0 Comments

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.

The harsh environment has caused the snail to develop a unique exoskeleton. Prospects for inferring very large phylogenies by using the neighbor-joining method.

Scaly-foot gastropod – Wikipedia

Within the Peltospiridae, the new genus can easily be distinguished from the limpet-form genera Echinopelta McLean, ; Nodopelta McLean, and Rhynchopelta McLean,as it has a distinctly coiled shell with approximately three whorls. Interestingly a number of active vents have been inferred between Longqi and Kairei e.

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.
