For each species, the diet and feeding habits were characterized by depth strata using quantitative indices such as diet overlap, diet breadth and prey diversity. Diet variation with size and depth were also tested for the most abundant species. For shelf-living species, natantian and reptantian crustaceans together with teleosts were the most important preys. On slope bottoms, euphausiids were the preferential prey for <i>S. canicula</i> and <i>G. melastomus</i>, while <i>E. spinax</i> fed mainly on cephalopods. The most specialist and generalist diet corresponded to <i>G. melastomus</i> living on the upper slope and <i>S. canicul</i>a from the continental shelf, respectively. High overlap was found between all the skates on the continental shelf and the sympatric sharks <i>S. canicula</i> and <i>G. melastomus</i> on the slope. Significant overlap was also found between <i>S. canicula</i> and <i>R. clavata</i> on the continental shelf. Size was found to significantly affect the diet of <i>S. canicula, G. melastomus</i> and <i>R. clavata</i>, whereas depth affected exclusively <i>S. canicula</i>.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Feeding ecology of demersal elasmobranchs from the shelf and slope off the Balearic Sea (western Mediterranean)","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-05-21 01:32:55.189280","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Elasmobranch; batoid; shark; feeding habits; diet overlap; niche breadth; Mediterranean","OtherDescriptors":null,"Notes":null,"AnaPub":2011,"MonPub":null,"DateUpdate":"2018-02-13","DateCreate":"2017-07-17","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000299491700002","VABBcode":null,"OpenAcc":1,"DOI":"10.3989/scimar.2011.75n4633"},"refs":null,"anarec":{"AnaID":286702,"PubliDate":2011,"Pagination":"633-639","XtraPublOfAnaID":null,"ISBN":null,"Volume":"75","Issue":"4","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43791,"SerRR":"Scientia Marina (Barcelona).
