Eugeniconus
''Eugeniconus'' is a subgenus of sea snails, marine gastropod mollusks in the genus ''Conus'', family Conidae, the cone snails and their allies. In the latest classification of the family Conidae by Puillandre N., Duda T.F., Meyer C., Olivera B.M. & Bouchet P. (2015), ''Eugeniconus'' has become a subgenus of ''Conus'' as ''Conus (Eugeniconus)'' represented as ''Conus'' Distinguishing characteristics The Tucker & Tenorio 2009 taxonomy distinguishes ''Eugeniconus'' from ''Conus'' in the following ways:Tucker J.K. & Tenorio M.J.

Conidae
Conidae, with the current common name of " cone snails", is a taxonomic family (previously subfamily) of predatory sea snails, marine gastropod molluscs in the superfamily Conoidea. The 2014 classification of the superfamily Conoidea, groups only cone snails in the family Conidae. Some previous classifications grouped the cone snails in a subfamily, Coninae. As of March 2015 Conidae contained over 800 recognized species. Working in 18th-century Europe, Carl Linnaeus knew of only 30 species that are still considered valid. The snails within this family are sophisticated predatory animals. They hunt and immobilize prey using a modified radular tooth along with a venom gland containing neurotoxins; the tooth is launched out of the snail's mouth in a harpoon-like action. Because all cone snails are venomous and capable of "stinging" humans, live ones should be handled with great care or preferably not at all. Current taxonomy In the ''Journal of Molluscan Studies'', in 2014, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Conus
''Conus'' is a genus of predatory sea snails, or cone snails, marine gastropod mollusks in the family Conidae.Bouchet, P.; Gofas, S. (2015). Conus Linnaeus, 1758. In: MolluscaBase (2015). Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=137813 on 2015-11-12 Prior to 2009, cone snail species had all traditionally been grouped into the single genus ''Conus''. However, ''Conus'' is now more precisely defined, and there are several other accepted genera of cone snails. For a list of the currently accepted genera, see Conidae. Description The thick shell of species in the genus ''Conus'' sensu stricto, is obconic, with the whorls enrolled upon themselves. The spire is short, smooth or tuberculated. The narrow aperture is elongated with parallel margins and is truncated at the base. The operculum is very small relative to the size of the shell. It is corneous, narrowly elongated, with an apical nucleus, and the impre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tucker & Tenorio Cone Snail Taxonomy 2009
The taxonomy of the cone snails and their allies as proposed by John K. Tucker and Manuel J. Tenorio in 2009 was a biological classification system for a large group of predatory sea snails. This system was an attempt to make taxonomic sense of the large and diverse group which contains the family Conidae, the cone snails.Tucker J.K. & Tenorio M.J. (2009) Systematic classification of Recent and fossil conoidean gastropods. Hackenheim: Conchbooks. 296 pp., at p. 133 The authors proposed extensive changes to the family Conidae in contrast to the way the group was treated in the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005. Bouchet and Rocroi included in the family Conidae several other groups of toxoglossan snails which had previously been placed in the Turridae. For the over 600 recognized species of living cone snails, Tucker and Tenorio's classification system proposed 3 distinct families and 82 genera. The authors discussed in detail 89 genera and five families in tota ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 ...

Molluscivore
A molluscivore is a carnivorous animal that specialises in feeding on molluscs such as gastropods, bivalves, brachiopods and cephalopods. Known molluscivores include numerous predatory (and often cannibalistic) molluscs, (e.g.octopuses, murexes, decollate snails and oyster drills), arthropods such as crabs and firefly larvae, and, vertebrates such as fish, birds and mammals. Molluscivory is performed in a variety ways with some animals highly adapted to this method of feeding behaviour. A similar behaviour, durophagy, describes the feeding of animals that consume hard-shelled or exoskeleton bearing organisms, such as corals, shelled molluscs, or crabs. Description Molluscivory can be performed in several ways: *In some cases, the mollusc prey are simply swallowed entire, including the shell, whereupon the prey is killed through suffocation and or exposure to digestive enzymes. Only cannibalistic sea slugs, snail-eating cone shells of the taxon Coninae, and some sea anemones ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Indo-Pacific
The Indo-Pacific is a vast biogeographic region of Earth. In a narrow sense, sometimes known as the Indo-West Pacific or Indo-Pacific Asia, it comprises the tropical waters of the Indian Ocean, the western and central Pacific Ocean, and the seas connecting the two in the general area of Indonesia. It does not include the temperate and polar regions of the Indian and Pacific oceans, nor the Tropical Eastern Pacific, along the Pacific coast of the Americas, which is also a distinct marine realm. The term is especially useful in marine biology, ichthyology, and similar fields, since many marine habitats are continuously connected from Madagascar to Japan and Oceania, and a number of species occur over that range, but are not found in the Atlantic Ocean. The region has an exceptionally high species richness, with the world's highest species richness being found in at its heart in the Coral Triangle, and a remarkable gradient of decreasing species richness radiating outwa ...

Radula
The radula (, ; plural radulae or radulas) is an anatomical structure used by molluscs for feeding, sometimes compared to a tongue. It is a minutely toothed, chitinous ribbon, which is typically used for scraping or cutting food before the food enters the esophagus. The radula is unique to the molluscs, and is found in every class of mollusc except the bivalves, which instead use cilia, waving filaments that bring minute organisms to the mouth. Within the gastropods, the radula is used in feeding by both herbivorous and carnivorous snails and slugs. The arrangement of teeth ( denticles) on the radular ribbon varies considerably from one group to another. In most of the more ancient lineages of gastropods, the radula is used to graze, by scraping diatoms and other microscopic algae off rock surfaces and other substrates. Predatory marine snails such as the Naticidae use the radula plus an acidic secretion to bore through the shell of other molluscs. Other predatory marine sn ...

Protoconch
A protoconch (meaning first or earliest or original shell) is an embryonic or larval shell which occurs in some classes of molluscs, e.g., the initial chamber of an ammonite or the larval shell of a gastropod. In older texts it is also called "nucleus". The protoconch may sometimes consist of several whorls, but when this is the case, the whorls show no growth lines. The whorls of the adult shell, which are formed after the protoconch, are known as the teleoconch. The teleoconch starts forming when the larval gastropod becomes a juvenile, and the protoconch may dissolve. Quite often there is a visible line of demarcation where the protoconch ends and the teleoconch begins, and there may be a noticeable change in sculpture, or a sudden appearance of sculpture at that point. In some gastropod groups (such as the Architectonicidae), the teleoconch whorls spiral in the opposite direction to the protoconch. In those cases, the shell is called heterostrophic.
