Oenopotinae
Oenopotinae is a subfamily of small to medium-sized sea snails, marine gastropod mollusks in the family Conidae.Bouchet P. & Rocroi J.-P. (Ed.) (2005). "Classification and nomenclator of gastropod families". '' Malacologia'' 47(1-2). . 397 pp. This subfamily was introduced by Bogdanov in 1987. In 2014 this subfamily has been included in the family Mangeliidae Description The Oenopotinae are characterized by a thin, elongate-ovate to fusiform shell in the form of a tall spire with a size between 4.7mm and 24.5 mm. They show a present, vestigial or absent operculum and a shallow or inconspicuous sinus. This outer lip (labrum) is thin. The axial ribs are dominant in the sculpture of the shell. The toxoglossate radula has a weak basal ribbon and relatively short marginal teeth with solid base. The tooth cavity opens laterally between the shaft and the base.

Conoidea
Conoidea is a superfamily of predatory sea snails, marine gastropod mollusks within the suborder Hypsogastropoda. This superfamily is a very large group of marine mollusks, estimated at about 340 recent valid genera and subgenera, and considered by one authority to contain 4,000 named living species. This superfamily includes the turrids, the terebras (also known as auger snails or auger shells) and the cones or cone snails. The phylogenetic relationships within this superfamily are poorly established. Several families (especially the Turridae), subfamilies and genera are thought to be polyphyletic. In contrast to Puillandre's estimate, Bandyopadhyay et al. (2008) estimated that the superfamily Conoidea contains about 10,000 species. Tucker (2004) even speaks of 11,350 species in the group of taxa commonly referred to as turrids.Tucker, J.K. 2004 ''Catalog of recent and fossil turrids (Mollusca: Gastropoda).'' Zootaxa 682:1–1295. 3000 recent taxa are potentially valid specie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.

Mangeliidae
Mangeliidae is a monophyletic family of small to medium-sized, predatory sea snails, marine gastropod mollusks in the superfamily Conoidea. Bouchet, P. (2011). Mangeliidae P. Fischer, 1883. In: MolluscaBase (2016). Accessed through: World Register of Marine Species at http://marinespecies.org/aphia.php?p=taxdetails&id=153853 on 2017-02-23Bouchet P. & Rocroi J.-P. (Ed.) (2005). "Classification and nomenclator of gastropod families". ''Malacologia'' 47(1-2). . 397 pp. Prior to 2011, both the subfamilies Mangeliinae and Oenopotinae had been placed in the family Conidae. In 2011, Bouchet, Kantor ''et al'' merged the two subfamilies into one taxon, which they elevated to the rank of family. This was based on anatomical characters and a dataset of molecular sequences of three gene fragments. Mangeliidae is a sister-clade to the family Raphitomidae As with their relatives in the family Conidae, species in the family Mangelidae use potent venoms to catch their prey. Through this cha ...

Oenopota
''Oenopota'' is a genus of sea snails, marine gastropod mollusks in the family Mangeliidae. This genus doesn't form a monophyletic group. Therefore many species are only tentatively placed within this genus. Description In 1941 Paul Bartsch described species in this genus as having large, heavy and elongate -ovate to elongate- turreted shells. The protoconch is smooth at the apex, succeeded by a whorl with three spiral cords and rather distantly spaced axial ribs. The longitudinal ribs become stronger on succeeding whorls but evanesce at the base of the shell. The spiral sculpture weakens on succeeding whorls and finally becomes mere threads. The pear-shaped aperture is deeply channeled anteriorly. It shows in the outer lip near the summit a feeble posterior sinus. Later, in 1980, it has been stated by Bouchet & Warèn that there is a high variation within the arctic forms of this genus, such as the outer lip showing all transitions from sinuated to nonsinuated Distribut ...

Operculum (gastropod)
The operculum (; ) is a corneous or calcareous anatomical structure like a trapdoor that exists in many (but not all) groups of sea snails and freshwater snails, and also in a few groups of land snails; the structure is found in some marine and freshwater gastropods, and in a minority of terrestrial gastropods, including the families Helicinidae, Cyclophoridae, Aciculidae, Maizaniidae, Pomatiidae, etc. The operculum is attached to the upper surface of the foot and in its most complete state, it serves as a sort of "trapdoor" to close the aperture of the shell when the soft parts of the animal are retracted. The shape of the operculum varies greatly from one family of gastropods to another. It is fairly often circular, or more or less oval in shape. In species where the operculum fits snugly, its outline corresponds exactly to the shape of the aperture of the shell and it serves to seal the entrance of the shell. Many families have opercula that are reduced in size, and which a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Curtitoma
''Curtitoma'' is a genus of sea snails, marine gastropod mollusks in the family Mangeliidae. Description This genus was introduced by Paul Bartsch in 1941 to accommodate species with a distinct anal sinus and a protoconch sculptured with numerous fine threads, that were otherwise similar to the species in the genera ''Oenopota'' Moerch, 1852 and ''Propebela'' Iredale, 1918. The shell has an ovoid shape and is short and stubby. The whorls of the teleoconch are strongly tabulatedly shouldered and lack a keel at the angulation of the shoulder. The axial ribs show up strongly between the shoulder and the periphery, but disappear at the base of the shell. The spiral sculpture consists of incised lines on the spire and threads on the columella. The aperture is pear-shaped, decidedly channeled anteriorly and shows a feeble sinus at the shoulder. Grammatical gender The grammatical gender is feminine, as composed with the Greek noun τομή, an incision (gender: feminine). However often ...

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 snails ...
