Calliostomatidae
Calliostomatidae is a family of sea snails within the superfamily Trochoidea and the clade Vetigastropoda.
Description
The Calliostomatidae are unusually diverse. They are characterized by a stepped spire and a pointy aperture. They may possess or lack an umbilicus. The columella is sometimes thicker, partially covering the aperture. The spiral whorls can differ between narrow and robust. They inhabit a wide range of ocean habitats, from the intertidal zone to mid-bathyal depths.
Taxonomy
For a long time, this taxon was considered to be a subfamily of the Trochidae.
2005 taxonomy
This family consists of two following subfamilies (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005):[1]
- subfamily Calliostomatinae Thiele 1924 (1847)
- tribe Calliostomatini Thiele 1924 (1847) - synonym: Ziziphininae Gray, 1847
- tribe Fautricini Marshall, 1995
- subfamily Thysanodontinae Marshall, 1988
2008 taxonomy
According to Williams et al. (2008)[2] the Calliostomatidae stays in Trochoidea. Up to 2008 there were only two species Calliostoma javanicum and Calliostoma unicum that were used in molecular phylogeny studies.[2]
2010 taxonomy
The first molecular phylogeny study of the family Calliostomatidae was made by Williams et al. (2010)[3] Based on molecular data, they confirmed that Thysanodontinae Marshall, 1988 belongs to the family Calliostomatidae,[3]. It was already previously placed there based on morphological data.[3]
