Thracia corbuloidea is a bivalve mollusc in the family Thraciidae. [1]

Family 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 being the "walnut family".

Thraciidae is a taxonomic family of small saltwater clams, marine bivalves in the order Anomalodesmata.

Authority

The name was introduced in Blainville's "Manuel de Malacologie et de Conchyliologie" page 565 (issued 1825), without a description but with reference to plate 76, fig. 7; it only became available when the plate was published in 1827. The same name was introduced again by Blainville (1829) in his article "Thracie" of "Dictionnaire des Sciences Naturelles" (vol. 54, p. 316) with a reference to plate 76, fig. 7 in the Atlas of "Conchyliologie et Malacologie" of the "Dictionnaire", identical to that of the "Manuel". Blainville wrote that the specimen on which the taxon is based belongs to Deshayes' collection, therefore it is presumably an objective synonym of Thracia corbuloidesDeshayes, 1830. [1]

Description

The ovate shell is oblong, transverse, very inequivalve, inequilateral and very much inflated,. It ismarked with irregular lines of increase, entirely white, and covered with a grayish brown epidermis. The beaks of the valves are very large, protuberant and cordiform. The right valve, which is the larger, has its beak notched at its summit to receive the beak of the left valve. The cardinal edge is delicate. It presents upon its posterior side a nympha, which projects within the valves, and which receives a ligament partly internal and partly external. The anterior extremity of the shell is obtuse, rounded. The posterior extremity is truncated : this side is bounded outwardly by a very prominent obtuse angle, which extends obliquely from the beak to the lower part of the shell. Interiorly the valves are white. Two muscular impressions are seen, very much separated, the anterior of which is long and narrow.;The posterior is rounded. They are united by a palleal impression, deeply notched posteriorly. [2]

Distribution

Thracia corbuloidea is found in the North Atlantic Ocean, off Spain, the Azores and the Canary Islands; also off Florida. It is distributed widely round the coasts of Britain where it burrows in sandy or muddy substrates, extending its siphons to the surface to breathe and feed. It is also found in the Mediterranean Sea (Greece, Turkey).

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 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 inequilateral.

Sharpirhynchia sharpi is a species of extinct, small-sized lampshell, named after Samuel Sharp (1814–1882), an early fossil collector, who discovered the limited time span of some fossils, now known as index fossils. S. sharpi is a marine rhynchonellate brachiopod in the family Rhynchonellidae. It is roughly ½ inch (1.25 cm) measured along the axis, with a slender beak, the brachial valve more convex than the pedunculate valve, and it has 21–31 ribs fanning out from the hinge.

Ligament (bivalve)

A hinge ligament is a crucial part of the anatomical structure of a bivalve shell, i.e. the shell of a bivalve mollusk. The shell of a bivalve has two valves and these are joined together by the ligament at the dorsal edge of the shell. The ligament is made of a strong, flexible and elastic, fibrous, proteinaceous material which is usually pale brown, dark brown or black in color.
