Spawning begins slowly and reaches a maximum at the intervening neap tides and then declines in intensity.Both eggs and sperms are discharged from the burrows at extreme low water to lie on the surface of the sand. Here fertilization occurs.No germ cells were detected in the body cavity from November to June, but from August onwards to the end of October 98% of the adult worms are ripe.At the end of the spawning period about 40% of the adults die.A brief description of gametogenesis and of the mature gametes is given.Germ cells are discharged through the nephridia.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"A contribution to our knowledge of the life history of <i>Arenicola marina</i> L.","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-14 01:31:02.718191","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":"<i>Arenicola marina</i>","Notes":null,"AnaPub":1948,"MonPub":null,"DateUpdate":"2020-07-17","DateCreate":"2002-02-20","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":0,"DOI":"10.1017/S0025315400056022"},"refs":null,"anarec":{"AnaID":23016,"PubliDate":1948,"Pagination":"554-580","XtraPublOfAnaID":null,"ISBN":null,"Volume":"27","Issue":"3","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43277,"SerRR":"Journal of the Marine Biological Association of the United Kingdom.
