In contrast, however, its form, functional morphology and lifestyle have received scant attention. This study describes the anatomy of <i>A. islandica</i> and provides information to match fossil and rRNA evidence that it is a living fossil probably associated with a Cretaceous heterodont mactrid group adapted to deposit feeding. <i>Arctica islandica</i> lives in buried motionless repose feeding on the carbon-rich seabed surface micro-layer of northern boreal continental shelves. This study concludes that the indolent lifestyle exhibited by <i>A. islandica</i>, along with tissue antioxidant levels sustained into gerontocy, predisposes it to negligible senescence. As a consequence, and as has been demonstrated elsewhere, <i>A. islandica</i> can live for centuries – the current longevity record being 405 years obtained through an analysis of shell growth rings. Its value, therefore, as a ‘tree of the sea’, or archival proxy for marine environmental change in the boreal North Atlantic, is not just an appropriate simile with terrestrial tree rings, but an example and reflection of a conservative morphology and simple lifestyle fostering longevity.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"The biology and functional morphology of <i>Arctica islandica</i> (Bivalvia: Arcticidae): A gerontophilic living fossil","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-10 01:31:41.692864","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Anatomy; Arctica; biology; living fossil; long-living","OtherDescriptors":null,"Notes":null,"AnaPub":2011,"MonPub":null,"DateUpdate":"2018-02-15","DateCreate":"2011-09-12","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000299033300002","VABBcode":null,"OpenAcc":0,"DOI":"10.1080/17451000.2010.535833"},"refs":null,"anarec":{"AnaID":207685,"PubliDate":2011,"Pagination":"540-553","XtraPublOfAnaID":null,"ISBN":null,"Volume":"7","Issue":"6","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":72882,"SerRR":"Marine Biology Research.
