Neritimorpha is a taxonomic grouping, an unranked clade of snails, gastropod mollusks. This grouping includes land snails, sea snails, some deepwater limpets, and also freshwater snails. This clade used to be known as the superorder Neritopsina.

The clade Neritimorpha is, based on optimal phylogenetic analysis, deemed monophyletic.[1]

1997 taxonomy[edit]

According to the taxonomy of the Gastropoda (Ponder & Lindberg, 1997) Neritopsina is a gastropod superorder in the subclass Orthogastropoda. The superfamily Palaeotrochoidea is contained within Neritopsina but its order placement is undetermined.

2005 taxonomy[edit]

The taxonomy of the Gastropoda by Bouchet & Rocroi, 2005[2] categorizes Neritimorpha as a gastropod mollusk clade. It is one of the 6 highest clades in Gastropoda. It contains the clades Cyrtoneritimorpha, Cycloneritimorpha, as well as Paleozoic Neritimorpha of uncertain position.

Clades (and uncertain position taxa) in Neritimorpha include:

Four extant superfamilies are recognised: Helicinoidea, Hydrocenoidea, Neritoidea and Neritopsoidea.
