Meiocardia Vulgaris
''Meiocardia delicata'' is a species of bivalve in the family Glossidae. Right and left valve of the same specimen: File:Meiocardia vulgaris 01.jpg, Right valve File:Meiocardia vulgaris 02.jpg, Left valve Taxonomy Lovell Augustus Reeve described this species in 1845, placing it in the genus '' Isocardia''. In 1994, S. Kosuge & T. Kase described a junior synonym ''M. delicata''; this was synonymized in 1995 by Akihiko Matsukuma and Tadashige Habe. Reeve gave this species the specific epithet '' vulgaris'' "common" to reflect "the abundant importation of this once rare and highly praised shell." Distribution The type locality of ''M. vulgaris'' and its junior synonym are China and Okinawa, Japan, respectively. Its distribution includes: China, Taiwan, the Philippines, Malaysia, Indonesia, Queensland, Australia, the Andaman Islands, Myanmar Myanmar, ; UK pronunciations: US pronunciations incl. .

Glossus (bivalve)
''Glossus'' is a genus of mostly extinct marine (ocean), marine bivalve molluscs in the family Glossidae. Only the oxheart clam, ''Glossus humanus, G. humanus'', is still Extant taxon, extant, living in flat, muddy regions deep off the North Atlantic coastline of Europe. Fossil records All species of this genus, including the remaining extant species, ''G. humanus'', are found in the fossil record from the Cretaceous to the Pliocene (age range: from 99.7 to 2.588 million years ago). Fossils are found in the marine strata of Eastern North America, Eurasia and the Indo-Pacific. Species The following species and Synonym (taxonomy), synonmised taxa are (or have been) classified under ''Glossus'': * ''Glossus bronni'' * ''Glossus conradi'' Gabb, 1860 (=''Isocarida conradi'') * †''Glossus fraterna'' Say, 1824 * ''Glossus harpa'' * ''Glossus humanus'' (Carl Linnaeus, Linnaeus, 10th edition of Systema Naturae, 1758) * ''Glossus cyprinoides'' * ''Glossus lamarckii'' * ''Glossus lunul ...

Glossus Humanus
''Glossus humanus'', the oxheart clam, is a species of species of marine clam found in deepwater off the Atlantic coastline of Europe and Northern Africa. It is the only remaining extant species in the genus '' Glossus''. Description ''Glossus humanus'' has a shell reaching up to 160 mm in length, but usually it is between 60 and 80 mm. This shell is globular with a subcircular outline. The two valves viewed from the side are heart shaped, forming the outline of a human heart (hence the original species name, ''Cardium humanum''). The walls of the shell are quite thin, equivalve, with a light weight. The outer surface usually is dark brown or olive green, with fine radial lines and frequently covered with short hairs. ''Glossus humanus'' lives half buried into the substratum, exposing only the lower margin of the shell and the siphon. It feeds on plankton and other microscopic particles that it filters out with its gills. Spawning occurs at the end of September. R ...

Umbo (bivalve)
The umbo (plural umbones or umbos) is the vaguely defined, often most prominent, highest part of each valve of the shell of a bivalve or univalve mollusc. It usually contains the valve's beak, the oldest point of the valve, and its degree of prominence and position relative to the hinge line are sometimes helpful in distinguishing bivalve taxa. The umbo forms while the animal is a juvenile, and radial growth subsequently proceeds around that area. The umbo is situated above the hinge line. In those bivalves where the umbones do not protrude, as is the case for example in some mussels, the umbones can nonetheless usually be readily identified by examining the concentric growth lines of the shell. Umbo is also in use in anatomic descriptions of brachiopods, for the origin of growth of the valves. See also * Beak (bivalve) The beak is part of the shell of a bivalve mollusk, i.e. part of the shell of a saltwater or freshwater clam. The beak is the basal projection of the oldest p ...

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 ...

Marine (ocean)
The ocean (also the sea or the world ocean) is the body of salt water that covers approximately 70.8% of the surface of Earth and contains 97% of Earth's water. An ocean can also refer to any of the large bodies of water into which the world ocean is conventionally divided."Ocean." ''Merriam-Webster.com Dictionary'', Merriam-Webster, |
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 ...
