Trochoidea is a superfamily of small to very large vetigastropod sea snails with gills and an operculum. [2] 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. [3]
This taxon is not the same as a pulmonate land snail genus which is spelled the same way: Trochoidea (genus).
This superfamily consisted of nine following families (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005):
Williams et al. (2008) [4] have made further refinements to the taxonomy of Trochoidea. The revised taxonomy as defined by Bouchet et al. (2017) resulted in the following families. [5] The fossil families, tentatively included in this list, are based on Tracey et al. (1993) [6]

Vetigastropoda is a major taxonomic group of sea snails, marine gastropod mollusks that form a very ancient lineage. Taxonomically the Vetigastropoda are sometimes treated as an order, although they are treated as an unranked clade in Bouchet and Rocroi, 2005.
Turbinoidea was a superfamily of small to large sea snails, marine gastropod mollusks in the clade Vetigastropoda. But it has become an available name, because it is no longer used in the current taxonomy of gastropods sensu Williams et al. (2008).
