Noetiidae
Noetiidae is a family of saltwater clams, marine bivalve molluscs in the order Arcida. They are related to the ark clams and used to be classified as among them. They are differentiated from the ark clams by the presence of striations on the hinge ligament A ligament is the fibrous connective tissue that connects bones to other bones. It is also known as ''articular ligament'', ''articular larua'', ''fibrous ligament'', or ''true ligament''. Other ligaments in the body include the: * Peritoneal li ... and on the placement of this ligament. Like the ark clams, however, their shells range from ovate to elongate, are inflated, and are brown and white with clear radial ribs. They usually grow to around 6 cm in length, with a maximum of 10 cm. Genera and species Genera and species within the family Noetidae include: * '' Arcopsis'' Koenen, 1885 ** ''Arcopsis adamsi'' (Dall, 1886) ** ''Arcopsis fossularca'' ** ''Arcopsis gabinarca'' ** ''Arcopsis mulinarca'' ** ''Arcopsis ...

Arcida
The Arcida is an extant order of bivalve molluscs. This order dates back to the lower Ordovician period. They are distinguished from related groups, such as the mussels, by having a straight hinge to the shells, and the adductor muscles being of equal size. The duplivincular ligament, taxodont dentition, and a shell microstructure consisting of the outer crossed lamellar and inner complex crossed lamellar layers are defining characters of this order. Seven families are currently recognised within the order, including the well-known ark clams or ark shells in the family Arcidae. Taxonomy The order Arcida, as the suborder Arcacea, is included in the order Taxodonta by R.C. Moore, 1952,R.C, Moore, Pelecypods, Ch 10, Inverrtebrate Fossils, Moore, Lalicker, and Fischer. McGraw-Hill, 1952. characterised by simple hinge-line dentition consisting of small, numerous, similar hinge teeth, separate mantle lobes, poorly developed siphons, and filibranch gills.

Bivalve Shell
A bivalve shell is part of the body, the exoskeleton or shell, of a bivalve mollusk. In life, the shell of this class of mollusks is composed of two hinged parts or ''valves''. Bivalves are very common in essentially all aquatic locales, including saltwater, brackish water, and freshwater. The shells of bivalves commonly wash up on beaches (often as separate valves) and along the edges of lakes, rivers, and streams. Bivalves by definition possess two shells or ''valves'', a "right valve" and a "left valve", that are joined by a ligament. The two valves usually articulate with one another using structures known as "teeth" which are situated along the hinge line. In many bivalve shells, the two valves are symmetrical along the hinge line—when truly symmetrical, such an animal is said to be ''equivalved''; if the valves vary from each other in size or shape, ''inequivalved''. If symmetrical front-to-back, the valves are said to be ''equilateral'', and are otherwise considered ''in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...

Striation
{{disambiguation ...
Striations means a series of ridges, furrows or linear marks, and is used in several ways: * Glacial striation * Striation (fatigue), in material * Striation (geology), a ''striation'' as a result of a geological fault * Striation Valley, in Antarctica * In hyperbolic geometry, a ''striation'' is a reflection across two parallel mirrors. * In anatomy, striated muscle * Striations can be found in certain glasses. These have been caused by turbulent flow during teeming (pouring) of the glass. * Striations can be observed in clouds. See Barber's pole. * Ballistic fingerprinting Forensic firearm examination is the forensic process of examining the characteristics of firearms or bullets left behind at a crime scene. Specialists in this field try to link bullets to weapons and weapons to individuals. They can raise and re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
