タラ目サイウオ科サイウオBregmaceros japonicus Tanaka,1908の形態的特徴 Morphological characters of Bregmaceros japonicus Tanaka, 1908 : Gadiformes: Bregmacerotidae 鳥居, 聡尚 Torii, Akihisa 小澤, 貴和 Ozawa, Takakazu アントニーS.ハロルド Harold, Antony S. open access Bregmacerotidae Bregmaceros japonicus Validity Morphology This paper considers the validity and morphological characters of Bregmaceros japonicus Tanaka, Bregmacerotidae, based upon examination of the holotype and 37 specimens collected from eight areas along the Pacific coast of Japan. Reining confusion as to the identity and status of this species makes this redescription necessary. Morphology, including external features and osteology is described, based on the holotype and 12 non-type specimens. The holotype and the other specimens are completely identical in all of the characters examined. Comparisons with all other recognized species in the genus indicate that B. japonicus is valid. One particular feature, the position of the dorsal fin origin, which has been discussed in the literature as being diagnostic is not recognized as a diagnostic character of B. japonicus. This species appears to be most similar to, but distinct from, B. atlanticus in the number of transverse scales (14-15, compared with 11-13 in B. atlanticus). 鹿児島大学 Kagoshima University 2004-02-27 eng departmental bulletin paper VoR http://hdl.handle.net/10232/719 https://ir.kagoshima-u.ac.jp/records/1273 0453087X AN00040498 鹿児島大学水産学部紀要 Memoirs of Faculty of Fisheries Kagoshima University 52 43 50 https://ir.kagoshima-u.ac.jp/record/1273/files/KJ00004265798.pdf application/pdf 717.9 kB 2016-10-27 2004-02-27
