The Yellow-dotted Butterflyfish, ''Chaetodon selene'', is a poorly known fish species which has been recorded in the Indo-Pacific region from Malaysia, Indonesia, New Guinea, Taiwan and Japan.〔 "Chaetodon selene, Yellow-dotted butterflyfish : fisheries", FishBase (2010), link: (FB634 ).〕 It grows to a maximum of long. The body is mainly white, with a series of yellow dots running at diagonal lines over the sides (''see photo''). A black band extends from the caudal peduncle along the bases of the dorsal and anal fins. There is a narrow black eyestripe edged with yellow.〔 ''C. selene'' belongs to the large subgenus ''Rabdophorus'', which might warrant recognition as a distinct genus. In this group, it appears a somewhat distant relative of the Black-backed Butterflyfish (''C. melannotus'') and the Spot-tailed Butterflyfish (''C. ocellicaudus''). They are all of oval shape, silvery with yellow fins and snout, ascending diagonal stripes (yellow in ''C. selene'', dark in the others), and black markings around the eyes, on the caudal peduncle, and sometimes on the back. Next closest seem the Saddle Butterflyfish (''C. ephippium'') and the Dotted Butterflyfish (''C. semeion''), but these are already so distant that their ancestors are thought to have diverged from those soon after the ''Rabdophorus'' lineage started to diversify.〔Fessler & Westneat (2007), Hsu ''et al.'' (2007)〕 The Yellow-dotted Butterflyfish is found on coastal reefs, primarily on rubble slopes from in depth. It feeds on benthic invertebrates.〔 ==Footnotes== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Yellow-dotted butterflyfish」の詳細全文を読む スポンサード リンク
