Conorbiinae
Conorbiinae was a subfamily of small to quite large 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 has also been written by several authors as "Conorbinae". ( and was a long time considered a subfamily of the Turridae. Bouchet, Kantor ''et al''. elevated in 2011 the subfamily Conorbiinae to the rank of family Conorbidae. This was based on anatomical characters ( radular tooth and shell characters) and a dataset of molecular sequences of three gene fragments Genera Genera in the subfamily Conorbiinae include : *'' Benthofascis'' Iredale, 1936 *''Conorbis ''Conorbis'' is an extinct genus of sea snails, marine gastropod mollusks in the family Conorbidae.

Conorbidae

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.

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).''

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.

(2009) ''Systematic classification of Recent and fossil conoidean gastropods''. Hackenheim: Conchbooks. 296 pp., at pp. 134–135.)

This genus was previously included in the family Turridae (subfamily Conorbinae) and later in the family Conidae. In 2009 Tucker & Tenorio included it in the family Conorbidae.Tucker, J.K. & Tenorio, M.J.

Gene
In biology, the word gene (from , ; "...Wilhelm Johannsen coined the word gene to describe the Mendelian units of heredity..." meaning ''generation'' or ''birth'' or ''gender'') can have several different meanings. The Mendelian gene is a basic unit of heredity and the molecular gene is a sequence of nucleotides in DNA that is transcribed to produce a functional RNA. There are two types of molecular genes: protein-coding genes and noncoding genes. During gene expression, the DNA is first copied into RNA. The RNA can be directly functional or be the intermediate template for a protein that performs a function. The transmission of genes to an organism's offspring is the basis of the inheritance of phenotypic traits. These genes make up different DNA sequences called genotypes. Genotypes along with environmental and developmental factors determine what the phenotypes will be. Most biological traits are under the influence of polygenes (many different genes) as well as gen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Philippe Bouchet
Philippe Bouchet (born 1953) is a French biologist whose primary scientific fields of study are malacology (the study of molluscs) and taxonomy. He works at the Muséum National d'Histoire Naturelle in Paris. He is also a Commissioner of the International Commission on Zoological Nomenclature. Bouchet published Taxonomy of the Gastropoda with the malacologist Jean-Pierre Rocroi in 2005, which laid out a new taxonomy of Gastropod molluscs. He has named over 500 new taxa of mollusks, and numerous taxa have been named in his honor. Professional achievements Bouchet is a senior professor at the Muséum National d'Histoire Naturelle in Paris, and is head of the Malacology laboratory and the Taxonomy Collections Unit there. He is also one of the Commissioners of the International Commission on Zoological Nomenclature and has been a member of the ICZN since 1990. Philippe Bouchet is co-editor of several volumes in the Tropical Deep-Sea Benthos series. In 2005, Bouchet was the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Turridae
Turridae is a taxonomic family name for a number of predatory sea snails, marine gastropod mollusks in the superfamily Conoidea. MolluscaBase (2018). Turridae H. Adams & A. Adams, 1853 (1838). Accessed through: World Register of Marine Species at: http://www.marinespecies.org/aphia.php?p=taxdetails&id=152 on 2018-07-22 The family name Turridae was originally given to a very large group of several thousand sea snail species that were thought to be closely related. The family was described with about 700 genus-group taxa and an estimated 10,000 recent and fossil species. However, that original grouping was discovered to be polyphyletic. In recent years, the family Turridae has been much reduced in size, because a number of other families were created to contain the monophyletic lineages that had previously been thought to belong in the same family. The common name ''turrids'' is still used informally to refer to the polyphyletic group. Distribution Species in the family ...
