Pectinidae
Scallop () is a common name that encompasses various species of Marine (ocean), marine bivalve mollusc, molluscs in the Taxonomy (biology), taxonomic Family (biology), 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. Scallops are a Cosmopolitan distribution, cosmopolitan family of bivalves found in all of the world's oceans, although never in fresh water. They are one of the very few groups of bivalves to be primarily "free-living", with many species capable of rapidly swimming short distances and even migrating some distance across the ocean floor. A small minority of scallop species live cemented to rocky substrate (biology), substrates as adults, while others attach themselves to stationary or rooted objects such as seagrass at some point in their lives by means of a filament they secrete called a byssal thread. ...

Pectinoidea
The Pectinoidea are a Taxonomic rank, superfamily of marine (ocean), marine bivalve molluscs, including the scallops and spiny oysters.Gofas, S. (2012). Pectinoidea. Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=151320 on 2012-07-08 Shell anatomy All members of this superfamily have a triangular resilium with a nonmineralized medial core that functions below the hinge line. Families According to the World Register of Marine Species, the Pectinoidea include these families (all taxa marked † are extinct): * Cyclochlamydidae * Entoliidae * Neitheidae † * Pectinidae (scallops) * Pleuronectitidae † * Propeamussiidae some are known as glass scallops * Spondylidae thorny oysters * Tosapectinidae † ;Families brought into synonymy: * Propeamussidae: synonym of Propeamussiidae * Syncyclonematidae: synonym of Entoliidae References * Raines, B.

Argopecten Irradians
''Argopecten irradians'', formerly classified as '' Aequipecten irradians'', common names Atlantic bay scallop, bay scallop, and blue-eyed scallop, is a species of scallop in the family Pectinidae. An edible saltwater clam, it is native to the northwest Atlantic from Cape Cod to the Gulf of Mexico.

At the southern extreme the timeline is very different, with cytoplasmic growth stages found to occur in July in Tarpon Springs, Florida, when the water approaches its highest temperatures of the year.
