Rissoinidae
Rissoinidae is a large family (biology), family of Sea snail, sea snails. Members of the Rissoinidae have an operculum and are very small in size. Several genera that were previously part of Rissoinidae have been assigned to the Zebinidae family.Criscione, F., Ponder, W. F., Köhler, F., Takano, T. & Kano, Y.

Zebinella
''Zebinella'' is a genus of minute sea snails, marine (ocean), marine gastropod mollusks or micromollusks, in the family (biology), family Rissoinidae. Description The shell is moderately small and slender. The protoconch consists of about 2½ smooth Whorl (mollusc), whorls. The outer Lip (gastropod), lip is varicose, extending forward. The channel across the basal lip is shallow, slightly undercutting the Columella (gastropod), columella. The parietal wall is callused, forming a channel with the outer lip. The Sculpture (mollusc), sculpture consists of fine axial ribs, between which lie fine spiral threads. Aside from the difference in sculpture, the outer lip is more flaring than in ''Rissoina'' s. s., and the channel across the basal lip is wider and shallower, and does not undercut the columella so strongly.* Species Species within the genus ''Zebinella'' include: * † ''Zebinella abbotti'' (Ladd, 1866) * ''Zebinella alarconi'' (Hertlein & Strong, 1951) * ''Zebinella ...

Gastropod Shell
The gastropod shell is part of the body of many gastropods, including snails, 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, ostracum, is typically made of calcium carbonate (CaCO3) precipitated into an organic matrix ...
