance of scaly-foot gastropods was lower in the Kairei field than in the Longqi field.

A new genus and species of neomphalid limpet from the Mariana vents: Average shell diameter 32 mm for squamifetum specimensmaximum shell diameter Thank you for subscribing. In this species, the sides of the snail’s foot are extremely unusual, in that they are armoured with hundreds of iron-mineralised sclerites ; these are composed of iron sulfides [6] greigite and pyrite.

Alignment and editing of genetic sequences were carried out in Geneious v. A five-gene Bayesian phylogenetic reconstruction does not contradict the placement within Peltospiridae. Cusp of central tooth blunt-ended, not crenulated.

Shell parameters of Chrysomallon squamiferum n. The middle organic layer appears to absorb mechanical strain and energy generated by a squeezing attack for example by the claws of a crabmaking the shell much tougher.


Node values are Bayesian posterior probabilities. The three known populations of Chrysomallon squamiferum: It is hypothetized that the derived strategy of housing endosymbiotic microbes in an oesophageal gland, has been the catalyst for anatomical innovations that serve primarily to improve the fitness of the bacteria, over and above the needs of the snail.

Listing, impact assessment and prioritization of introduced land snail and slug species in Indonesia. Chrysomallon also has a truncated comb-like ending to the marginal teeth, which is present in only the Peltospiridae and Melanodrymiidae.

Peltospiridae from the Indian Ocean”. Across the East Pacific Rise the vent limpet Lepetodrilus elevatusalso with lecithotrophic development, was shown to exhibit significant genetic differentiation Plouviez et al. Ferrimagnetic when coated with iron sulphide layer. Teredinidae extends wooden-steps theory”.

Scaly-foot gastropod is magnetic and sticks to magnets. Kairei, Longqi, Solitaire left to right. The water in these vents are high in sulfides and metals, which the snails have incorporated into their shells. Melanodrymiidae from sunken wood.

The name is given in reference to the metal coating often found on the gastropod’s shell and sclerites, which includes pyrite, commonly known as fool’s gold.
