Chrysomallon
''Chrysomallon squamiferum'', common name, commonly known as the scaly-foot gastropod, scaly-foot snail, sea pangolin, or volcano snail, is a species of deep-sea hydrothermal vent, hydrothermal-vent snail, a marine gastropod mollusc in the family Peltospiridae. This vent-endemic gastropod is known only from deep-sea hydrothermal vents in the Indian Ocean, where it has been found at depths of about . ''C. squamiferum'' differs greatly from other deep-sea gastropods, even the closely related neomphalines. In 2019, it was declared Endangered species, endangered on the IUCN Red List, the first species to be listed as such due to risks from deep-sea mining of its vent habitat. The shell is of a unique construction, with three layers; the outer layer consists of iron sulphides, the middle layer is equivalent to the organic periostracum found in other gastropods, and the innermost layer is made of aragonite. The foot is also unusual, being armored at the sides with iron-mineralised scle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
