The Pteriomorphia comprise a subclass of saltwater clams, marine bivalve mollusks.[1] It contains several major orders, including the Arcoida, Ostreoida, Pectinoida, Limoida, Mytiloida, and Pterioida. It also contains some extinct and probably basal families, such as the Evyanidae, Colpomyidae, Bakevelliidae, Cassianellidae, and Lithiotidae.
This subclass of mollusks has lamellibranch gills, and is epibenthic. Some attach to the substrate using a byssus. The foot is reduced. The mantle margins are not fused. Gills are usually large and assist in feeding. This group includes the well known mussels, scallops, pen shells, and oysters.[2] It also includes the only members of the class bivalvia to have rudimentary eyes.
2010 Taxonomy
In 2010 a new proposed classification system for the Bivalvia was published by Bieler, Carter & Coan revising the classification of the Bivalvia, including the subclass Pteriomorphia.[3] However, the following taxonomy represents the current accepted arrangement of this subclass according to the World Register of Marine Species[4]
