The specimens examined possessed bent over, overlapping scales that characterize the outer surface of right valve of the holotype of C. cerion, and these characteristic scales were also found in the left valve. On the other hand, these characteristic scales were not found in a paratype examined in this study. This indicates that at least one paratype is not conspecific to the holotype and they seem to consist of more than two species, including a potentially undescribed species. All the specimens of C. cerion from the Ryukyu Islands have been found in anchialine environments of submarine caves (darkness and low salinity conditions), and these records represent the first definite findings of living individuals of C. cerion.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_1617186643794":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_1522300295150":"ja","subitem_1522300316516":"琉球大学資料館 (風樹館)"}]},"item_1617186702042":{"attribute_name":"Language","attribute_value_mlt":[{"subitem_1551255818386":"eng"}]},"item_1617186920753":{"attribute_name":"Source Identifier","attribute_value_mlt":[{"subitem_1522646500366":"EISSN","subitem_1522646572813":"2187-6657"}]},"item_1617186941041":{"attribute_name":"Source Title","attribute_value_mlt":[{"subitem_1522650068558":"ja","subitem_1522650091861":"Fauna Ryukyuana"},{"subitem_1522650068558":"en","subitem_1522650091861":"Fauna Ryukyuana"}]},"item_1617187056579":{"attribute_name":"Bibliographic Information","attribute_value_mlt":[{"bibliographicIssueDates":{"bibliographicIssueDate":"2022-04-07","bibliographicIssueDateType":"Issued"},"bibliographicPageEnd":"73","bibliographicPageStart":"65","bibliographicVolumeNumber":"64"}]},"item_1617258105262":{"attribute_name":"Resource Type","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_1617605131499":{"attribute_name":"File","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2022-04-25"}],"filename":"64-6.pdf","filesize":[{"value":"8.6 MB"}],"url":{"objectType":"fulltext","url":"https://u-ryukyu.repo.nii.ac.jp/record/2017919/files/64-6.pdf"},"version_id":"7cb7caf0-bb9c-403c-a80a-c9c268fff0e6"}]},"item_title":"琉球列島の海底洞窟におけるハチノスキクザル (軟体動物門二枚貝綱キクザルガイ科) の生貝記録","item_type_id":"59","owner":"14","path":["1650872017517","1642838412624"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2022-04-25"},"publish_date":"2022-04-25","publish_status":"0","recid":"2017919","relation_version_is_last":true,"title":["琉球列島の海底洞窟におけるハチノスキクザル (軟体動物門二枚貝綱キクザルガイ科) の生貝記録"],"weko_creator_id":"14","weko_shared_id":-1},"updated":"2022-04-25T08:35:22.731299+00:00"}
