In terms of the index of relative importance, the most important prey were amphipods (39.17%), polychaetes (22.33%) and lancelets (20.33%), followed by decapods (8.93%), cumaceans (5.41%) and isopods (3.41%). <i>Z. brevirostris</i> consumed mainly polychaetes and amphipods in spring and summer, more cumaceans in winter, consumed more lancelets in spring, and preyed more heavily on decapods and isopods in summer. As <i>Z. brevirostris</i> increased in size, the consumption of decapods, polychaetes and isopods was higher, but the consumption of amphipods decreased. Mature individuals of <i>Z. brevirostris</i> consumed more lancelets than juveniles. <i>Z. brevirostris</i> selected sand over other bottom types. The diet of <i>Z. brevirostris</i> can be influenced by the selectivity of this species for sandy bottoms. As sandy bottoms are exposed to a high intensity of bottom trawling, the positive selection of sandy bottoms increases the vulnerability of <i>Z. brevirostris</i> by exposing it to fishing mortality.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Feeding habits and habitat selectivity of the shortnose guitarfish, <i>Zapteryx brevirostris</i> (Chondrichthyes, Rhinobatidae), off north Argentina and Uruguay","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-10 01:31:41.411590","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Habitat selectivity; ontogenetic diet shift; Rhinobatidae; SouthwestAtlantic; trophic ecology","OtherDescriptors":null,"Notes":null,"AnaPub":2011,"MonPub":null,"DateUpdate":"2018-02-15","DateCreate":"2011-05-30","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000289616900003","VABBcode":null,"OpenAcc":0,"DOI":"10.1080/17451000.2010.515229"},"refs":null,"anarec":{"AnaID":205585,"PubliDate":2011,"Pagination":"365-377","XtraPublOfAnaID":null,"ISBN":null,"Volume":"7","Issue":"4","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":72882,"SerRR":"Marine Biology Research.
