Whelks use their shell lip to chip open the shell of their prey, often resulting in breakage to their own shells, as well as to their prey. <i>Mercenaria</i> evolved a larger shell in response to an intensifying level of whelk predation. Reciprocally, an increase in attack success (ratio of successful to unsuccessful attacks) and degree of stereotypy of attack position by the predator suggest reciprocal adaptation by <i>Sinistrofulgur</i> to increase efficiency in exploiting hard-shelled prey. A decrease in prey effectiveness (ratio of unsuccessful to total whelk predation attempts) and an increase in the minimum boundary of a size refuge from whelk predation for <i>Mercenaria</i> may indicate that predator adaptation has outpaced prey antipredatory adaptation. Evolutionary size increase in <i>Sinistrofulgur</i> most likely occurred in response to prey adaptation to decrease the likelihood of feeding-induced shell breakage and unsuccessful predation when encounters with damage-inducing prey occur, coupled with (or reinforced by) an evolutionary response to the whelk's own predators. Predator adaptation to <i>Mercenaria</i> best explains temporal changes in whelk behaviour to decrease performance loss (shell breakage) associated with feeding on hard-shelled prey; this behavioural change limits attacks on prey to when the whelk's shell lip is thickest and most resistant to breakage. Despite evidence of reciprocal adaptation between predator and prey, the contribution of <i>Mercenaria</i> to <i>Sinistrofulgur</i> evolution is likely only a component of the predator's response to dangerous bivalve prey. This study highlights the importance of understanding the interactions among several species in order to provide the appropriate context to test evolutionary hypotheses about any specific pair of species","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Coevolution of a marine gastropod predator and its dangerous bivalve prey","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2025-07-02 08:33:14.980000","timezone_type":1,"timezone":"+00:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":"arms race; busyconine; shell repair; escalation","Notes":null,"AnaPub":2003,"MonPub":null,"DateUpdate":"2019-08-30","DateCreate":"2003-11-17","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000186614800004","VABBcode":null,"OpenAcc":0},"refs":null,"anarec":{"AnaID":41785,"PubliDate":2003,"Pagination":"409-436","XtraPublOfAnaID":null,"ISBN":null,"Volume":"80","Issue":"3","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42441,"SerRR":"Biological Journal of the Linnean Society.
