Clam is a common name for several kinds of bivalve mollusc. The word is often applied only to those that are edible and live as infauna, spending most of their lives halfway buried in the sand of the sea floor or riverbeds. Clams have two shells of equal size connected by two adductor muscles and have a powerful burrowing foot. They live in both freshwater and marine environments; in salt water they prefer to burrow down into the mud and the turbidity of the water required varies with species and location; the greatest diversity of these is in North America.
Bivalvia or bivalves, in previous centuries referred to as the Lamellibranchiata and Pelecypoda, is a class of aquatic molluscs that have laterally compressed soft bodies enclosed by a calcified exoskeleton consisting of a hinged pair of half-shells known as valves. As a group, bivalves have no head and lack some typical molluscan organs such as the radula and the odontophore. Their gills have evolved into ctenidia, specialised organs for feeding and breathing.
Scallop is a common name that encompasses various species of marine bivalve mollusks in the taxonomic family Pectinidae, the scallops. However, the common name "scallop" is also sometimes applied to species in other closely related families within the superfamily Pectinoidea, which also includes the thorny oysters.
Argopecten gibbus, the Atlantic calico scallop, is a species of medium-sized edible marine bivalve mollusk in the family Pectinidae, the scallops.
The queen scallop is a medium-sized species of scallop, an edible marine bivalve mollusk in the family Pectinidae, the scallops. It is found in the northeast Atlantic and is important in fisheries.
Aequipecten is a genus of scallops, marine bivalve mollusks in the family Pectinidae.
Pecten novaezelandiae, common name the New Zealand scallop, is a bivalve mollusc of the family Pectinidae, the scallops. Its name is sometimes found misspelt as Pecten novaezealandiae.
Chamelea gallina is a species of small saltwater clam, a marine bivalve in the family Veneridae, the venus clams.
Pecten maximus, common names the great scallop, king scallop, St James shell or escallop, is a northeast Atlantic species of scallop, an edible saltwater clam, a marine bivalve mollusc in the family Pectinidae. This is the type species of the genus. This species may be conspecific with Pecten jacobaeus, the pilgrim's scallop, which has a much more restricted distribution.
Argopecten is a genus of saltwater clams, or scallops, marine bivalve mollusks in the family Pectinidae.

Scallop aquaculture is the commercial activity of cultivating (farming) scallops until they reach a marketable size and can be sold as a consumer product. Wild juvenile scallops, or spat, were collected for growing in Japan as early as 1934. The first attempts to fully cultivate scallops in farm environments were not recorded until the 1950s and 1960s. Traditionally, fishing for wild scallops has been the preferred practice, since farming can be expensive. However worldwide declines in wild scallop populations have resulted in the growth of aquaculture. Globally the scallop aquaculture industry is now well established, with a reported annual production totalling over 1,200,000 metric tonnes from about 12 species. China and Japan account for about 90% of the reported production.
Mizuhopecten yessoensis is a species of marine bivalve mollusks in the family Pectinidae, the scallops. Its name Yesso/Ezo refers to its being found north of Japan.
Tumidotheres maculatus is a species of crab that lives commensally or parasitically in the mantle cavity of molluscs. It is found along much of the western Atlantic Ocean and was first described by Thomas Say in 1818.
Nodipecten nodosus, or the lion's paw scallop, is a species of bivalve mollusc in the family Pectinidae. It can be found along the Atlantic coast of North America, ranging from Cape Hatteras to the West Indies, including Brazil and Bermuda.
The Antarctic scallop is a species of bivalve mollusc in the large family of scallops, the Pectinidae. It was thought to be the only species in the genus Adamussium until an extinct Pliocene species was described in 2016. Its exact relationship to other members of the Pectinidae is unclear. It is found in the ice-cold seas surrounding Antarctica, sometimes at great depths.
The Maria Mitchell Association Aquarium, also known as the Nantucket Aquarium, is a small, local, seasonal aquarium in Nantucket, Massachusetts. It serves as the island's only marine science center and resource. The Aquarium is one of the many resources offered by the Maria Mitchell Association, a local non-profit organization that promotes scientific education and research in service to the legacy of Maria Mitchell (1818-1889), America's first female astronomer and Nantucket native.
Diopatra cuprea, commonly known as the plumed worm, decorator worm or sometimes ornate worm, is a species of polychaete worm in the family Onuphidae, first described by the French entomologist Louis Augustin Guillaume Bosc in 1802. It is native to the northwestern Atlantic Ocean, the Caribbean Sea and the Gulf of Mexico.
Peconic Bay scallops are a population of northern bay scallops found in the Peconic Bays of eastern Long Island. They are known as a regional culinary specialty and an important part of aquaculture in New York. The history of harvesting Peconic Bay scallops has been dated to the Late Woodland period, 1,000 to 1,500 years ago.
