Coralliophila Problematica
''Coralliophila'' is a genus of sea snails, marine (ocean), marine gastropod mollusks in the subfamily Coralliophilinae, the coral snails, within the family (biology), family Muricidae, the murex snails and rock snails. The genus ''Coralliophila'' is most probably polyphyletic and should be restricted to the species most closely related to the type species. Species in the genus'' Hirtomurex'', situated in the Indo-West Pacific are not clearly distinguishable from the species in the genus ''Coralliophila'' ''sensu lato'' (in the broad sense) found in the Eastern Atlantic. Description The outer and inner Lip (gastropod), lips of the shell are irregular. They are moderate, not produced into an extended process closing the Aperture (mollusc), aperture. Species Species within the genus ''Coralliophila'' s.l. include: * ''Coralliophila aberrans'' (C. B. Adams, 1850) * ''Coralliophila abnormis'' (E.A. Smith, 1878) * ''Coralliophila adansoni'' Kosuge & Fernandes, 1989 * ''Coralliop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...
