All known extant myzostomids are associated with echinoderms and infest their integument, gonads, celom, or digestive system. Using nuclear (18S rDNA) and mitochondrial (16S and COI) DNA sequence data from 37 myzostomid species representing nine genera, we report here the first molecular phylogeny of the Myzostomida and investigate the evolution of their various symbiotic associations. Our analyses indicate that the two orders Proboscidea and Pharyngidea do not constitute natural groupings. Character reconstruction analyses strongly suggest that (1) the ancestor of all extant myzostomids was an ectocommensal that first infested crinoids, and then asteroids and ophiuroids, and (2) parasitism in myzostomids emerged multiple times independently.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Molecular phylogenetic analyses indicate multiple independent emergences of parasitism in Myzostomida (protostomia)","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-04-29 01:32:42.355123","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"character evolution; commensalism; crinoids; echinoderms; molecular phylogeny; myzostomids; symbiosis","OtherDescriptors":null,"Notes":null,"AnaPub":2006,"MonPub":null,"DateUpdate":"2021-06-01","DateCreate":"2021-05-17","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000236945800003","VABBcode":null,"OpenAcc":0,"Handle":"10.1080/10635150500481317"},"refs":null,"anarec":{"AnaID":338223,"PubliDate":2006,"Pagination":"208-227","XtraPublOfAnaID":null,"ISBN":null,"Volume":"55","Issue":"2","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43945,"SerRR":"Systematic Biology.
