Other questions are more specific to bivalves, a group that radiated so successfully and nowadays predominantly specializes as infaunal and sessile epifaunal suspension feeders. This paper highlights and explores unanswered questions, from the seemingly trivial and mundane (<i>e.g</i>., how many species are actually out there?), to exploring enigmatic clades about which we know extremely little besides their shells, to macroevolutionary questions that could best be addressed by bivalve-based data. Fast-developing molecular approaches, including the first genome-level and transcriptomic data, a resurgence of detailed morphological and soft-anatomical research, and a renewed focus on Bivalvia by biological and paleontological workers provide us with an opportunity to address such issues. Coordination of efforts - and reciprocal illumination - across traditional disciplinary boundaries will be key factors in such endeavors.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Bivalvia - A discussion of known unknowns","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-06 01:33:36.376696","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"systematics, taxonomy, bivalves, phylogeny, technique","OtherDescriptors":null,"Notes":null,"AnaPub":2013,"MonPub":null,"DateUpdate":"2018-02-13","DateCreate":"2017-08-09","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000338769900015","VABBcode":null,"OpenAcc":0,"DOI":"10.4003/006.031.0105"},"refs":null,"anarec":{"AnaID":287754,"PubliDate":2013,"Pagination":"123-133","XtraPublOfAnaID":null,"ISBN":null,"Volume":"31","Issue":"1","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42081,"SerRR":"American Malacological Bulletin.
