Pteriida
The Pteriida are an order (biology), order of large and medium-sized Marine (ocean), marine bivalve mollusc, 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 †Inoceramidae **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 Eoc ...

Pteriidae
Pteriidae, also called the feather oysters, is a family (biology), family of medium-sized to large saltwater oysters. They are pearl oysters, Marine (ocean), marine bivalve mollusks in the order Pteriida. Some of the species in this family are important economically as the source of saltwater pearls. Genera Genera in the family Pteriidae include: * ''Crenatula'' Lamarck, 1803 * ''Electroma (bivalve), Electroma'' Stoliczka, 1871 * ''Pinctada'' Röding, 1798 * ''Pteria (bivalve), Pteria'' Scopoli, 1777 - winged oysters * ''Vulsella (bivalve), Vulsella'' Röding, 1798 References * Arthur William Baden Powell, Powell A.

Bivalve
Bivalvia () or bivalves, in previous centuries referred to as the Lamellibranchiata and Pelecypoda, is a class (biology), class of aquatic animal, aquatic molluscs (marine and freshwater) that have laterally compressed soft bodies enclosed by a calcified exoskeleton consisting of a hinged pair of half-bivalve shell, shells known as valve (mollusc), 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 ctenidium (mollusc), ctenidia, specialised organs for feeding and breathing. Common bivalves include 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. Majority of the class are benthic filter feeders that bury themselves in sediment, where they are relatively safe from predation. Others lie on the sea floor or attach themselves to rocks or other h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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, 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 *Family †Bakevelliidae Bakevelliidae is an extinct family (biology), family of prehistoric bivalves that lived from the Late Mississippian age, Mississippian until the Middle Eocene.

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. There are about 22 species in this family. 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. The word is Latin for 'hammer' or 'mallet'. It transmits the sound vibra ...'' Lamarck, 1799 * '' N ...

Pinnidae
The pinnidae are a taxonomic family of large saltwater clams sometimes known as pen shells. They are marine bivalve molluscs in the order Pteriida. Shell description The shells of bivalves in this family are fragile and have a long and triangular shape, and in life the pointed end is anchored in sediment using a byssus. The shells have a thin but highly iridescent inner layer of nacre in the part of the shell near the umbos (the pointed end). The family Pinnidae includes the fan shell, '' Atrina fragilis'', and '' Pinna nobilis'', the source of sea silk. Some species are also fished for their food value. Human use As Joseph RosewaterRosewater, Joseph. (1961). “The Family Pinnidae in the Indo-Pacific.” ''Indo-Pacific Mollusca'', vol. 1, no. 4. September 28, 1961, pp. 175-176. commented in 1961: "“The Pinnidae have considerable economic importance in many parts of the world. They produce pearls of moderate value.

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 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 |
Plicatostylidae Anatomy
Plicatostylidae is a family of extinct large-sized epifaunal marine to brackish bivalves that inhabited Europe, Asia, Africa and America during the Jurassic, though they survived until the Eocene. These groups are informally known as "Lithiotids" or "Lithiotid Bivalves". They represent large reef builders, analogues to the younger Rudists and modern '' Crassostrea'', ''Magallana'' and less extent to ''Tridacna''. Ecology Plicatostylid bivalves were large sized, with the spoon-shaped '' Lithiotis'' reaching heights of 25-30 cm and a thickness of up to 1.5-3 cm, with the largest as high as 50 cm and some specimens of '' Lithioperna'' reaching 70 cm and 4 cm thick. They developed in large reef systems like modern '' Crassostrea'', but in warm, shallow seas, with some bioherms attaining lengths over 60 m and thicknesses of 3-5 m. They were rapid growers, with their shells often made of aragonite, leading to massive shell accumulations that shaped the sea floor, known as the "Lit ...

Alatoconchidae
Alatoconchidae is an extinct family of prehistoric bivalves that lived in the early to middle Permian period. Genera belonging to Alatoconchidae are characterized by their shell that is strongly compressed in the dorsoventral direction. Some species reached large sizes of as much as long. It is hypothesized that some species in this family got energy from chemosynthetic bacteria. Occurrence Fossil records of Alatoconchidae are known from the early to middle Permian. They are found in shallow marine carbonates across widely separated areas, such as Croatia, Tunisia, Oman, Afghanistan, Iran, Thailand, Malaysia, Philippines, Japan, Alaska and South China. History In 1968, ''Shikamaia akasakaensis'' from Japan, named after palaeontologist Shikama Tokio, is described, but due to its unique shape and fragmentary fossil preservation, it was originally classified as Animalia ''incertae sedis''. The Alatoconchidae family was created in 1973, and included genus '' Alatoconcha''. M ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Description The bivalve shell is usually long, but can reach . Its shape differs depending on the region it inhabits. Like all pen shells, it is relatively fragile to pollution and shell damage. It attaches itself to rocks using a strong byssus composed of many silk-like threads which used to be made into cloth. The animal secretes these fibres from its byssus gland; ...
