Pterioidea
Pterioidea is a superfamily of epifaunal marine bivalves mostly inhabiting continental shelf regions of tropical and subtropical oceans. The superfamily includes the economically-important saltwater pearl oysters as well as the oddly shaped hammer oysters (neither of which, however, is considered a true oyster). A number of species have found use as model organisms in the fields of medicine and science. It includes the following three accepted living families: * Malleidae, the hammer oysters, Lamarck, 1818 *Pteriidae Pteriidae, also called the feather oysters, is a family of medium-sized to large saltwater clams. They are pearl oysters, marine bivalve molluscs in the order Pteriida. Some of the species in this family are important economically as the sou ..., the pearl oysters, tree oysters, and winged oysters, Gray, 1847 (1820) * Pulvinitidae, a family of rare deep sea oysters, no common name, Stephenson, 1941 Fossil families include: *Family † Aviculopectinidae *F ...

Bivalve
Bivalvia (), in previous centuries referred to as the Lamellibranchiata and Pelecypoda, is a class (biology), class of marine and freshwater Mollusca, molluscs that have laterally compressed bodies enclosed by a shell consisting of two hinged parts. As a group, bivalves have no head and they lack some usual molluscan organs, like the radula and the odontophore. They include the clams, oysters, Cockle (bivalve), cockles, mussels, scallops, and numerous other family (biology), families that live in saltwater, as well as a number of families that live in freshwater. The majority are filter feeders. The gills have evolved into Ctenidium (mollusc), ctenidia, specialised organs for feeding and breathing. Most bivalves bury themselves in sediment, where they are relatively safe from predation. Others lie on the sea floor or attach themselves to rocks or other hard surfaces. Some bivalves, such as the scallops and file shells, can nekton, swim. The shipworms bore into wood, clay, or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pteriida
The Pteriida are an order of large and medium-sized marine bivalve mollusks. It includes five families, among them the Pteriidae (pearl oysters and winged oysters). 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 suborder Pteriida. *Superfamily Ambonychioidea **Family †Alatoconchidae **Family † Ambonychiidae **Family † Lunulacardiidae **Family † Monopteriidae **Family † Myalinidae **Family † Mysidiellidae **Family † Ramonalinidae *Superfamily Pinnoidea **Family Pinnidae *Superfamily † Posidonioidea Neumayr, 1891 **Family † Posidoniidae Neumayr, 1891 (Devonian to Cretaceous) **Family † Aulacomyellidae Ichikawa, 1958 **Family † Daonellidae Neumayr, 1891 **Family † Halobiidae Kittl, 1912 (Devonian to Triassic) *Superfamily Pterioidea **Family †Bakevelliidae (Triassic to Eocene) **Family †Cassianellidae (Middle to Late Tria ...

Malleidae
Malleidae, or hammer oysters, is a family of saltwater clams. They are related to the pearl oysters, in the order PteriidaGofas, S. (2011). Malleidae. Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=23067 on 2012-01-02 and the superfamily Pterioidea. The shells of most of these animals are T-shaped, with the hinge along the top of the T, and with the byssus emerging from the hinge. An oblique ligament holds the hinge. The shell is partially nacreous. There is a single, large adductor muscle. The exhalant current exits at the hinge. Most hammer oysters live in tropical, coralline areas. Genera * ''Malleus The malleus, or hammer, is a hammer-shaped small bone or ossicle of the middle ear. It connects with the incus, and is attached to the inner surface of the eardrum.

Taxonomic Rank
In biological classification, taxonomic rank is the relative level of a group of organisms (a taxon) in an ancestral or hereditary hierarchy. A common system consists of species, genus, family, order, class, phylum, kingdom, domain. While older approaches to taxonomic classification were phenomenological, forming groups on the basis of similarities in appearance, organic structure and behaviour, methods based on genetic analysis have opened the road to cladistics. A given rank subsumes under it less general categories, that is, more specific descriptions of life forms. Above it, each rank is classified within more general categories of organisms and groups of organisms related to each other through inheritance of traits or features from common ancestors. The rank of any ''species'' and the description of its ''genus'' is ''basic''; which means that to identify a particular organism, it is usually not necessary to specify ranks other than these first two.

Cassianellidae
Cassianellidae is a small extinct family of prehistoric bivalves which lived from the Middle Triassic, Ladinian stage through the Late Triassic Norian stage.The Paleobiology Database Cassianellidae entry accessed 2 January 2012 It has been suggested that the family may have evolved from the related family Bakevelliidae. Bakevelliidae species are found in North America, South America, Europe, the Middle East, and Asia. Living a stationary life attached to substrate in marine and brackish environments, they formed shells of an |
