Here we present evidence of contemporary bioerosion of cold-water coral by four species of deep-sea echinoids, <i>Gracilechinus elegans, Gracilechinus alexandri, Cidaris cidaris</i>, and <i>Araeosoma fenestratum</i>, showing that they actively predate on the living framework of reef building corals, <i>Lophelia pertusa</i> and <i>Madrepora oculata</i>, in the NE Atlantic. Echinoid specimens were collected in six canyons located in the Bay of Biscay, France and two canyons on the north side of the Porcupine Bank and Goban Spur, Ireland. A total of 44 live specimens from the four taxa (9 of G. <i>elegans</i>, 4 of G. <i>alexandri</i>, 21 of <i>C. cidaris</i> and 10 of <i>A. fenestratum</i>) showed recent ingestion of the coral infrastructure. Upon dissection, live coral skeleton was observed encased in a thick mucus layer within the gastrointestinal tract of <i>G. elegans</i> and <i>G. alexandri</i> while both live and dead coral fragments were found in <i>C. cidaris</i> and <i>A. fenestratum</i>. Echinoid bioerosion limits the growth of shallow-water reefs. Our observations suggest that echinoids may also play an important role in the ecology of deep-water coral reefs.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Evidence for the bioerosion of deep-water corals by echinoids in the Northeast Atlantic","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-05-28 01:31:19.517870","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Echinoid; Bioerosion; Gut content; Deep-sea coral; Lophelia pertusa; Madrepora oculata; NE Atlantic; Bay of Biscay; Porcupine Bank","OtherDescriptors":null,"Notes":null,"AnaPub":2013,"MonPub":null,"DateUpdate":"2018-02-13","DateCreate":"2017-08-09","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000314201100007","VABBcode":null,"OpenAcc":0,"DOI":"10.1016/j.dsr.2012.09.005"},"refs":null,"anarec":{"AnaID":287771,"PubliDate":2013,"Pagination":"73-78","XtraPublOfAnaID":null,"ISBN":null,"Volume":"71","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":45506,"SerRR":"Deep-Sea Research, Part I.
