Among marine mammals, a well-known example is krill-feeding crabeater seals (Lobodon carcinophaga), in which complex, comb-like postcanine teeth function as a sieve by retaining krill inside their mouth while expelling water. However, information on teeth morphology and function is scarce for other seal species. A recent bio-logging study found that Baikal seals (Pusa sibirica) feed on tiny pelagic amphipods at remarkably high rates with highly multi-cusped postcanine teeth, highlighting the need for comparative analyses on teeth morphologies and diets in phocid seals. Here, we quantified postcanine teeth morphology for 13 seal species based on museum skull specimens, with a particular focus on Baikal seals and their related species (genus Pusa and Phoca). The species in Pusa, including Baikal seals, had more specialized multi-cusped postcanine teeth than Phoca species, reflecting higher zooplankton proportions in their diets. Postcanine teeth of Baikal seals exhibited the highest degree of specialization among Pusa, even when the effect of age-related wear is controlled for. This result agrees with the highest zooplankton preference in this species. Further, we found a strong positive correlation between the degree of specialization in postcanine teeth and zooplankton reliance across phocid seal species. Our findings indicate that the functional role of multi-cusped postcanine teeth as a sieve is not limited to crabeater seals but prevail in many phocid seals feeding on zooplankton.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Inter-Research Science Publisher"}]},"item_10001_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.3354/meps14509","subitem_relation_type_select":"DOI"}}]},"item_10001_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"Inter-Research website(Abstract page)"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://www.int-res.com/abstracts/meps/v729/p233-245/","subitem_relation_type_select":"URI"}}]},"item_10001_source_id_11":{"attribute_name":"書誌レコードID (NCID)","attribute_value_mlt":[{"subitem_source_identifier":"AA10608952","subitem_source_identifier_type":"NCID"}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0171-8630","subitem_source_identifier_type":"PISSN"},{"subitem_source_identifier":"1616-1599","subitem_source_identifier_type":"EISSN"}]},"item_10001_version_type_20":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorAffiliations":[{"affiliationNames":[{"affiliationName":"Department of Polar Science, The Graduate University for Advanced Studies, SOKENDAI, Tachikawa, Tokyo 190-8518, Japan"},{"affiliationName":"Department of Evolutionary Studies of Biosystems, The Graduate University for Advanced Studies, SOKENDAI, Hayama, Kanagawa 240-0193 Japan"}]}],"creatorNames":[{"creatorName":"Ishihara, Uno","creatorNameLang":"en"},{"creatorName":"石原, 有乃","creatorNameLang":"ja"},{"creatorName":"イシハラ,　ウノ","creatorNameLang":"ja-Kana"}]},{"creatorAffiliations":[{"affiliationNames":[{"affiliationName":"Atmosphere and Ocean Research Institute, The University of Tokyo, Kashiwa, Chiba 277-8564, Japan"}]}],"creatorNames":[{"creatorName":"Miyazaki, Nobuyuki","creatorNameLang":"en"},{"creatorName":"宮崎, 信之","creatorNameLang":"ja"},{"creatorName":"ミヤザキ, ノブユキ","creatorNameLang":"ja-Kana"}]},{"creatorAffiliations":[{"affiliationNames":[{"affiliationName":"Arctic and Aquatic Research Division, Fisheries and Oceans Canada, 501 University Crescent, Winnipeg, Manitoba R3T 2N6, Canada"}]}],"creatorNames":[{"creatorName":"David J.
