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 ...

Turrid
Turrid, plural turrids, is a common name for a very large group of predatory sea snails, marine gastropod mollusks which until recently were all classified in the family Turridae. However, recently the family was discovered to be polyphyletic and therefore was split into a number of families. The original family Turridae used to contain more than 4,000 species.Des Beechey (2003)Family Turridae. Turrids.Accessed 30 November 2007. the Turridae (''sensu'' Powell 1966) It was the largest mollusk family and the largest group of marine caenogastropods. There were approximately 27,000 described scientific names (accepted names plus synonyms) within the family Turridae. Turrids constituted more than half of the predatory species of gastropods in some parts of the world (Taylor et al. 1980). However, this very large family was shown to be polyphyletic, and in 2011 it was divided into 13 separate families by Bouchet, Kantor, Sysoev and Puilandre. The single most complete collection o ...

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).''

Turris
''Turris'' is a genus of sea snails, marine gastropod mollusks in the family Turridae, the turrids. Description The generally large shells are variegated with spots. The fusiform shell is turriculated with a long, sharp spire. The aperture is ovate. The columellar lip is smooth. The outer lip is separated with a narrow profound sinus from the suture rather than distantly. The siphonal canal is long and narrow, straight and open.George Washington Tryon, Manual of Conchology VI, p. 160; 1884 (Description by Charles Hedley) The shell is large, with a tall slender spire. The outer lip is sharp, without fold or thickening. The siphonal notch is a deep slit with parallel sides following a walled-in fasciole. Within the body whorl are sharp raised revolving threads, a feature shared by related genera. The protoconch consists of two smooth rounded whorls. The operculum is unguiculate, with an apical nucleus. The foot of the animal is anteriorly truncated but obtuse posteriorly. T ...

Crassispirinae
Pseudomelatomidae is a family of predatory sea snails, marine gastropods included in the superfamily Conoidea (previously Conacea) and part of the Neogastropoda ( Bouchet & Rocroi, 2005). In 1995 Kantor elevated the subfamily Pseudomelatominae to the status of family Pseudomelatomidae. In 2011 Bouchet, Kantor ''et al''. moved the Crassispirinae and Zonulispirinae and numerous genera of snails loosely called turrid snails (which at that point had been placed in the family Conidae) and placed them in the family Pseudomelatomidae. This was based on a cladistical analysis of shell morphology, radular characteristics, anatomical characters, and a dataset of molecular sequences of three gene fragments.

Taxonomy Of The Gastropoda (Bouchet & Rocroi, 2005)
The taxonomy of the Gastropoda as it was revised in 2005 by Philippe Bouchet and Jean-Pierre Rocroi is a system for the scientific classification of gastropod mollusks. (Gastropods are a taxonomic class of animals which consists of snails and slugs of every kind, from the land, from freshwater, and from saltwater.) The paper setting out this taxonomy was published in the journal '' Malacologia''. The system encompasses both living and extinct groups, as well as some fossils whose classification as gastropods is uncertain. The Bouchet & Rocroi system was the first complete gastropod taxonomy that primarily employed the concept of clades, and was derived from research on molecular phylogenetics; in this context a clade is a "natural grouping" of organisms based upon a statistical cluster analysis. In contrast, most of the previous overall taxonomic schemes for gastropods relied on morphological features to classify these animals, and used taxon ranks such as order, superorder an ...

Anal Sinus (gastropod)
The anal sulcus, also called the anal sinus or anal canal, in Gastropods is a notch, a shelly tube at the top of the aperture In optics, an aperture is a hole or an opening through which light travels. More specifically, the aperture and focal length of an optical system determine the cone angle of a bundle of rays that come to a focus in the image plane. An .... It is the first notch close to the suture. It houses the anal siphon through which the snail expels water and waste products. The anal sulcus can be described, according to the species, as well-defined, weakly defined, shallow, sharp, wide, narrow or inverted U-shaped. In some species, such as in the Murex family, the anal sulcus is absent. The anal sulcus can be linked on the edges to a fasciole, a spiral band on the shell, formed by successive growth lines. It can also have a subsutural callus (such as in Clathrodrillia callianira). References Gastropod anatomy Mollusc shells {{gastropod-stub ...

Arthur Adams (zoologist)
Arthur Adams (1820 in Gosport, Hampshire – 1878) was an English physician and naturalist. Adams was assistant surgeon Royal Navy on board HMS ''Samarang'' during the survey of the islands of the Eastern Archipelago, from 1843 to 1846. He edited the ''Zoology of the voyage of H.M.S. Samarang'' (1850). Adam White collaborated with him in the descriptions of the Crustacea from the voyage. In 1857, during the Second China War whilst serving as Surgeon on HMS ''Actaeon'', he was present at the storming of Canton and awarded the China War Medal. He retired as Staff Surgeon aboard flagship HMS ''Royal Adelaide'' at Plymouth in 1870.
