Pecten excavatus is a species of scallop, marine bivalve molluscs in the taxonomic family Pectinidae.
In this species, the valves are greatly inequal and plano-convex in shape: the right valve is highly convex, and the left valve is correspondingly concave, an arrangement unusual within the scallop family. The valves are front-back symmetrical, however, and the ears are equal, convex, and rectangularly truncated. [1]
It can be distinguished from the very similar species Pecten albicans by the number of ribs present on either valve. P. albicans has in the range of seven to ten ribs with a mode of eight, while those of P. excavatus range from eight to eleven or more with an average number of ten. [2]
This scallop prefers to inhabit fine, sandy bottoms 10-80 meters below the surface. [3] This species is found in eastern Asia. [4]
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.
Chesapecten is an extinct genus of scallop known from marine strata from the early Miocene to the early Pleistocene of the Eastern United States.

Propeamussiidae, sometimes referred to as glass scallopsmud scallops or mud pectens, are a taxonomic family of saltwater clams, marine bivalve molluscs in the order Pectinida. As members of the superfamily Pectinoidea, they are closely related to scallops. Extant species are small in size, poorly known, and inhabit deep waters. None of the species within this family has a common name.

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.
Chlamys hastata, the spear scallop, spiny scallop or swimming scallop, is a species of bivalve mollusc in the family Pectinidae found on the west coast of North America from the Gulf of Alaska to San Diego, California.

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.
