Mollusca Overview - Solon City Schools
... The bivalves are the second largest class of molluscs. They differ from snails in having two shells, usually mirror images of each other. Some like oysters and mussels live attached to rocks and other hard surfaces while others, like pipis, burrow in sand. Leptonoidean bivalves (in picture) are a gr ...

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.
