CRYSOMALLON SQUAMIFERUM PDF

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.
