Cratidentium is a genus of small sea snails, marine gastropod mollusks in the family Trochidae, the top-snails. [1]
Species within the genus Cratidentium include:
The Trochidae, common name top-snails or top-shells, are a family of various sized sea snails, marine gastropod molluscs in the subclass Vetigastropoda. This family is commonly known as the top-snails because in many species the shell resembles a toy spinning top.
Calliostoma is a genus of small to medium-sized sea snails with gills and an operculum, marine gastropod molluscs within the family Calliostomatidae, the Calliostoma top snails. Previously this genus was placed within the family Trochidae. Calliostoma is the type genus of the family Calliostomatidae.
Calliostomatidae is a family of sea snails within the superfamily Trochoidea and the clade Vetigastropoda.
Diloma is a genus of medium-sized sea snails, marine gastropod mollusks in the family Trochidae, the top snails.
Stomatellinae is a subfamily of small sea snails with a brilliantly nacreous interior of the shell, marine gastropod mollusks in the family Trochidae, the top snails.
Trochoidea is a superfamily of small to very large vetigastropod sea snails with gills and an operculum. Species within this superfamily have nacre as the inner shell layer. The families within this superfamily include the Trochidae, the top snails. This superfamily is the largest vetigastropodan superfamily, containing more than 2,000 species.
Fossarina is a genus of sea snails, marine gastropod molluscs in the family Trochidae, the top shells.
Austrocochlea is a genus of medium-sized sea snails, marine gastropod molluscs in the family Trochidae, the top snails, also known as top shells.
Monodonta is a genus of sea snails, marine gastropod mollusks in the family Trochidae, the top snails.
Osilinus is a genus of sea snails, marine gastropod mollusks in the family Trochidae, the top snails.
Oxystele is a genus of sea snails, marine gastropod mollusks in the family Trochidae, the top snails. Although previously suggested as a subgenus of Diloma, genetic analysis has shown it to be more appropriate as its own genus.
Coelotrochus is a genus of small sea snails, marine gastropod mollusks in the family Trochidae, the top snails.
The Fossarininae are a taxonomic subfamily of very small to large sea snails, marine gastropod molluscs in the family Trochidae, common name top snails.
Pictodiloma is a genus of sea snails, marine gastropod mollusks in the family Trochidae, the top snails.
Chlorodiloma is a genus of sea snails, marine gastropod mollusks in the family Trochidae, the top snails.
Roseaplagis rufozona is a species of sea snail in the family Trochidae, the top snails.
Trochus kotschyi, common name the Kotschy's gibbula, is a species of sea snail, a marine gastropod mollusk in the subfamily Trochinae of the family Trochidae, the top snails.
Austrocochlea constellata is a species of sea snail, a marine gastropod mollusk in the family Trochidae, the top snails.
Maurea is a genus of sea snails, marine gastropod mollusks, in the family Calliostomatidae within the superfamily Trochoidea, the top snails, turban snails and their allies.
