Finella
''Finella'' is a genus of sea snails, marine gastropod mollusks in the family Scaliolidae. This genus has been assigned in the course of time to different families by different authors: Rissoidae, Cerithiidae, Dialidae, Obtortionidae, Finellidae and Diastomatidae Morphological and anatomical studies by Winston Ponder in 1994 established that the genera ''Finella'' and '' Scaliola'' didn't belong in the above-mentioned families and he brought them in a new family Scaliolidae. This was supported in 1982 by Healy through the study of the ultrastructure on the spermatozoa. Description The species in this genus contain a small, elongated, conical shell without siphonal canal. The axial to spiral sculpture varies between weak and strong. Distribution The snails of this species are common to even abundant in shallow waters of the tropical Indo-West Pacific Ocean. Species Species within the genus ''Finella'' include: * '' Finella adamsi'' (Dall, 1889) * ''Finella barbarensis'' (B ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cerithioidea
The Cerithioidea is a Taxonomic rank, superfamily of marine, brackish water and freshwater Gastropoda, gastropod containing more than 200 genera. The Cerithioidea are included unassigned in the subclass Caenogastropoda. The original name of this superfamily was Cerithiacea, in keeping with common superfamily endings at the time. Ecology Cerithioidea is a very diverse superfamily. Its species can be found worldwide mainly in Tropics, tropic and subtropic seas on rocky Intertidal zone, intertidal shores, seagrass beds and algal fronds, but also in estuarine and freshwater habitats. The freshwater species are found on all continents, except Antarctica. They are dominant members of mangrove forests, estuarine mudflats, fast-flowing rivers and placid lakes.Healy J. M. & Wells F.

Taxonomy Of The Gastropoda (Bouchet & Rocroi, 2005)
The taxonomy of the Gastropoda as it was revised in 2005 by Philippe Bouchet and Jean-Pierre Rocroi is a system for the scientific classification of gastropod mollusks (Gastropods are a taxonomic class of animals which consists of snails and slugs of every kind, from the land, from freshwater, and from saltwater). The paper setting out this taxonomy was published in the journal '' Malacologia''. The system encompasses both living and extinct groups, as well as some fossils whose classification as gastropods is uncertain. The Bouchet & Rocroi system was the first complete gastropod taxonomy that primarily employed the concept of clades, and was derived from research on molecular phylogenetics; in this context a clade is a "natural grouping" of organisms based upon a statistical cluster analysis. In contrast, most of the previous overall taxonomic schemes for gastropods relied on morphological features to classify these animals, and used taxon ranks such as order, superorder ...

Micromollusk
A micromollusc is a shelled mollusc which is extremely small, even at full adult size. The word is usually, but not exclusively, applied to marine molluscs, although in addition, numerous species of land snails and freshwater molluscs also reach adult size at very small dimensions. These tiny molluscs or their tiny shells are easy to overlook, as many of them are not very noticeable to the naked eye, and thus many people are not aware that they even exist. Nonetheless there are large numbers of families and vast numbers of mollusc species, in particular marine gastropods or sea snails, which are minute enough to be considered micromolluscs. Considerable numbers of marine gastropod species are only about 5 or 6 mm in adult size; many others are only about 2 or 3 mm in adult size; and a few have adult shells which are as small as one millimeter or even smaller still. Micromolluscs are known to have adult shells as small as 600 μm.Geiger et al 2007, Pg. 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Type Genus
In biological taxonomy, the type genus (''genus typica'') is the genus which defines a biological family and the root of the family name. Zoological nomenclature According to the International Code of Zoological Nomenclature, "The name-bearing type of a nominal family-group taxon is a nominal genus called the 'type genus'; the family-group name is based upon that of the type genus." Any family-group name must have a type genus (and any genus-group name must have a type species, but any species-group name may, but need not, have one or more type specimens). The type genus for a family-group name is also the genus that provided the stem to which was added the ending -idae (for families). :Example: The family name Formicidae has as its type genus the genus ''Formica'' Linnaeus, 1758. Botanical nomenclature In botanical nomenclature, the phrase "type genus" is used, unofficially, as a term of convenience. In the '' ICN'' this phrase has no status. The code uses type specimens ...

Freiberger Forschungshefte
The Freiberger or Franches-Montagnes is a Swiss List of horse breeds, breed of horse of draught horse, light draught type. It originates in the cantons of Switzerland, Canton of Canton of Jura, Jura in north-western Switzerland, and is named for the Freiberge or Franches-Montagnes District in the south of that canton. It is widely distributed in Switzerland, and is also present in France and Belgium. It was formerly used principally as a farm horse or by the Swiss army; it is now used mainly for harness horse, driving and riding horse, riding. The is an annual fair for the breed held in Saignelégier, capital of the Franches-Montagnes District. History The Freiberger originates in the historic Canton of Jura, Jura region of Switzerland; use of horses in agricultural work and as post-horses is documented there from about 1620. By the early nineteenth century, there were active breeders in the district of Franches-Montagnes District, Franches-Montagnes. In 1817, there were ...

Félix Pierre Jousseaume
Félix Pierre Jousseaume (12 April 1835 in Charente-Maritime – 3 November 1921) was a French Zoology, zoologist and malacologist. He studied medicine in Paris where he then practised. His thesis was ''Des Végétaux parasites de l'Homme''. He participated in the founding of the Société zoologique de France and was President of that society in 1878. After 1890 he abandoned his practice to study malacology. He made many trips to the Red Sea, giving his collections to the Muséum national d'histoire naturelle. Jousseaume wrote many short scientific papers mainly published in ''Naturaliste, revue illustrée des sciences naturelles'', ''les Nouvelles archives des missions scientifiques et littéraires'', ''la Revue et magasin de zoologie'', and ''le Bulletin de la Société zoologique de France''. He also wrote in 1899 ''La Philosophie aux prises avec la Mer Rouge, le darwinisme et les 3 règnes des corps organisés'' (A. Maloine, Paris : xii + 559 p.), in 1907 ''De l'Attraction et ...

Teleoconch
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 ...
