Nerita is a genus of medium-sized sea snails with a gill and an operculum, marine gastropod molluscs in the family Neritidae, the nerites.

This is the type genus of the family Neritidae.

Contents

Distribution and habitat

Species of Nerita can be found worldwide in tropical waters in the middle and upper intertidal zones. They are gregarious herbivores.

Description

The thick shell is broadly ovate or globular and low-spired. It has a smooth surface. The shells are spirally ribbed or show some axial sculpturing. The ventral side has a large columellar callus or parietal wall. The callus shows small pustules. The aperture and the edge of the columella are usually dentate with fine or robust teeth. The calcareus operculum is thick and can be smooth or with a granular structure. The whorls are covered with strong spiral cords.

Taxonomy

Several subgenera have been proposed in the course of time. But various authors in the past couldn't not agree on the placement of many species. The subgeneric placement of the species of Nerita has been revised by Vermeij in 1984.[1] Inconsistencies still remain over the use and validity of many taxonomic names.[2] as species show a wide variety of colors and patterns, giving rise to many synonyms.
