Scaly-foot gastropod
Chrysomallon squamiferum, common name the scaly-foot gastropod, is a species of deep-sea hydrothermal vent snail, a marine gastropod mollusc in the family Peltospiridae.According to WoRMS, ""the name Chrysomallon or Crysomallon squamiferum was used in several databases and academic papers prior to 2015. However, the name was first validly published in the sense of the International Code of Zoological Nomenclature by Chen et al. (2015)"".
