This study compares the abilities of <i>C. Maenas</i> and those of an indigenous rocky-shore crab, </i>Plagusia chabrus</i>, to resist hydrodynamic forces. </i>C. Maenas</i> had less than half the vertical tenacity of <i>P. Chabrus</i> (371.5g and 780.5g respectively) and was unable to grip against as fast a unidirectional flow (0.23m s<sup>-1</sup> vs 0.53m s<sup>-1</sup>) as <i>P. chabrus. C. Maenas</i> also has significantly shorter and lighter limbs than <i>P. Chabrus</i> and the dactyls of its walking legs are poorly adapted to grip onto rocky substrata. We conclude that <i>C. Maenas</i> is poorly adapted to survive in wave-swept conditions and hence unlikely to displace indigenous crab species along the open wave-exposed coastline of South Africa. However, it may invade other sheltered locations, particularly Saldanha Bay and False Bay.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Why <i>Carcinus maenas</i> cannot get a grip on South Africa's wave-exposed coastline","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-05-22 01:31:13.421919","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2007,"MonPub":null,"DateUpdate":"2009-07-24","DateCreate":"2009-07-24","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000247419800011","VABBcode":null,"OpenAcc":0,"DOI":"10.2989/AJMS.2007.29.1.11.76"},"refs":null,"anarec":{"AnaID":139884,"PubliDate":2007,"Pagination":"123-126","XtraPublOfAnaID":null,"ISBN":null,"Volume":"29","Issue":"1","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":78939,"SerRR":"African Journal of Marine Science.
