Tests with 46 worms showed that they fed suctorially on <i>Ampelisca vadorum, Ampithoe longimana, Corophium acherusicum</i> and <i>C. tuberculata</i>. Corophiids were preferred. Upon contact with an amphipod, the proboscis is everted and strikes the prey on the ventral side, immobilizing it in a few minutes. The worm probes the sternal region with its head and everts its proboscis one or more times during the process. The exoskeleton is eventually penetrated by the head, and the stomach is everted into the hemocoel as a flattened funnel-like structure. Peristaltic undulations of the body signify the suctorial action that removes the living contents from the exoskeleton. The actual feeding process (from head penetration to removal of the head) takes about 7 min. <i>O. dorsalis</i> is only the third species within the Prosorhochmidae for which the feeding behavior has been documented. The other two are terrestrial species, and are also suctorial.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Food and feeding behavior of the hoplonemertean <i>Oerstedia dorsalis</i>","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":null,"Notes":null,"AnaPub":1988,"MonPub":null,"DateUpdate":"2023-08-10","DateCreate":"2023-08-10","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:A1988L756200007","VABBcode":null,"OpenAcc":0,"DOI":"10.1007/bf00027977"},"refs":null,"anarec":{"AnaID":366029,"PubliDate":1988,"Pagination":"47-51","XtraPublOfAnaID":null,"ISBN":null,"Volume":"156","Issue":"1","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42943,"SerRR":"Hydrobiologia.
