Bivalvia is a descriptor in the National Library of Medicine's controlled vocabulary thesaurus, MeSH (Medical Subject Headings).Descriptors are arranged in a hierarchical structure, which enables searching at various levels of specificity A bivalve is an animal belonging to the class Bivalvia. Its name is a reference to the two shells, called valves , that protect its soft inner body parts. The valve is opened and closed using a.

The bivalves are a large class of molluscs, also known as pelecypods.. They have a hard calcareous shell made of two parts or 'valves'. The soft parts are inside the shell. The shell is usually bilaterally symmetrical.. There are over 30,000 species of bivalves, including the fossil species. There are about 9,200 living species in 1,260 genera and 106 families With approximately 15,000 described recent species, Bivalvia is the second largest molluscan class-level taxon. Compared to other conchiferan molluscs, the bivalve body plan has undergone several reductions, such as the lack of a distinct head including radula and buccal muscles, which is also reflected in the relatively simple nervous system exhibited by most bivalves

What are synonyms for class Bivalvia Life history & ecology In most bivalves, the pallial cavity contains a pair of very large gills that are used to capture food particles suspended in the inhalant water current. The food is bound in mucus that is carried by cilia along food grooves on the edges of the gills to the mouth region. Here particles are sorted on the ciliated labial palps before they enter the mouth. The food then moves to the stomach, which is large and complex with sophisticated ciliary sorting mechanisms, and usually, a rotating hyaline rod which liberates enzymes into the stomach. Digestion is carried out in the large paired digestive diverticula (the stomach).

  2. Bivalve - Bivalve - Classification: No system of classification erected for the Bivalvia has been accepted by all. Paleontologists interpret bivalves on the basis of shell features, notably shell and ligament structure, arrangement of hinge teeth, and body form as interpreted from internal muscle scars. Investigators of Holocene (11,700 years ago to the present) forms use other anatomic.
  3. The evolutionary relationships of bivalve lineages are not currently well understood. There appear to be many parallel lines of evolution that obscure relationships between taxa. However, there is some consensus that Protobranchia (Palaeotaxodonta), Pteriomorpha, Heterodonata, and Anomalodesmata are legitimate taxonomic groups. Pteriomorphans, characterized by reduced or absent siphons, usually have filibranch ctenida. Heterodontans are typified by possessing large siphons and have lamellibranch gill structure. Lastly, anomalodesmatans are the septibranch bivalves.
  4. Bivalvia (/ ˈ b aɪ v æ l v i ə /), in previous centuries referred to as the Lamellibranchiata and Pelecypoda, is a class of marine and freshwater molluscs that have laterally compressed bodies enclosed by a shell consisting of two hinged parts. Bivalves as a group have no head and they lack some usual molluscan organs like the radula and the odontophore.They include the clams, oysters.
  5. Anomalodesmata This rather diverse group includes the watering pot shells (Clavagellidae) and about a dozen other small families, some of which are found only in rather deep water. A few taxa are cemented to the substrate, but most are shallow burrowers and all are marine. One group of mostly deep-water families (collectively known as septibranchs) have the gills modified as pumping septa and feed on small crustaceans. The shells of some anomalodesmatans are nacreous and most have a simple hinge.

  6. Bivalves are easily recognized by their two-halved shell. They can burrow into the sediment or live on the ocean floor. Some can even move around through the water by snapping their shell open and shut to swim. Not all bivalves still have a shell though; some have evolved a reduced shell or have completely lost the shell.

Bivalves have no head, and they also lack a radula. They include clams, oysters, cockles, mussels, scallops, and numerous other families that live in saltwater, as well as a number of families that live in freshwater. The majority are filter feeders. Most bivalves are filter feeders, but some are scavengers or even predators. The four main feeding types of bivalves are defined by gill structure. In protobranchs, the ctenida are used only for respiration and food is caught by the labial palps. In filibranchs and lamellibranchs, the ctenida trap the food particles in their mucous coating and transfer the food to the labial palps via ciliary action. These two groups differ in that the branches of the ctenida are connected only by ciliary junctions in filibranchs whereas lamellibranchs have tissue connecting the branches of the ctenida. A septibranch bivalve has a septum across its mantle cavity, which functions to pump in food. Thus, Bivalvia is the only molluscan class characterized by the absence of a radula.

Brachiopods and bivalves have likely been competitors since they first arose in the Cambrian. That said, brachiopods were much more diverse than bivalves throughout the Paleozoic, right up until the end-Permian mass extinction Many bivalves (such as clams or oysters) are used as food in places all over the world. Pearl oysters are used for commercial production of pearls. Bivalves can also cause economic damage. The glochidia larvae of some freshwater mussels can be serious parasites of fish, and some marine bivalves bore through wood, causing damage to wooden ships, pilings, and other wood structures.

Bivalves are hermaphroditic or have separate sexes. The eggs are typically small and not very yolk-rich. Fertilization is usually external, but in brooding species occurs in the mantle pallial cavity. For external fertilizers where the eggs and sperm are released into the water, the embryos often develop in the water column and go through both trochophore and veliger larval stages. Although morphologically similar to the gastropod veliger stage, phylogenetic analyses suggest that these larval stages are convergent and not homologous. Many other bivalves retain their eggs in the pallial cavity and suck in sperm with the inhalant water current. In some brooding bivalves the larvae develop in special pouches in the gills, or simply lie in the pallial cavity in others. Many brooding bivalves release their young as swimming veliger larvae while others retain them longer and release them as juveniles. Freshwater mussels (Unionoidea) have glochidial larvae that attach to fish as ectoparasites.

In most bivalves the two halves of the mantle are fused around the edges, with openings anteriorly for the foot and posteriorly for the exhalant opening through which the water is expelled from the pallial cavity. This exhalant also carries waste products and gametes. The inhalant opening, through which water is carried into the pallial cavity, is also posteriorly located in most bivalves, lying just below the exhalant opening. The mantle edge is also where contact is made with the external world and is, consequently where any sense organs are located. These are usually simple sensory cells but in some there are pallial eyes and/or sensory tentacles.

Introduction. Through their water filtration action, freshwater mussels (Bivalvia: Unionida) serve important roles as aquatic ecosystem engineers (Gutiérrez et al. 2003; Spooner and Vaughn 2006), and can greatly influence species composition (Aldridge et al. 2007).From a biological standpoint, they are also well known for producing obligate parasitic larvae that metamorphose on freshwater.

Bivalvia (Pelecypoda, Lamellibranchia; phylum Mollusca) A class of molluscs in which the body is laterally compressed, there is no definite head, and the soft parts are enclosed between two oval or elongated, calcareous valves.The valves are not equilateral, being united on the dorsal side by a toothed hinge. Most are bilaterally symmetrical along the plane of junction of the two valves Characteristics: The obvious commonality among all bivalves is that they have two shells joined together by strong ligaments. The side with the ligaments are called the dorsal margin in contrast to the ventral margin Bivalves. The mollusks that have a hinged, two-part shell joined by strong muscles are called bivalves.

It is thought that they are close relatives of modern bivalves. The larval shell was a single valve that transformed into a non-hinged, gaping bivalve shell as it grew. They probably evolved from helcionelloidean monoplacophorans in the Early Cambrian, underwent an extensive Late Cambrian and Early Ordovician radiation and survived until the Permian. Rostroconchs are thought to share common ancestry with the Bivalvia (Pojeta and Runnegar 1976; Waller 1998).
