Nine species of metazoan parasites were found in H. melanophasma and seven in Chimaera sp. Four species were shared between both host species. Gyrocotyle sp.1 (Cestodaria) and Multicalyx elegans (Aspidogastrea) showed the higher prevalence H. melanophasma (68.3% and 65.38%, respectively), whereas Plectognathotrema hydrolagi (Digenea), Gyrocotyle sp.1 (Cestodaria), and Chimaericola sp. (Monogenea) showed higher prevalence in Chimaera sp. (90%, 55% and 55%, respectively). Beta diversity analysis reveals that the parasite communities of these two related and sympatric species are strongly differentiated. Our results suggest a strong relationship between the ancient Holocephali, which harbor ancient parasites belonging to Rugogasteridae and Multicalycidae (Aspidogastrea), and two Cestodaria species. Chimaera spp. are also parasitized by some highly specific monogeneans, such as Chimaericola spp. Our results demonstrate the differences in the parasite community structures—both of ecto- and endoparasites—of two related and sympatric hosts.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Metazoan parasite communities of two sympatric shortnose Chimeras (Holocephali: Chimaeridae) from deep waters associated with the Humboldt Current system: ancient fishes harbor ancient parasites","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2025-10-30 01:34:08.341815","timezone_type":1,"timezone":"+01:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"deep-sea chimaeras; parasites; Atacama Trench; Humboldt Current; beta diversity","OtherDescriptors":null,"Notes":null,"AnaPub":2025,"MonPub":null,"DateUpdate":"2025-10-23","DateCreate":"2025-10-23","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":1,"DOI":"10.3390/d17090601"},"refs":null,"anarec":{"AnaID":435580,"PubliDate":2025,"Pagination":"601","XtraPublOfAnaID":null,"ISBN":null,"Volume":"17","Issue":"9","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":239468,"SerRR":"Diversity.
