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.
Harpa, common name the "harp snails", is a genus of large predatory sea snails, marine gastropod mollusks in the family Harpidae.
Laternulidae, common name lantern clams, is a family of saltwater clams, marine bivalve molluscs in the order Anomalodesmata.
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.
The grooved carpet shell, or Palourde clam, Ruditapes decussatus, or Venerupis decussatus, is a clam in the family Veneridae. It is distributed worldwide and due to its ecological and economic interest has been proposed as a bioindicator.
Tritia pygmaea is a species of sea snail, a marine gastropod mollusk in the family Nassariidae, the nassa mud snails or dog whelks.
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.
Lutraria is a genus of medium-sized marine bivalve mollusks or clams, commonly known as otter shells.
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 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.
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.
