Its peculiarity and highly unusual lifestyle as a meiobenthic clade living on sand grains has fascinated many biologists. In particular its systematic relationship to other bryozoans remains a mystery. Despite numerous searches for <i>M. ambulans</i> in its type locality Helgoland, a locality with a long-lasting marine station and tradition of numerous courses and workshops, it has never been reencountered until today. Here we report the first observations of this almost mythical species, <i>Monobryozoon ambulans</i>.<h3>Results</h3>For the first time since 1938, we present new modern, morphological analyses of this species as well as the first ever molecular data. Our detailed morphological analysis confirms most previous descriptions, but also ascertains the presence of special ambulatory polymorphic zooids. We consider these as bud anlagen that ultimately consecutively separate from the animal rendering it pseudo-colonial. The remaining morphological data show strong ties to alcyonidioidean ctenostome bryozoans. Our morphological data is in accordance with the phylogenomic analysis, which clusters it with species of <i>Alcyonidium</i> as a sister group to multiporate ctenostomes. Divergence time estimation and ancestral state reconstruction recover the solitary state of <i>M. ambulans</i> as a derived character that probably evolved in the Late Cretaceous. In this study, we also provide the entire mitogenome of <i>M. ambulans</i>, which—despite the momentary lack of comparable data—provides important data of a unique and rare species for comparative aspects in the future.<h3>Conclusions</h3>We were able to provide first sequence data and modern morphological data for the unique bryozoan, <i>M. ambulans</i>, which are both supporting an alcyonidioidean relationship within ctenostome bryozoans.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Rediscovering the unusual, solitary bryozoan <i>Monobryozoon ambulans </i>Remane, 1936: first molecular and new morphological data clarify its phylogenetic position","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-12 01:32:25.361101","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Heligoland, Solitary, Phylogenetic relationship, Solitary bryozoa, Mitogenome","OtherDescriptors":null,"Notes":null,"AnaPub":2024,"MonPub":null,"DateUpdate":"2024-03-18","DateCreate":"2024-03-18","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":1,"DOI":"10.1186/s12983-024-00527-1"},"refs":null,"anarec":{"AnaID":391142,"PubliDate":2024,"Pagination":"5","XtraPublOfAnaID":null,"ISBN":null,"Volume":"21","Issue":"1","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":217801,"SerRR":"Frontiers in Zoology.
