Ascetoaxinus Quatsinoensis
''Ascetoaxinus quatsinoensis'' is a species of saltwater clam, a bivalve mollusc in the family Thyasiridae. The shell of this species is unusual in that it has a lunule with scalloped edges. The species was first described by Graham Oliver of the National Museum of Wales and Melissa Frey, curator of invertebrates at the Royal BC Museum. The type specimen acquired by the Royal BC Museum was collected from Quatsino Sound, Vancouver Island Vancouver Island is an island in the northeastern Pacific Ocean and part of the Canadian Provinces and territories of Canada, province of British Columbia. The island is in length, in width at its widest point, and in total area, while are o ..., British Columbia, Canada.

Lunule (bivalve)
A lunule (from the Latin meaning small moon or crescent moon) is an anatomical feature which is found in the exterior surface of the shells of some species of clams, bivalve mollusc, mollusks, as for example in the family Veneridae and in the genus ''Ascetoaxinus''. The lunule is a well-defined area near the hinge line of the shell, anterior to the beaks. Website conchs.org, The Conchological Society of Great Britain and Ireland, Molluscs, Glossary, Advanced glossary of molluscan terminology, Lunule, by Steve Wilkinson, 5 November 201Accessed 2014.12.9 Despite the name, a lunule is not always in the shape of a crescent moon. Details of the lunule are sometimes an important diagnostic feature in identifying a bivalve shell. References {{Bivalve anatomy Bivalve anatomy Mollusc shells ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Bivalve
Bivalvia (), in previous centuries referred to as the Lamellibranchiata and Pelecypoda, is a class of marine and freshwater molluscs that have laterally compressed bodies enclosed by a shell consisting of two hinged parts. As a group, bivalves have no head and they lack some usual molluscan organs, like the radula and the odontophore. They include the clams, oysters, cockles, mussels, scallops, and numerous other families that live in saltwater, as well as a number of families that live in freshwater. The majority are filter feeders. The gills have evolved into ctenidia, specialised organs for feeding and breathing. Most bivalves bury themselves in sediment, where they are relatively safe from predation. Others lie on the sea floor or attach themselves to rocks or other hard surfaces. Some bivalves, such as the scallops and file shells, can swim. The shipworms bore into wood, clay, or stone and live inside these substances. The shell of a bivalve is composed of calc ...

Mollusc
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. The gastropods ... [...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 ...

Royal British Columbia Museum
Founded in 1886, the Royal British Columbia Museum (sometimes referred to as Royal BC Museum) consists of The Province of British Columbia's natural and human history museum as well as the British Columbia Provincial Archives. The museum is located in Victoria, British Columbia, Canada. The "Royal" title was approved by Queen Elizabeth II and bestowed by HRH Prince Philip in 1987, to coincide with a Royal tour of that year. The museum merged with the British Columbia Provincial Archives in 2003. The Royal BC Museum includes three permanent galleries: Natural History, Becoming BC, and the First Peoples Gallery. The museum's collections comprise approximately 7 million objects, including natural history specimens, artifacts, and archival records.2010-11 Annual Report, p. 40 The natural history collections have 750,000 records of specimens almost exclusively from BC and neighbouring states, provinces, or territories. The collections are divided into eight disciplines: Entomology, B ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
