The new species was further observed during eight remotely operated vehicle (ROV) dives along the Mauritanian slope southwards down to the Tiguent Coral Mound Complex (~17° N) in a bathymetric range between 613 and 416 m. It can be distinguished from congeners by a combination of characteristics, including large eyes (38.1% head length [HL]), large head (25.8% standard length [SL]), elongated pelvic fins (35.7% SL), low number of vertebrae (44), and coloration (pinkish with a dorsal darker brownish hue and bright blotches along the dorsal-fin base). A species-delimitation analysis performed with available cytochrome c oxidase subunit 1 (<i>COI</i>) sequences affiliated to the genus <i>Gaidropsarus</i> additionally supported the validity of the new species. Video analyses showed a deep-water coral-associated and protection-seeking behavior, which may explain why the species has remained undescribed until now. Additional ROV footage from separate deep-water coral sites in the North Atlantic and Mediterranean Sea further highlights the ecological behavior and hidden diversity of bathyal three-bearded rocklings. Here, we additionally discuss the biogeographical distribution of all genetically verified <i>Gaidropsarus</i> spp. in combination with genetic data and morphological characters. <i>G. mauritanicus</i> sp. nov. is closely related to a species from Tasmania (43° S), a geographical point furthest among the studied samples, which may hint to an important influence of (paleo-) oceanography on the distributions of <i>Gaidropsarus</i> species.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"<i>Gaidropsarus mauritanicus</i> (Gadiformes, Gaidropsaridae) a new three‐bearded rockling from a deep‐water coral ecosystem with a genetically verified biogeographical distribution of the genus and notes to its ecology and behavior","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-10 01:33:01.355738","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2024,"MonPub":null,"DateUpdate":"2025-07-08","DateCreate":"2025-07-08","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":1,"DOI":"10.1111/jfb.15859"},"refs":null,"anarec":{"AnaID":409715,"PubliDate":2024,"Pagination":"1643-1665","XtraPublOfAnaID":null,"ISBN":null,"Volume":"105","Issue":"6","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43231,"SerRR":"Journal of Fish Biology.
