Zonulispirinae
Pseudomelatomidae is a family (biology), family of predatory sea snails, marine gastropods included in the superfamily Conoidea (previously Conacea) and part of the Neogastropoda (Taxonomy of the Gastropoda (Bouchet & Rocroi, 2005), Bouchet & Rocroi, 2005). In 1995 Kantor elevated the subfamily Pseudomelatominae to the status of family Pseudomelatomidae. In 2011 Philippe Bouchet, Bouchet, Kantor ''et al''. moved the Crassispirinae and Zonulispirinae and numerous genera of snails loosely called Turridae, 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 (biology), morphology, radula, radular characteristics, anatomical characters, and a dataset of molecular sequences of three gene fragments. Genera Genera within the family Pseudomelatomidae include: * ''Abyssocomitas'' Sysoev & Kantor, 1986 * ''Aguilaria'' Taylor & Wells, 1994 * ''Anticomitas ...

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 ...

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).''

Gastropod Shell
The gastropod shell is part of the body of a Gastropoda, gastropod or snail, a kind of mollusc. The shell is an exoskeleton, which protects from predators, mechanical damage, and dehydration, but also serves for muscle attachment and calcium storage. Some gastropods appear shell-less (slugs) but may have a remnant within the mantle, or in some cases the shell is reduced such that the body cannot be retracted within it (semi-slug). Some snails also possess an operculum that seals the opening of the shell, known as the Aperture (mollusc), aperture, which provides further protection. The study of mollusc shells is known as conchology. The biological study of gastropods, and other molluscs in general, is malacology. Shell morphology terms vary by species group. Shell layers The gastropod shell has three major layers secreted by the Mantle (mollusc), mantle. The calcareous central layer, tracum, is typically made of calcium carbonate precipitated into an organic matrix known as c ...

Aguilaria
''Aguilaria subochracea'' is a species of sea snailin the family Pseudomelatomidae. It is the only species in the genus ''Aguilaria''. Description The length of the shell attains 39 mm, its diameter 11 mm. The elongate, fusiform, turreted shell is very characteristically coloured. The reddish-ochre colour is uniform, except where the transverse lirations (5 in the penultimate whorl and about 22 in the body whorl) cross the ribs or plications (14 in the body whorl), where they are white and slightly nodulous. The suture is well defined by the sudden termination of the ribs. The shell contains 13 convex whorls that are set back at the top. The aperture has a flesh colour. It is ovate at the top and ends in a mediocre elongated and recurved siphonal canal. It measures about 3/7 of the total length. The outer lip is rather incrassate and sinuate in the excavation. The columella is twisted, callous and shows a small tubercle at the top. Distribution This species occurs in t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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] |
