The median one is usually black extending from the snout and via the eye to the base of the tail. The second one, paler lateral stripe further below. The upper stripe incorporates a bicolored (green and yellow turning later to black) spot where it crosses the edge of the gills (this is present in all phases).〔 Intermediates vary greatly, from shades of light purple to dark brown. Juveniles are usually white and have two dark stripes, but the lower (abdominal) stripe may be faint.〔(Smithsonian Tropical Research Institute Bocas del Toro Species Database )〕 3- The juvenile phase, the body is usually whitish still with the two longitudinal stripes and the spot up to the pectoral fin like in the initial phase.〔http://species-identification.org/species.php?species_group=caribbean_diving_guide&id=258〕 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「Slippery dick」の詳細全文を読む スポンサード リンク
