On the muddy fine sand at \"la Noire\" station, the species forms a population with a mean density of 3.8 individuals per m super(2), with a range extending from 0 to 9.5 m super(-2), Laboratory experiments indicate that the majority of the population lives within the first centimetre-upper layer of the sediment. Eggs deposition occurs from January to May and veligers escape from the capsule after about three weeks, spending a part of this period of time in a free state within the capsule. The juveniles appear to grow at a rate of 0.28 mm per month during the autumn and the winter. Feces analysis indicates that <i>Mangelia nebula</i> feeds almost exclusively on a tubicolous polychaete, <i>Spio decoratus</i>. The examination of empty shells of <i>Mangelia nebula</i> reveals that his principal predator is a naticid gastropod.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Contribution à l'étude de la biologie des Turridae des côtes européennes: <i>Mangelia nebula</i> (Montagu)","OrigTitleLangCode":"fr","OrigTitleLangCodeExtended":"fre","OrigTitleLangID":22,"DateLastModified":{"date":"2025-07-02 08:58:19.190595","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":1989,"MonPub":null,"DateUpdate":"2016-03-04","DateCreate":"2004-08-17","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":1},"refs":null,"anarec":{"AnaID":65090,"PubliDate":1989,"Pagination":"347-359","XtraPublOfAnaID":null,"ISBN":null,"Volume":"30","Issue":"3","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42348,"SerRR":"Cahiers de Biologie Marine.
