Hydrobia Acuta Neglecta
'' Hydrobia acuta neglecta'' is a European subspecies of small brackish water snail with a gill and an operculum, an aquatic gastropod mollusk 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 a ...

Hydrobia Ulvae
''Peringia ulvae'' (or ''Hydrobia ulvae''), common name the Laver spire shell or mudsnail, is a European species of very small aquatic snail with gills and an operculum, a gastropod mollusk in the family Hydrobiidae.Gofas, S. (2010). ''Hydrobia ulvae'' (Pennant, 1777). In: Bouchet, P.; Gofas, S.; Rosenberg, G. (2010) World Marine Mollusca database. Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=140126 on 2010-11-27. This is arguably a marine snail, but it is often also listed as a non-marine species because it tolerates brackish water and lives in salt marshes and similar habitats. ''Peringia ulvae'' is the type species of the genus ''Peringia''. Distribution This species occurs on the coasts of the Baltic Sea, the White Sea the Eastern Atlantic and the western Mediterranean Sea, (the Mediterranean records may be in error) including: * Great Britain * Ireland * The Netherlands The type locality is "on the shore ...

Hydrobia Acuta
''Hydrobia acuta'' is a species of very small (4-6mm.) brackish water snail with a gill and an operculum, an aquatic gastropod mollusk in the family Hydrobiidae.

Hydrobiidae
Hydrobiidae, commonly known as mud snails, is a large cosmopolitan family of very small freshwater and brackish water snails with an operculum; they are in the order Littorinimorpha. Distribution Hydrobiidae are found in much of the world, inhabiting all continents except Antarctica. In Australia alone there are over 260 species in the family. Description These are very small or minute snails, with a shell height of less than 8 mm. The dextrally-coiled shells are smooth (except for growth lines conforming to the shape of the outer lip) and are usually rather nondescript. The shell offers very few robust characteristics to the systematist who is attempting to classify the species within this family. This difficulty is compounded by a high degree of intraspecific variation. Descriptions often have to be based on the characteristics of the operculum, radula and penis. The shell of species within this family varies from planispiral to needle-shaped. The shell may hav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Johann Daniel Wilhelm Hartmann
Johann Daniel Wilhelm Hartmann (12 January 1793 – 18 April 1862) was a Swiss painter, engraver and malacologist. Biography He was born in St. Gallen, the son of Georg Leonhard Hartmann (1764-1828), who was also a painter. After training in fine arts with his father in Zurich, Munich and Bern, he worked in St. Gallen from 1826 as a naturalist and miniature painter, heraldist and genealogist. Taxa described by Hartmann include '' Discus ruderatus'', '' Ampullaceana ampla'', '' Trochulus clandestinus'', '' Bythiospeum acicula'', '' Papillifera'' and others. Works *Hartmann, J. D. W. 1821.

Littorinimorpha is a large order of snails, gastropods, consisting primarily of sea snails ( marine species), but also including some freshwater snails ( aquatic species) and land snails (terrestrial species).Bouchet P. & Rocroi J.-P.

The order Littorinimorpha contains many gastropoda families that were formerly placed in the order Mesogastropoda, as introduced by J. Thiele in his work from 1921.
