The first stomach contained two coils of hemp rope, the second stomach contained beaks of cephalopods, nearly all of which were collected and examined. Of these, 2,010 were lower beaks; 2,000 were identified as <i>Gonatus fabricii</i> (Lichtenstein, 1818), seven as <i>Teuthowenia megalops</i> (Prosch, 1849) and three as the octopod <i>Alloposus mollis</i> Verrill, 1880 (= <i>Haliphron atlanticus</i> Steenstrup, 1859). The predominance of <i>Gonatus</i> and lack of many North Atlantic species strongly suggests that the whale had last fed in the Norwegian Sea at least three days before stranding, and had migrated over about 600 miles due South, instead of by the usual path to the West of the British Isles. Comparisons are made of the size of the beaks with those collected from sperm whales caught off Iceland and from two bottlenosed whales stranded on the coasts of the Faroes and Denmark.","AbstractOtherLang":"Op 3 november 1994 strandde een sub-adult potvismannetje met een lengte van 14,8 m in de zuidelijke Noordzee tussen de eilanden Terschelling en Ameland. De eerste maag bevatte twee trossen van henneptouw, de tweede maag bevatte inktvissnavels, die bijna allemaal verzameld en onderzocht werden. 2.010 van deze waren ondersnavels; 2.000 waren afkomstig van <i>Gonatus fabricii</i> (LICHTENSTEIN, 1918), zeven van <i>Teuthowenia megalops</i> (PROSCH, 1849) en drie van de octopode <i>Alloposus mollis</i> VERRIL, 1880 (= <i>Haliphron atlanticus</i> STEENSTRUP, 1859). Het overwicht aan <i>Gonatus</i> en het gebrek aan vele Noord-Atlantische soorten doet sterk vermoeden dat de walvis zich voor het laatst had gevoed in de Noorse Zee, tenminste drie dagen vóór de stranding, en ongeveer 600 mijl gemigreerd was in zuidelijke richting, in plaats van de normale weg langs het westen van de Britse Eilanden te nemen. De afmetingen van de inktvissnavels worden vergeleken met de snavels verzameld uit de magen van potvissen gevangen in de buurt van Ijsland en van twee butskoppen gestrand op de kusten van de Faroër eilanden en Denemarken.","BibLvlCode":"AS","StandardTitle":"Cephalopods in the stomach of a sperm whale stranded between the islands of Terschelling and Ameland, southern North Sea","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":"sperm whale, stranding, cephalopods, squids, octopods, feeding, migration","Notes":null,"AnaPub":1997,"MonPub":null,"DateUpdate":"2021-02-23","DateCreate":"2000-08-24","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":0},"refs":null,"anarec":{"AnaID":825,"PubliDate":1997,"Pagination":"53-55","XtraPublOfAnaID":null,"ISBN":null,"Volume":"67","Issue":"suppl.","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":44202,"SerRR":"Bulletin van het Koninklijk Belgisch Instituut voor Natuurwetenschappen.
