Thracia corbuloidea is a bivalve mollusc in the family Thraciidae.
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.
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.
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.
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).
Henri Marie Ducrotay de Blainville was a French zoologist and anatomist.
Gérard Paul Deshayes was a French geologist and conchologist.
The Veneridae or venerids, common name: venus clams, are a very large family of minute to large, saltwater clams, marine bivalve molluscs. Over 500 living species of venerid bivalves are known, most of which are edible, and many of which are exploited as food sources.
The greater wing of the sphenoid bone, or alisphenoid, is a bony process of the sphenoid bone; there is one on each side, extending from the side of the body of the sphenoid and curving upward, laterally, and backward.
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.
Pleurobranchaea meckeli is a species of sea slug, specifically a side gill slug or notaspideans. It is a marine gastropod mollusc in the family Pleurobranchaeidae.
Ficus is a genus of large sea snails, marine gastropod mollusks in the family Ficidae, the fig shells.
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.
Rhynchonelloidella alemanica is a species of extinct, small-sized brachiopod, a marine rhynchonellate lampshell in the family Rhynchonellidae. It is roughly 9/16 inch (1.4 cm), and has about 15 ribs fanning out from the hinge.
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.
Thracia is a genus of bivalve mollusc in the family Thraciidae.
Thracia pubescens is a bivalve mollusc in the family Thraciidae.
Cyathodonta plicata is a bivalve mollusc in the family Thraciidae.
Thracia phaseolina is a bivalve mollusc in the family Thraciidae.
Fusconaia burkei is a species of freshwater mussel, an aquatic bivalve mollusk in the family Unionidae, the river mussels.
Halongella schlumbergeri is a species of air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Plectopylidae.
Coriocella nigra is a species of sea snail, a marine gastropod mollusk in the family Velutinidae. An Indo-Pacific species, it lives on rocks at depths of up to 15 m. It is up to 10 cm long and has an internal shell; body color is black or brown. C. nigra is probably a predator of tunicates.
Nassodonta dorri is a species of brackish water snail, with gills and an operculum, a gastropod mollusk in the family Nassariidae, the nassa mud snails or dog whelks.
