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 ...

Rodolfo Amando Philippi
Rodolfo Amando (or Rudolph Amandus) Philippi (14 September 1808 – 23 July 1904) was a German–Chilean paleontologist and zoologist. Philippi contributed primarily to malacology and paleontology, but also published a major work on Diptera of Chile. His grandson, Rodulfo Amando Philippi Bañados (1905-1969), was also a zoologist and in order to avoid confusion in zoological nomenclature, the elder is referred to as "Philippi rumwiede to distinguish him from his grandson "Philippi añados. Early life Philippi was born in Charlottenburg, Berlin to Johann Wilhelm Eberhard Philippi, a Prussian government auditor, and his third wife Maria Anna Krumwiede (m. 1806). The father had five children from two earlier marriages and Philippi was the eldest from the third marriage. In 1818, Philippi, his younger brother Bernhard Eunom (1811–1852) and their mother went to Yverdon-les-Bains, Switzerland, where they were educated at the Pestalozzian Institute founded by Johann Heinrich P ...

Hydrobia Acuta Neglecta
'' Hydrobia acuta neglecta'' is a European subspecies of small brackish water snail with a gill and an operculum, an aquatic gastropod mollusc in the family Hydrobiidae. Distribution This species which has a distribution type: oceanic temperate occurs on the coasts of the North Sea, in countries and islands including: * Iceland * Denmark * Sweden * Great Britain * Ireland * France Ecology ''Hydrobia acuta neglecta'' occurs in coastal lagoons where incoming freshwater dilutes sea water. The preferred salinity range is 10-24 ‰. Status The status of this taxon is uncertain. ''Hydrobia neglecta'' is treated as a full species in Fauna Europaea, but in 1995 it had been suggested that ''H. neglecta'' is a synonym of the Mediterranean ''Hydrobia acuta'' (Draparnaud). Then a ''neglecta'' colony in northern France was shown to be ''acuta''. In 2000 a molecular study concluded that north-west European populations were not specifically distinct from the Mediterranean ''Hydrobia acuta' ...

Jacques Philippe Raymond Draparnaud
Jacques Philippe Raymond Draparnaud (3 June 1772, Montpellier – 2 February 1804) was a French naturalist, malacologist and botanist. He is considered the father of malacology in France. He was professor of medicine and pathology at the Faculté de Médecine de Montpellier. Draparnaud understood the breadth of the fauna he studied, as can be seen in a quote from him, in ''Histoire Naturelle des Mollusques'', published in 1805:Au reste, quoique j'aie décrit pour la France seule un bien plus grand nombre d'espèces que Muller et Schroeter n'ent ont fait connoître pour l'Europe entière, et trois fois autant que Geoffroy et Poiret n'en ont observé dans les environs de Paris, je suis convaincu qu'il reste encore en ce genre bien des découvertes à faire. Translation: As for the remainder, even though I have described for France a greater number of species than Müller and Schroeter made known for the whole of Europe, and three times as many as Geoffroy and Poiret observed aro ...
