Naticarius is a genus of the moon snails (Naticidae). It wasfirst describedby Dumeril in 1806. Often Naticarius is also considered a subgenus of the genus Natica .

Appearance

Like the species of the genus Natica , the Naticarius species usually have a small to medium-sized, spherical housing with a few, rapidly increasing whorls. The thread is often not particularly high and has a shallow apex . The surface of the housing is usually smooth and usually shows a typical coloration or drawing (e.g. Naticarius onca ), which in most cases allows a determination of the different species. In the event of danger, the housing is closed by a calcareous operculum . In contrast to species of the genus Natica , the operculum of the Naticarius species has circular, parallel depressions (multisulcate).

Way of life

The species of the genus Naticarius are typical soft-ground inhabitants that are found predominantly in tropical and subtropical regions. With their swellable foot they plow through the sandy soil for other mollusks . Their specially formed radula enables them to pierce the shells of sea ​​snails and mussels and to suck out the soft tissues.

Systematics

The type species of the genus Naticarius is Naticarius carena (subsequent monotypical assignment by Froriep in 1806).
