Stomatellidae is a family of small marine gastropods now included in the Vetigastropoda.
Contents |
In the earlier classification of the Treatise the Stomatellidae was included in the Archaeogastropoda which is now largely abandoned in favor of the more newly defined Vetigastropoda.
(Note: Gastropod taxonomy has been in flux for more than half a century, and this is especially true currently, because of new research in molecular phylogeny. Because of all the on-going changes, different reliable sources can yield very different classifications.)
The World Register of Marine Species states that Stomatellidae has undergone in 2010 a rank change to Stomatellinae, subfamily of Trochidae
Shells are mostly low-spired with few whorls and lack an umbilicus. Most lack an operculum. The aperture is large, through which the interior of the last whorl is entirely visible from below. The interior of the shell is iridescent because of a layer of nacre.
