Aporrhaidae
Aporrhaidae is a family of sea snails commonly called the "pelican's foot snails." The taxonomy of the Gastropoda by Bouchet & Rocroi, 2005Bouchet P. & Rocroi J.-P. (Ed.); Frýda J., Hausdorf B., Ponder W., Valdes A. & Warén A. 2005. ''Classification and nomenclator of gastropod families''. Malacologia: International Journal of Malacology, 47(1-2). ConchBooks: Hackenheim, Germany. . ISSN 0076-2997. 397 pp. http://www.vliz.be/Vmdcdata/imis2/ref.php?refid=78278 categorizes Aporrhaidae as marine gastropod mollusks in the clade Littorinimorpha. Aporrhaids are commercially important, especially in traditional fisheries. Description Aporrhaids have a large lip with finger-like extensions, and a small operculum. They do not have movable eyes. Instead, their eyes are fixed at the base of each tentacle. The mollusk has one narrow foot, which renders its motion interrupted as the foot must raise the shell a tiny bit in each single movement, simultaneously pushing it forward. The motio ...

List Of Marine Gastropod Genera In The Fossil Record
This list of marine gastropod genera in the fossil record is an attempt to list all the genera of sea snails or marine gastropod mollusks which have been found in the fossil record. Nearly all of these are genera of shelled forms, since it is relatively rare for gastropods without a shell (sea slugs) to leave any recognizable traces. It is also worth pointing out that this list of genera represents only a very tiny fraction of the number of genera that must actually have existed over the evolutionary time span: the fossil record is an extremely patchy and exceedingly incomplete pteryrecord of life on earth in earlier geological eras. Many genera on this list are still extant, are still living now. On the current version of this list, some extant genera are mistakenly marked as extinct, with a "†" next to the name, but this should slowly become more accurate over time as corrections are made. The list consists of formal genera names in the class Gastropoda; it excludes purely ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mollusc
Mollusca is the second-largest phylum of invertebrate animals after the Arthropoda, the members of which are known as molluscs or mollusks (). Around 85,000 extant species of molluscs are recognized. The number of fossil species is estimated between 60,000 and 100,000 additional species. The proportion of undescribed species is very high. Many taxa remain poorly studied. Molluscs are the largest marine phylum, comprising about 23% of all the named marine organisms. Numerous molluscs also live in freshwater and terrestrial habitats. They are highly diverse, not just in size and anatomical structure, but also in behaviour and habitat. The phylum is typically divided into 7 or 8 taxonomic classes, of which two are entirely extinct. Cephalopod molluscs, such as squid, cuttlefish, and octopuses, are among the most neurologically advanced of all invertebrates—and either the giant squid or the colossal squid is the largest known invertebrate species. The gastropods ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gastropod
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.

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] |

The Stromboidea, originally named the Strombacea by Rafinesque in 1815, is a superfamily of medium-sized to very large sea snails in the clade Littorinimorpha.MolluscaBase eds. (2020). MolluscaBase. Stromboidea Rafinesque, 1815. Accessed through: World Register of Marine Species at: http://www.marinespecies.org/aphia.php?p=taxdetails&id=14770 on 2020-05-24 Morphology Shell Stromboideans have medium to large shells, attaining a wide variety of lengths depending on the species (20–400 mm from the smallest aporrhaids to the largest strombids). A stromboidean shell has a medium (e.g. spider conchs, ''Lambis'' spp.) to high spire (e.g. tibias, ''Tibia'' spp.), and a thickened and frequently expanded outer lip (e.g. the queen conch, ''Lobatus gigas'', or the goliath conch, '' Lobatus goliath'') that may be ornamented by long spines (e.g. the spider conch, ''Lambis chiragra'', common pelican foot, ''Aporrhais'' spp.) or digitations (e.g. the millipede spider conch, ''Lambis m ...

Maurice Cossmann
Maurice Cossmann, full name Alexandre Édouard Maurice Cossmann (18 September 1850 – 17 May 1924) was a French paleontologist and malacologist. Maurice Cossmann's father was an artist draughtsman and a talented lithographer. His early education was at Condorcet College in Paris and he later gained the Diploma of the Central School of Arts and Manufacturing in the same city. He was then employed by the Compagnie des chemins de fer du Nord. Cossmann made all his career there, finally as Chief of the Engineering services (Ingénieur Chef des Services Techniques). Married and without a child, he loved to tell how the arrival of a small collection of fossils had led to his future studies of paleontology. Cossman specialised in the fossils of the Paleogene and Neogene periods. Certain of his works are still a major reference especially: *''Iconographie complète des coquilles fossiles de l'Éocène des environs de Paris'', in English Iconography of the fossil shells of the Eocen ...
