Cerithioidea
The Cerithioidea is a superfamily of marine, brackish water and freshwater gastropod containing more than 200 genera. The Cerithoidea 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 tropic and subtropic seas on rocky 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.

Batillariidae
Batillariidae, common name batillariids or mudcreepers, are a family of marine, cerithioidean gastropod molluscs in thesuperfamily Cerithioidea. They consist of 14 living species, classified in six to eight genera.Ozawa, T., Köhler, F., Reid, D.G., Glaubrecht, M. 2009. Tethyan relicts on continental coastlines of the northwestern Pacific Ocean and Australasia: molecular phylogeny and fossil record of batillariid gastropods (Caenogastropoda: Cerithioidea). ''Zoologica Scripta'', 38: 503-525. According to the taxonomy of the Gastropoda by Bouchet & Rocroi (2005) the family Batillariidae has no subfamilies. However, a recent molecular study has found that the Batillariidae as traditionally conceived are not monophyletic. The Neotropical genera ''Lampanella'' and ''Rhinocoryne'' are sister to the Planaxidae. The monophyletic Batillariidae sensu stricto are restricted to the northwestern Pacific and Australasia. A revised generic classification has been suggested that is consistent ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cerithiidae
Cerithiidae, common name the cerithiids or ceriths, is a large family of medium-sized marine gastropods in the clade Sorbeoconcha. Distribution Ceriths are found worldwide on sandy bottoms, reef flats or coral reef rock covered with sand and algae in the sublittoral zone of warm or temperate waters. Most are found in tropical areas. A few occur along the European coastline and about 30 species in two genera are found along the American coast. A few species occur in estuarine areas of mangrove forests close to the sea. Only a few species of the subfamily Bittiinae are found in deep water. Diet Ceriths are herbivores and detritivores that graze the sea bed. Description Their slender shell is elongated with a pointed spire. They vary in size from 3 mm ('' Bittium alternatum'') to 150 mm ('' Cerithium nodulosum''). The smallest shells are found in the subfamily Bittiinae. The many whorls have radial sculpture with axial ridges and nodules. The aperture shows at ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caenogastropoda
Caenogastropoda is a taxonomic clade, a large diverse group which are mostly sea snails and other marine gastropod mollusks, but also includes some freshwater snails and some land snails. The clade is the most diverse and ecologically successful of the gastropods. Caenogastropoda contains many families of shelled marine molluscs – including the periwinkles, cowries, wentletraps, moon snails, murexes, cone snails and turrids – and constitutes about 60% of all living gastropods. Biology The Caenogastropoda exhibit torsion, and thus are included in what was previously called the Streptoneura (meaning ''twisted nerves''), also known as Prosobranchia (meaning ''gills forward''). Specifically, they are characterized by having only a single auricle in the heart and a single pair of gill leaflets, and are equivalent to the Monotocardia or Pectinobranchia of older authors. Taxonomy The taxon Caenogastropoda was first established by Leslie Reginald Cox in 1960 as a supero ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 ...

Potamididae
''Potamididae'', common name potamidids (also known as horn snails or mudwhelks) are a family of small to large brackish water snails that live on mud flats, mangroves and similar habitats. They are amphibious gastropod molluscs in the superfamily Cerithioidea. Traditionally, potamidids and batillariids have been confused because they have similar shells and they live in similar environments. For many fossil taxa the family assignment to either of these two families is still unresolved or controversial. According to the taxonomy of the Gastropoda by Bouchet & Rocroi (2005) the family Potamididae has no subfamilies. Distribution The distribution of Potamididae includes the Indo-West Pacific, the eastern Pacific and the Atlantic Ocean. Genera Six living and a number of fossil genera are currently recognized: Recent genera: * ''Cerithidea'' Swainson, 1840 * ''Cerithideopsis'' Thiele, 1929 ** possible subgenus or synonym: † '' Harrisianella'' Olson, 1929 - Reid et al.

Gastropoda
The gastropods (), commonly known as snails and slugs, belong to a large taxonomic class of invertebrates within the phylum Mollusca called Gastropoda (). This class comprises snails and slugs from saltwater, from freshwater, and from land. There are many thousands of species of sea snails and slugs, as well as freshwater snails, freshwater limpets, and land snails and slugs. The class Gastropoda contains a vast total of named species, second only to the insects in overall number. The fossil history of this class goes back to the Late Cambrian. , 721 families of gastropods are known, of which 245 are extinct and appear only in the fossil record, while 476 are currently extant with or without a fossil record. Gastropoda (previously known as univalves and sometimes spelled "Gasteropoda") are a major part of the phylum Mollusca, and are the most highly diversified class in the phylum, with 65,000 to 80,000 living snail and slug species.

Malacological Review
Malacology is the branch of invertebrate zoology that deals with the study of the Mollusca (mollusks or molluscs), the second-largest phylum of animals in terms of described species after the arthropods. Mollusks include snails and slugs, clams, and cephalopods, along with numerous other kinds, many of which have shells. One division of malacology, conchology, is devoted to the study of mollusk shells. Malacology derives . Fields within malacological research include taxonomy, ecology and evolution. Applied malacology studies medical, veterinary, and agricultural applications; for example, mollusks as vectors of disease, as in schistosomiasis. Archaeology employs malacology to understand the evolution of the climate, the biota of the area, and the usage of the site. In 1681, Filippo Bonanni wrote the first book ever published that was solely about seashells, the shells of marine mollusks. The book was entitled: In 1868, the German Malacological Society was founded. Zoological ... [...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 ...
