Bivalvia. Origem: Wikipédia, a enciclopédia livre. Em biologia, bivalvia (do latim bi, duplicado + valva, porta de duas folhas, valva) anteriormente Pelecypoda e Lamellibranchia, é a classe do filo Mollusca que inclui os animais aquáticos popularmente designados por bivalves. Estes organismos caracterizam-se pela presença de uma concha. Tweekleppigen (Bivalvia) zijn een klasse van in water levende weekdieren (Mollusca). Tweekleppigen hebben een zijdelings afgeplat lichaam dat omgeven wordt door een harde schelp, bestaande uit twee helften die vaak grofweg elkaars spiegelbeeld zijn.Beide kleppen hebben vaak in elkaar grijpende slottanden en worden bijeen gehouden door sluitspieren Although Bivalvia is a valid name for the class and has gained general acceptance following the Treatise on Invertebrate Palaeontology (Cox in Moore, 1969), some would prefer Pelecypoda, on the grounds that other animal groups exist with bivalved shells (e.g. Brachiopoda, Ostracoda and some Gastropoda), that some animals attributed to.

  1. Bivalves are molluscs, well-known to humans who have developed a taste for many of them. This group includes oysters, mussels, pipis, cockles, scallops and clams. The name bivalve means 'two valves'. The soft-bodied animals live inside the shell valves, which are joined together by a toothed hinge and a flexible ligament
  2. Abstract. The study of molluscan immune systems, in particular those of bivalve molluscs (e.g., clams, oysters, scallops, mussels), has experienced great growth in recent decades, mainly due to the needs of a rapidly growing aquaculture industry to manage the impacts of disease and the wider application of -omic tools to this diverse group of invertebrate organisms

The valves are the parts usually found as fossils, but decay of the elastic hinge tissue that joins them means that they are rarely preserved together.
