Tritonium
''Tritonium'' is a genus of sea snails, marine gastropod mollusks in the family Cancellariidae, commonly known as the nutmeg snails. The genus name Tritonium has been given twice to species with a different type species : * ''Tritonium'' O.F. Müller, 1776 : type species ''Buccinum undatum'' Linnaeus, 1758 (given by Stewart in 1926); this makes this name an objective synonym of '' Buccinum''. * ''Tritonium'' Röding, 1798 : type species : ''Murex tritonis'' Linnaeus, 1758 (given by Cossman in 1903); this makes this name an objective synonym of '' Charonia'' Gistel, 1847. Neither of these original names is valid. Confusion increased when, during the 18th and 19th century, authors added species but didn't specify to which ''Tritonium'' they belonged. The authors of the World Register of Marine Species (WoRMS) have arbitrarily attributed the species now placed in Buccinidae, Muricidae, and other neogastropod families, to ''Tritonium'' O.F. Müller, 1776. The species now placed i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

''Tritonium submuricatum'' is a species of sea snail, a marine gastropod mollusk in the family Cancellariidae, the nutmeg snails. As the genus name ''Tritonium'' is no longer accepted, this species name has become a "species inquirenda In biological classification, a ''species inquirenda'' is a species of doubtful identity requiring further investigation.

Buccinum
''Buccinum'' is a genus of medium-sized sea snails, marine gastropod molluscs in the family Buccinidae, the true whelks.Gofas, S.; Bouchet, P. (2014). Buccinum Linnaeus, 1758. Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=137701 on 2015-02-18 Snails in this genus are commonly called ''whelks'', a name shared with several related and unrelated species. The common whelk ''Buccinum undatum'' is the most common representative of the genus in the northern Atlantic Ocean. Description The shell is ovate or ovate-conical and elongated. The spire is moderate and pointed. The aperture is oval or oblong with a deep notch anteriorly and without a siphonal canal. The columella is plain, not flattened, swollen above, and often covered with a wide and flattened calcareous callosity, of more diaphanous substance. There sometimes exists a fold at the base of the columella. The outer lip is plain, quite thin, sometimes recurved, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charonia
''Charonia'' is a genus of very large sea snail, commonly known as Triton's trumpet or Triton snail. They are marine gastropod mollusks in the monotypic family Charoniidae. Etymology The common name "Triton's trumpet" is derived from the Greek god Triton, who was the son of Poseidon, god of the sea. The god Triton is often portrayed blowing a large seashell horn similar to this species. Fossil records This genus is known in the fossil records as far back as the Cretaceous period. Fossils are found in the marine strata throughout the world. Description Species within the genus ''Charonia'' have large fusiform shells, usually whiteish with brown or yellow markings. The shell of the giant triton ''Charonia tritonis'' (Linnaeus, 1758), which lives in the Indo-Pacific, can grow to over half a metre (20 inches) in length. One slightly smaller (shell size but still very large species, '' Charonia variegata'' (Lamarck, 1816), lives in the western Atlantic, from North Carolina ...

Cancellariidae
Cancellariidae, common name the nutmeg snails or nutmeg shells, are a family of small to medium-large sea snails, marine gastropod mollusks in the clade Neogastropoda. Some of the shells of the species in this family resemble a nutmeg seed. Distribution This family occurs worldwide. Many species are found in deep water. Taxonomy This family consists of three following subfamilies (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005): * Cancellariinae Forbes & Hanley, 1851 - synonym: Trigonostomatinae Cossmann, 1899 * Admetinae Troschel, 1865 - synonym: Paladmetidae Stephenson, 1941 * Plesiotritoninae Beu & Maxwell, 1937 Genera Genera in the family Cancellariidae include: *'' Admete'' Krøyer, 1842 *'' Admetula'' Cossmann, 1889 *'' Africotriton'' Beu & Marshall, 1987 *''Agatrix'' R.

Mollusk
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.

World Register Of Marine Species
The World Register of Marine Species (WoRMS) is a taxonomic database that aims to provide an authoritative and comprehensive list of names of marine organisms. Content The content of the registry is edited and maintained by scientific specialists on each group of organism. These taxonomists control the quality of the information, which is gathered from the primary scientific literature as well as from some external regional and taxon-specific databases. WoRMS maintains valid names of all marine organisms, but also provides information on synonyms and invalid names. It is an ongoing task to maintain the registry, since new species are constantly being discovered and described by scientists; in addition, the nomenclature and taxonomy of existing species is often corrected or changed as new research is constantly being published. Subsets of WoRMS content are made available, and can have separate badging and their own home/launch pages, as "subregisters", such as the ''World List ...

Buccinum Undatum
''Buccinum undatum'', the common whelk or the waved buccinum, is a large, edible marine gastropod in the family Buccinidae, the "true whelks".Fraussen, K.; Gofas, S. (2014). Buccinum undatum Linnaeus, 1758.

Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opi ...

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.
