Red algae are epiphytic on upper colony surfaces, and epizoic forms include tube-worms, sponges, mollusca and a ctenostome bryozoan, <i>Sundanella</i> sp. Minute tube dwelling isopods act as cleaning symbionts. Zooids of the outer zones of mature colonies are polymorphic and sexual in function. Subperipheral zones of zooids with concave, raised distal walls have ovaries and are inferred to be female, brooding zooids. Peripheral zones of zooids with well-developed muscle systems and modified lopophores (consisting of long, paired, unciliated tentacles and greatly elongated tentacle sheaths) contain sperm in their visceral coeloms. They are inferred from morphology and behaviour to be male zooids. The occurrence of similar zones of polymorphic zooids in other species of <i>Selenairia</i>, and their significance in study of fossil populations is briefly discussed. Colonies respond to blue green visible light and move towards it, but are apparently unaffected by red light or by ultra-violet and infrared radiation.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Observations of living colonies of <i>Selenaria</i> (Bryozoa, Cheilostomata) 2","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2024-12-10 01:33:17.368041","timezone_type":1,"timezone":"+01:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":1981,"MonPub":null,"DateUpdate":"2016-02-29","DateCreate":"2004-06-10","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:A1981LZ91700008","VABBcode":null,"OpenAcc":1},"refs":null,"anarec":{"AnaID":62870,"PubliDate":1981,"Pagination":"207-219","XtraPublOfAnaID":null,"ISBN":null,"Volume":"22","Issue":"2","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42348,"SerRR":"Cahiers de Biologie Marine.
