Mesh sizes and filtering areas were measured utilizing an SEM. Among adult krill the filtering areas vary from 17.7 mm^2 in E. frigida to 276.8 mm^2 in E. superba. By applying sieve hypothesis, it is proposed that the presumptive lower limits of filterable particle sizes based on the morphology of fine filter meshes range 2-3 μm in E. superba, 8-11 μm in E. vallentini, 15-19 μm in E. frigida, 16-23 μm in E. crystallorophias and 27-39 μm in E. triacantha. In E. superba, the filter mesh sizes do not increase considerably with growth. In E. triacantha, the mean secondary setal distances increase from 28-37 μm to 41-56 μm. Species can be grouped according to the mesh sizes and filtering area; i) fine mesh filter feeder represented by E. superba; ii) medium mesh filter feeders such as E. vallentini, E. crystallorophias and E. frigida; and iii) coarse mesh filter feeder, E. triacantha. Potential food size spectra of these Euphausia species are discussed.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00005017","subitem_identifier_reg_type":"JaLC"}]},"item_1_publisher_22":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"National Institute of Polar Research"}]},"item_1_source_id_13":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AA10819561","subitem_source_identifier_type":"NCID"}]},"item_1_text_10":{"attribute_name":"著者所属(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Ocean Research Institute, University of Tokyo"},{"subitem_text_language":"en","subitem_text_value":"Ocean Research Institute, University of Tokyo"}]},"item_1_text_3":{"attribute_name":"記事種別(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Proceeding"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"1987-12-01"}],"displaytype":"detail","filename":"KJ00000767393.pdf","filesize":[{"value":"1.5 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000767393","url":"https://nipr.repo.nii.ac.jp/record/5017/files/KJ00000767393.pdf"},"version_id":"dfeb55a0-9956-471d-9e94-91256afd6565"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"COMPARATIVE MORPHOLOGY OF FILTERING STRUCTURE OF FIVE SPECIES OF EUPHAUSIA (EUPHAUSIACEA, CRUSTACEA) FROM THE ANTARCTIC OCEAN (Ninth Symposium on Polar Biology)","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"COMPARATIVE MORPHOLOGY OF FILTERING STRUCTURE OF FIVE SPECIES OF EUPHAUSIA (EUPHAUSIACEA, CRUSTACEA) FROM THE ANTARCTIC OCEAN (Ninth Symposium on Polar Biology)"}]},"item_type_id":"1","owner":"4","path":["637"],"pubdate":{"attribute_name":"公開日","attribute_value":"1987-12-01"},"publish_date":"1987-12-01","publish_status":"0","recid":"5017","relation_version_is_last":true,"title":["COMPARATIVE MORPHOLOGY OF FILTERING STRUCTURE OF FIVE SPECIES OF EUPHAUSIA (EUPHAUSIACEA, CRUSTACEA) FROM THE ANTARCTIC OCEAN (Ninth Symposium on Polar Biology)"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T12:15:19.974833+00:00"}
