The ooplasm contains lipid droplets, electron-dense globules, phagosomes and rod-like inclusions. The most interesting feature of the oocytes is the high number of bacteria which are present in phagocytotic vacuoles in the oocyte cytoplasm and which derive from the mesohyl. While in other sponges the vacuoles usually contain a single bacterium, in <i>T. aurantium</i> the vacuoles are large and contain groups of bacteria. The bacteria engulfed by the oocytes of <i>T. aurantium</i> may perform a trophic role but their presence may also be interpreted as a means of transfer to the embryos. The lack of nurse cells around the oocytes suggests that yolk production in <i>T. aurantium</i> occurs by active uptake of nutrients from the mesohyl.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Ultrastructural study of the mature oocyte of <i>Tethya aurantium</i> (Porifera: Desmospongiae)","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":2002,"MonPub":null,"DateUpdate":"2016-04-22","DateCreate":"2002-09-25","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":1},"refs":null,"anarec":{"AnaID":27610,"PubliDate":2002,"Pagination":"1-7","XtraPublOfAnaID":null,"ISBN":null,"Volume":"43","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42348,"SerRR":"Cahiers de Biologie Marine.
