Cardioidea is a taxonomic superfamily of saltwater clams, marine bivalve molluscs consisting of the extant Cardiidae (cockles) and the extinct Pterocardiidae.
These families are assigned to Cardioidea: [1]
Cymbuliidae is a family of pelagic sea snails or "sea butterflies", marine gastropod mollusks in the superfamily Cymbulioidea.
The Clionidae are a family of sea angels, which are a group of pelagic marine gastropods.
Pyramidellinae is a taxonomic subfamily of minute sea snails, marine gastropod mollusks in the family Pyramidellidae, the pyrams and their allies.
Tegula is a genus of small to medium-sized sea snails, marine gastropod molluscs in the family Tegulidae.
The Trochidae, common name top-snails or top-shells, are a taxonomic family of very small to large sea snails, marine gastropod molluscs in the clade Vetigastropoda.
Haustrinae is a taxonomic subfamily of predatory sea snails, marine gastropod mollusks in the family Muricidae, the murex shells or rock shells.
Haustrum is a genus of sea snails, marine gastropod mollusks in the subfamily Haustrinae of the family Muricidae, the murex snails or rock snails.
Hippopus is a genus of large tropical saltwater clams, marine bivalve molluscs in the subfamily Tridacninae, the giant clam subfamily, of the family Cardiidae.
The Vermetidae, the worm snails or worm shells, are a taxonomic family of small to medium-sized sea snails, marine gastropod molluscs in the clade Littorinimorpha. The shells of species in the family Vermetidae are extremely irregular, and do not resemble the average snail shell, hence the common name "worm shells" or "worm snails".

This family includes the slipper snails (Crepidula), hat snails (Calyptraea), spiny slipper snails (Bostrycapulus), and cup-and-saucer snails (Crucibulum) as well as Crepipatella, Siphopatella, Grandicrepidula, and Maoricrypta.
Ptychatractidae is a taxonomic family of sea snails, marine gastropod mollusks in the superfamily Turbinelloidea.
Pyramidella is a genus of minute to medium-sized sea snails, marine gastropod mollusk in the family Pyramidellidae, the pyrams and their allies.
Smaragdia is a genus of small sea snails, marine gastropod mollusks in the family Neritidae, the nerites.
