The studied material includes that collected during expeditions aboard R/V <i>Professor Multanovskiy</i> in August–September 2019 and R/V <i>Dalnie Zelentsy</i> in August 2012. Additionally, the material of collections of the Zoological Institute of the Russian Academy of Sciences (Saint Petersburg) has been studied. The fauna of heterobranch molluscs of the order Cephalaspidea in the Kara Sea includes 18 described and 1 undescribed species that belong to 10 genera and 6 families. It has been specified that the type locality of <i>Retusa semen</i> Reeve, 1855 (Port Refuge) is located at Port Refuge National Historic Site of Canada, Devon Island, Nunavut, not in the Kara Sea. <i>Retusa semen</i> is considered here as <i>species inquirenda</i> because of the brief original description, significant differences in drawings of the shell of this species made by different authors, and the absence of type specimens. The presence of <i>Diaphana minuta</i> Brown, 1827, <i>Laona quadrata</i> (Wood, 1839), <i>Philine sinuata</i> Stimpson, 1851 and <i>Retusa semen</i> in the Kara Sea needs confirmation. Species numbers of heterobranch molluscs of the order Cephalaspidea decrease from the Barents Sea (21) through the Kara Sea (19) to the Laptev Sea (15) because of the decreasing proportion of boreal-arctic species. Among cephalaspids of the Kara Sea, the highest average abundance (individuals/m<sup>2</sup>) was observed for <i>Cylichnoides densistriatus</i> (Leche, 1878), and the highest average biomass for <i>Cylichna corticata</i> (Møller, 1842). The proportion of live individuals in the populations does not exceed 18% in late August – early September. The taxonomic structure of the cephalaspid fauna of the Kara Sea has been studied based exclusively on morphological characters. Further study of the fauna is needed based on molecular analyses of the material fixed in 96˚ alcohol.","AbstractOtherLang":"На основе материалов, собранных в Карском море во время рейсов НИС «Профессор Мультановский» в августе – сентябре 2019 г. и НИС «Дальние Зеленцы» в августе 2012 г., а также материалов коллекции, хранящихся в Зоологическом институте РАН (Санкт-Петербург), и литературных данных, обобще ны сведения о фауне и экологии заднежаберных моллюсков отряда Cephalaspidea в Карском море. Фауна цефаласпид Карского моря представлена 19 видами из 10 родов и 6 семейств, из которых один вид еще не описан. Уточнено, что типовое местонахождение <i>Retusa semen</i> Reeve, 1855 (Port Refuge), находится не в Карском море, как было указано в ряде публикаций и послужило основой указания этого вида в фауне Карского моря, а на севере Канадского арктического архипелага, на юге о. Девон. В связи с от-сутствием типового материала, очень кратким описанием и разноречивыми изображениями этого вида считаем его <i>species inquirenda</i>. Нахождение ранее указанных для Карского моря Diaphana minuta Brown, 1827, <i>Laona quadrata</i> (Wood, 1839), <i>Philine sinuata</i> Stimpson, 1851 и Retusa semen требует подтверждения. Количество видов заднежаберных моллюсков отряда Cephalaspidea уменьшается от Баренцева (21) к Карскому (19) и морю Лаптевых (15) за счет уменьшения доли атлантических бореально- арктических видов. Среди массовых видов отряда средняя плотность поселений в Карском море максимальна у <i>Cylichnoides  densistriatus</i>  (Leche, 1878),  а средняя биомасса максимальна у <i>Cylichna  corticata</i> (Møller, 1842). В конце августа – начале сентября доля живых особей в популяциях не превышает 18%. Анализ видового состава цефаласпид Карского моря осуществлен на базе исключительно морфологических признаков. Необходим дополнительный сбор материала с первичной фиксацией в 96° спирте для молекулярно-генетического анализа, что позволит уточнить список видов представителей отряда Cephalaspidea  изучаемого региона.","BibLvlCode":"AS","StandardTitle":"Shell-bearing mollusks of the order Cephalaspidea (Gastropoda: Heterobranchia) of the Kara Sea: fauna and ecology","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-14 01:32:01.879809","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Kara Sea; taxonomy; fauna; ecology; Cephalaspidae","OtherDescriptors":null,"Notes":null,"AnaPub":2021,"MonPub":null,"DateUpdate":"2021-11-29","DateCreate":"2021-11-18","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":1,"DOI":"10.31610/trudyzin/2021.325.2.197"},"refs":null,"anarec":{"AnaID":347409,"PubliDate":2021,"Pagination":"197-216","XtraPublOfAnaID":null,"ISBN":null,"Volume":"325","Issue":"2","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43982,"SerRR":"Trudy Zoologicheskogo Instituta Rossijskoj Akademii Nauk = Proceedings of the Zoological Institute Russian Academy of Sciences.
