Rangia (bivalve)
''Rangia'' is a genus of bivalve molluscs or clams in the subfamily Mactrinae of the family Mactridae. Species There are three species: * ''Rangia cuneata'' (G. B. Sowerby I, 1832) – Atlantic rangia * ''Rangia flexuosa'' (Conrad, 1840) – Brown rangia * ''Rangia mendica Rangia may refer to *Rangia or Rangiya Rangia is a city and a municipal board in Kamrup rural district in the Indian state of Assam.

Charles Des Moulins
Charles Des Moulins, full name Charles Robert Alexandre Des Moulins (13 March 1798 – 23 December 1875) was a French naturalist, a botanist and malacologist. He was a member of several learned societies, including the American Philosophical Society, which elected him an international Member in 1861, and the ''Société linnéenne de Bordeaux'', of which he served as its president in 1826. Taxa Moulins named and described numerous species of snails, for example: * '' Pagodulina pagodula'' (Des Moulins, 1830) In turn, in recognition of his services to malacology, a number of species of mollusks were named after him. These latter species included both fossil and recent, both bivalves and gastropods and were mainly non-marine species, however, a few were marine species. Examples as follows: * '' Pisania desmoulinsi'' Montrouzier, 186 a marine gastropod * '' Anodonta desmoulinsiana'' Locard, 188 a freshwater bivalve * '' Nerita desmoulinsiana'' Dautzenberg & Bouge, 1933, a mari ...

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 ...

Mactridae
Mactridae, common name the trough shells or duck clams, is a family of saltwater clams, marine bivalve mollusks in the order Venerida. Description These clams have two short siphons, each with a horny sheath. The shell is shaped like a rounded-cornered equilateral triangle and there is a slight gape at the posterior. Each valve bears two cardinal teeth with four lateral teeth on the right valve and two on the left. The foot is white and wedge-shaped. They mostly inhabit the neritic zone. Ecology Trough shells burrow in sand or fine gravel and never in muddy substrates. Genera According to the World Register of Marine Species (2012), this family contains 37 genera: * '' Anatina'' Schumacher, 1817 * '' Austromactra'' Iredale, 1930 * '' Barymactra'' Cossmann in Cossmann & Peyrot, 1909 * '' Coelomactra'' Dall, 1895 * ''Crassula'' Marwick, 1948 * '' Cyclomactra'' Dall, 1895 * '' Darina'' Gray, 1853 * '' Diaphoromactra'' Iredale, 1930 * '' Eastonia'' Gray, 1853 * '' Harvella'' G ...

Rangia Cuneata
''Rangia cuneata'' or Atlantic rangia, also known as wedge clam, gulf wedge clam, common rangia, and cocktail clam, is a mollusc native to Gulf of Mexico. It is an oval clam with body length of up to 5cm, living form the intertidal zone to depths of 124 meters. It is edible and is harvested for food in Mexico, and has been so since pre-Hispanic times. Invasive species Atlantic rangia have been introduced to US North Atlantic coast, Belgium ( Antwerp) and the Baltic sea The Baltic Sea is an arm of the Atlantic Ocean that is enclosed by Denmark, Estonia, Finland, Germany, Latvia, Lithuania, Poland, Russia, Sweden and the North and Central European Plain.
