Gill rakers on first gill arch 7-8 + 15-18 = 22-26; last soft ray of both dorsal and anal fins well
produced, longer than next to last ray; caudal fin forked; pectoral fins long, about equal to or somewhat shorter than head length; membranes of dorsal and anal fins without scales; tubed
lateral-line scales 57-62. Colour variable, ranging from brownish to lavender or reddish
purple; snout and interorbital space with narrow yellow lines and blue spots often persisting as dark spots when preserved; dorsal and caudal fins light blue or lavender with reddish orange margins (Ref. 9821).
眼間隔平坦的。 下頜些微地伸出。 胸鰭長的, 達到肛門高度。 背鰭基底與臀鰭沒有鱗片,他們的最後軟鰭條在短的絲狀突起延伸了。 鱗片列背面平行於側線。 背面與側邊的顏色改變從褐色的對淡紫色或淡紅的紫色; 吻部與眼間隔有狹窄的黃線與藍色的斑點; 背鰭與尾鰭淺藍色或淡紫色的與橘紅色邊緣。
Adults occur over rocky bottoms (Ref. 30573); off Guam, caught most abundantly between 180 and 270 m (Ref. 9821). At night, they migrate vertically to the upper part of its habitat to feed (Ref. 11888). They feed on small fishes, shrimps, crabs, amphipods, ascidians and salps. Marketed fresh (Ref. 55). Caught mainly with bottom longlines and deep handlines, marketed main fresh and a good quality food fish (Ref. 9821).
