Mollusca Terrestrial mollusks

Short overview

Mollusks belong to the phylum Mollusca in Lophotrochozoa. There aremany classes of mollusks but only one, gastropods (Gastropoda) wassuccessful enough to conquer land.

I GastropodaI Cycloneritimorpha (e.g., Helicina)I Littorinimorpha (e.g., Pomatias)I Pulmonata (most of land gastropods belong here)
