Trochinae
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 a toy spinning top. Taxonomy The family Trochidae consists of the following subfamilies: * Alcyninae Williams, Donald, Spencer & Nakano, 2010 * Cantharidinae Gray, 1857 * Carinotrochinae S.-Q. Zhang, J. Zhang & S.-P. Zhang, 2020 * Chrysostomatinae Williams, Donald, Spencer & Nakano, 2010 * Fossarininae Bandel, 2009 * Halistylinae Keen, 1958 * Kaiparathininae B. A.

Gastropod Shell
The gastropod shell is part of the body of a Gastropoda, gastropod or snail, a kind of mollusc. The shell is an exoskeleton, which protects from predators, mechanical damage, and dehydration, but also serves for muscle attachment and calcium storage. Some gastropods appear shell-less (slugs) but may have a remnant within the mantle, or in some cases the shell is reduced such that the body cannot be retracted within it (semi-slug). Some snails also possess an operculum that seals the opening of the shell, known as the Aperture (mollusc), aperture, which provides further protection. The study of mollusc shells is known as conchology. The biological study of gastropods, and other molluscs in general, is malacology. Shell morphology terms vary by species group. Shell layers The gastropod shell has three major layers secreted by the Mantle (mollusc), mantle. The calcareous central layer, tracum, is typically made of calcium carbonate precipitated into an organic matrix known as c ...

Enida
''Enida'' is a genus of sea snails, marine gastropod mollusks in the family Trochidae, the top snails (not assigned to a subfamily). Description The shell has a depressed-conical shape. It is widely umbilicate. The convex whorls are concentrically granose-lirate. The sutures are canaliculate. The body whorl is carinated or angulated. The aperture is subquadrate. The outer lip is simple, or lirate within. The inner lip is reflexed. The umbilicus is large. The margin is crenulated. Species Species within the genus ''Enida'' include: * ''Enida persica'' Melvill, J.C. & R. Standen, 1903 * ''Enida japonica'' A. Adams, 1860 * ''Enida taiwanensis ''Enida taiwanensis'' is a species of sea snail, a marine gastropod mollusk in the family Trochidae, the top snails.
