Veneroida
Venerida (formerly Veneroida) is an order (biology), order of mostly saltwater but also some freshwater bivalve molluscs. This order includes many familiar groups such as many clams that are valued for food and a number of freshwater bivalves. Since the 2000s, the taxonomy currently represented in the World Register of Marine Species (WoRMS) classifies several taxa contained in the former Veneroida into other orders, such as the new Cardiida (for Cardioidea and Tellinoidea) and Carditida (cockles and their allies). Description Venerids are generally thick-valved, equal-valved and isomyarian (that is, their Adductor muscles (bivalve), adductor muscles are of equal size). Three main hinge teeth are characteristic of the subclass Heterodonta, to which this order belongs. Many species are active rather than sessile. However, they tend to be filter feeders, feeding through paired Siphon (mollusks), siphons, with a characteristic folded gill structure adapted to that way of life. In 2 ...

Freshwater Bivalves
Freshwater bivalves are one kind of freshwater mollusc, along with freshwater snails. They are bivalves that live in fresh water as opposed to salt water, which is the main habitat type for bivalves. The majority of species of bivalve molluscs live in the sea, but in addition, a number of different families live in fresh water (and in some cases, also in brackish water). These families belong to two different evolutionary lineages (freshwater mussels and freshwater clams), and the two groups are not closely related. Freshwater bivalves have a simple morphology that varies among taxa, and are distributed around most regions of the world. Species in the two groups vary greatly in size. Some pea clams (''Pisidium'' species) have an adult size of only 3 mm. In contrast, one of the largest species of freshwater bivalves is the swan mussel, in the family Unionidae; it can grow to a length of 20 cm, and usually lives in lakes or slow rivers. Freshwater pearl mussels are econo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gonzalo Giribet
Gonzalo Giribet is a Spanish-American invertebrate zoologist and Alexander Agassiz Professor of zoology working on systematics and biogeography at the Museum of Comparative Zoology in Harvard University. He is a past president of the International Society for Invertebrate Morphology, of the Willi Hennig Society, and vice-president of the Sociedad Española de Malacología (Spanish Malacological Society). Early life Giribet was born in Burgos and grew up in Vilanova i la Geltrú, Catalonia to a legal administrator and an engineer who worked in nuclear power plants. As a boy, he enjoyed windsurfing, beachcombing, and collecting sea shells. He attended, and then graduated from, the University of Barcelona in 1993, with bachelor's degrees in zoology and fundamental biology. He completed his doctorate in animal biology in 1997. He then moved to the American Museum of Natural History for postdoctoral research with Ward Wheeler, and from there moved to Harvard University in 2000, wh ...

Bivalve
Bivalvia (), 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. 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, 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. The gills have evolved into 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 swim. The shipworms bore into wood, clay, or stone and live inside these substances. The shell of a bivalve is composed of calc ...

Heterodonta
Heteroconchia is a taxonomic infraclass of saltwater clams, marine bivalve molluscs, belonging to the subclass Autobranchia This infraclass includes the edible clams, the cockles and the Venus clams. Description These bivalves are distinguished by having the two halves of the shell equally sized (i.e, they are ''equivalved'') and having a few cardinal teeth separated from a number of long lateral teeth. Their shells lack a nacreous layer, and the gills are lamellibranch in form. Most species have a siphon. Orders and families The following tree is their info which has been updated with the latest information from the World Register of Marine Species: Infraclass: Heteroconchia *Unclassified family: † Lipanellidae *Subterclass: Archiheterodonta **Order: † Actinodontida ***Superfamily: † Amnigenioidea ****Family: † Amnigeniidae ****Family: † Montanariidae ****Family: † Zadimerodiidae *** Superfamily: † Anodontopsoidea **** Family: † Actinodontidae **** Fami ...

Arcticidae
The Arcticidae are a family of marine clams in the order Venerida. The only living species in the family is ''Arctica islandica''. There are also many fossil species classified in a number of genera Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclat .... Fossilworks.

Invertebrate Biology
The American Microscopical Society (AMS) is a society of biologists dedicated to promoting the use of microscopy. A cohort of biologists and science educators, the AMS's members use a wide array of microscopical techniques (light microscopy, electron microscopy, fluorescence and confocal microscopes) to further their research and eventually publish their research in its journal Invertebrate Biology. Yearly meetings conducted by the AMS focus on innovation in current microscopy techniques. Workshops conducted by the AMS are focused not only on microscopy techniques themselves, but also on the organisms that current members are studying with these microscopy techniques. History Founded in 1878 as an outgrowth of the first National Microscopical Congress, the first members of the AMS were biologists, medical doctors, and dentists interested in incorporating light microscopy into their clinical work. During this time period, the compound microscope was a new technology and the AM ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
