Juvenile O. resiliens recruit to turf after a planktonic larval stage while <i>A. constricta</i> recruit through release from brooding adults. Skeletal development in <i>O. resiliens</i> and <i>A. constricta</i> is typical of most ophiuroids with diagnostic adult characters taking some time to appear. The main characters that can be used to distinguish the two species from an early stage are the number and arrangement of the oral papillae and the presence of disc spines. In <i>O. resiliens</i> diagnostic adult skeletal characters developed at 1.5 mm disc diameter. In <i>A. constricta</i> most identifying adult characters were evident at 700 µm disc diameter. Identification of juvenile <i>O. resiliens</i> is assisted by the presence of disc spines and thorny arm spines, features that disappear as the juveniles grow. Juvenile <i>A. constricta</i> did not develop disc spines or thorns on the arm spines.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Skeletal characters for identification of juvenile <i>Ophiactis resiliens</i> and <i>Amphiura constricta</i> (Echinodermata): cryptic ophiuroids in coralline turf habitat","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-14 01:31:15.156803","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2006,"MonPub":null,"DateUpdate":"2020-10-26","DateCreate":"2007-11-23","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000241311000032","VABBcode":null,"OpenAcc":0,"DOI":"10.1017/S0025315406014196"},"refs":null,"anarec":{"AnaID":117143,"PubliDate":2006,"Pagination":"1199-1207","XtraPublOfAnaID":null,"ISBN":null,"Volume":"86","Issue":"5","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43277,"SerRR":"Journal of the Marine Biological Association of the United Kingdom.
