Thracia phaseolina is a bivalve mollusc in the family Thraciidae. [1]
The ovate shell is oblong, transverse, equilateral and inequivalve. The beaks are small; that of the left, slightly notched. The valves are white, diaphanous and smooth, indistinctly marked with striae of increase, rounded at the anterior side, strongly truncated at the posterior side. The side is bounded outwardly by an obtuse angle, pretty prominent, extending obliquely from the beak to the lower part of the shell. The cardinal edge is thin, and without teeth. It presents upon the posterior side the beaks with a small, internal, short, triangular hollow, in which is attached a small internal ligament which is apparent externally. The valves are white and shining, internally. The anterior muscular impression is elongated, the posterior is rounded, and is united to the anterior by a pallial impression, deeply notched. [2]

Thracia phaseolina is found in the North Atlantic Ocean and in the North Sea It is also found in the Mediterranean Sea and in the Gulf of Mexico.
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.
Laternulidae, common name lantern clams, is a family of saltwater clams, marine bivalve molluscs in the order Anomalodesmata.
A bivalve shell is the enveloping exoskeleton or shell of a bivalve mollusc, composed of two hinged halves or valves. The two half-shells, called the "right valve" and "left valve", are joined by a ligament and 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.
The grooved carpet shell, or Palourde clam, Ruditapes decussatus, or Venerupis decussatus, is a clam in the family Veneridae. It is distributed worldwide and is highly prized due to its ecological and economic interest. It has been proposed as a bioindicator.
Petricolaria pholadiformis, common names false angelwing, or false angel wing (US), and American piddock (UK), is a species of saltwater clam, a marine bivalve mollusk in the family Veneridae, the Venus clams.
Fabulina fabula, the bean-like tellin, is a species of marine bivalve mollusc in the family Tellinidae. It is found off the coasts of northwest Europe, where it lives buried in sandy sediments.
Tellimya ferruginosa is a species of small marine bivalve mollusc in the family Lasaeidae. It is found on the eastern side of the Atlantic Ocean.
Phaxas pellucidus, the transparent razor shell, is a species of marine bivalve mollusc in the family Pharidae. It is found buried in the seabed in coastal waters of northwest Europe, often in great numbers.
Venerupis is a genus of marine bivalve molluscs in the family Veneridae commonly known as carpet shells. The valves are robust and rhomboidal with the umbones turned-in and nearer the anterior end. The posterior end is wedge-shaped and the internal margins of the valves are smooth. There are 3 or 4 cardinal teeth on each valve. The foot is large and the siphons are of medium length and united except at the very tip.
Thracia convexa is a bivalve mollusc in the family Thraciidae.
Mulinia lateralis, the dwarf surf clam or coot clam, is a species of small saltwater clam, a bivalve mollusc in the family Mactridae. It occurs in the western Atlantic Ocean and the Caribbean Sea.
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 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.
Solemya elarraichensis is a species of marine bivalve mollusc in the family Solemyidae. It is endemic to the deep-water mud volcano slopes in the Gulf of Cadiz in the eastern Atlantic Ocean.

Thracia corbuloidea is a 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.
Polititapes aureus is a species of bivalve belonging to the family Veneridae.
Lucinella divaricata, the divaricate lucine, is a small marine bivalve mollusc of the family Lucinidae found in the north eastern Atlantic and the Mediterranean. Its fossils are known from Cenozoic deposits all over Europe. Chemoautotrophic bacteria in their gills enable them to survive well in substrates rich in hydrogen sulfide.
