Description

The Calliostomatidae are unusually diverse. They are characterized by a stepped spire and a pointy

aperture In optics, the aperture of an optical system (including a system consisting of a single lens) is the hole or opening that primarily limits light propagated through the system. More specifically, the entrance pupil as the front side image o ...

. They may possess or lack an umbilicus. The collumella is sometimes thicker, partially covering the aperture. The spiral

Taxonomy

This taxon was long considered to be a subfamily of the

Trochidae The Trochidae, common name top-snails or top-shells, are a family of various sized sea snails, marine gastropod molluscs in the subclass Vetigastropoda. This family is commonly known as the top-snails because in many species the shell resembles ...
