''Anomia'' is a genus of saltwater clams, marine bivalve mollusks in the family Anomiidae. They are commonly known as jingle shells because when a handful of them are shaken they make a jingling sound,〔Gofas, S. (2010) ''Anomia'' Linnaeus, 1758. In: Bouchet, P.; Gofas, S.; Rosenberg, G. (2010) World Marine Mollusca database. Accessed through: World Register of Marine Species at http://www.marinespecies.eu/aphia.php?p=taxdetails&id=137650 on 2010-06-06〕 though some are also known as saddle oysters.〔(【引用サイトリンク】title= Saddle oyster - Anomia ephippium )〕 This genus first appeared in the Permian period of China, Italy, and Pakistan.〔(Paleobiology database entry on Anomia )〕 ''Anomia'' species are common in both tropical and temperate oceans and live primarily attached to rock or other shells via a calcified byssus that extends through the lower valve.〔Ludvigsen, Rolf & Beard, Graham. 1997. West Coast Fossils: A Guide to the Ancient Life of Vancouver Island. pg. 109〕 ''Anomia'' shells tend to take on the surface shape of what they are attached to; thus if an ''Anomia'' is attached to a scallop shell, the shell of the ''Anomia'' will also show ribbing. 〔 == Reassigned species == As ''Anomia'' was erected very early in paleontology, several species have been reassigned; most of them are now recognized as brachiopods. * ''A. angulata'' = ''Yanishewskiella angulata'', brachiopod * ''A. biloba'' = ''Dicoelosia biloba'', brachiopod * ''A. bilocularis'' = ''Conchidium biloculare'', brachiopod * ''A. caputserpentis'' Linné, 1758 = undetermined terebratulid brachiopod * ''A. caputserpentis'' Linné, 1767 = ''Terebratulina caputserpentis'', brachiopod * ''A. craniolaris'' = ''Crania craniolaris'', brachiopod * ''A. crispa'' = ''Delthyris elegans'', brachiopod * ''A. detruncata'' = ''Megathyris detruncata'', brachiopod * ''A. furcata'' = ''Monia zelandica'' * ''A. nobilis'' = ''Monia nobilis'' * ''A. pectinata'' = ''Rhynchora pectinata'', brachiopod * ''A. placenta '' = ''Placuna placenta'' * ''A. psittacea'' = ''Hemithiris psittacea'', brachiopod * ''A. reticularis'' = ''Atrypa reticularis'', brachiopod * ''A. retusa'' Linné, 1758 = ''Terebratulina caputserpentis'', brachiopod * ''A. rubra'' = ''Kraussia rubra'', brachiopod * ''A. sella'' = ''Placuna quadrangula * ''A. squamula'' = ''Heteranomia squamula'' * ''A. terebratula'' = ''Terebratula terebratula'', brachiopod * ''A. vitrea '' = ''Gryphus vitreus'', brachiopod 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Anomia (genus)」の詳細全文を読む スポンサード リンク
