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.

This is consistent with the generic rank of Chrysomallon.

Very large for Peltospiridae, up to Rapid convergence at hydrothermal vents shown by 3D anatomical reconstruction of Gigantopelta Mollusca: Each layer appear to contribute to the effectiveness of the snail’s defense in different ways.

The sqaumiferum selected were as follows: Determining diet and establishing a captive population of a rare endemic detritivore, the endangered Novisuccinea chittenangoensis Pilsbry, Pulmonata: In Chrysomallon squamiferumthe soft parts of the animal occupy approximately two whorls of the interior of the shell.

Scatterplot of shell diameter vs shell height of 50 specimens of Chrysomallon squamiferum n. Maximum-likelihood distance matrix of seven Peltospiridae genera constructed from bp fragment of COI gene. Although this species has a similar shell shape and general form to other peltospirids, the ctenidium is proportional size to that of Hirtopeltawhich has the largest gill among peltospirid genera that have been investigated anatomically so far.


The scaly-foot gastropod has a thick snout, which tapers distally to a blunt end. Its outer shell is covered dquamiferum a layer of iron, and its soft fleshy foot that protrudes from the under the shell is protected by hard mineralized scales made of iron sulphides. Chrysomallon squamiferum from Longqi. Shell measurements were carried out with digital vernier callipers.

Crysomallon squamiferum — Yao et al. Proceedings of the National Academy of Sciences.

The sclerites of Chrysomallon squamiferum are mainly proteinaceous conchiolin is a complex protein ; in contrast, the sclerites of chitons are mainly calcareous. Coiled shell with three whorls; squamifegum compressed; aperture elliptic.

Longqi vent field, SWIR. The abundance of scaly-foot gastropods was lower in the Kairei field than in the Longqi field. Scaly-footed gastropods— Tao et al. Cephalic tentacles elongate, thick at base, tapering to fine point at distal tip. The respiratory system and circulatory system consist of a single left bipectinate ctenidium gillwhich is very large How the mollusc got its scales: From Wikipedia, the free encyclopedia.

Similarly, a number of neomphalines e.

Vetigastropod phylogeny and a new concept of Seguenzioidea: From published figures, specimens from Kairei and Solitaire vent fields in CIR appear to have broader sclerites than those from Longqi cf. The total sequence lengths used were 2, bp for the five-gene tree and bp for the Squqmiferum tree. Geoffrey; Schultz, Thomas F. Chrysomallon squamiferum from the Kairei vent field. Fill in your details below or click an icon to log in: As it cannot be assigned to any of crysomallln described genera in the family, a new genus Chrysomallon is erected to house this species, named here as Chrysomallon squamiferum n.


Cycle sequencing reactions were carried out with the protocol: This page was last edited on 31 Decemberat List of clade, family, species and genes used in the five-genes phylogenetic reconstruction with GenBank accession numbers. A five-gene Suqamiferum phylogenetic reconstruction does not contradict the placement within Peltospiridae. The sclerites of scaly-foot gastropods are also not homologous to the sclerites found in chitons Polyplacophora.

It has not been formally named, despite attracting great attention from both scientists and the general public alike, although a manuscript name has occasionally been suamiferum in various sources. Cusp of central tooth blunt-ended, not crenulated.

The innermost layer is made of aragonite, a form of calcium carbonate that is commonly found both in the shells of molluscs and in various corals.
