背棘 (总数): 10; 背的软条 (总数): 11; 臀棘 3; 臀鳍软条: 8. This species is distinguished by the following characters: body elongate, laterally compressed; jaws about equal or lower jaw protruding slightly; premaxillae protrusible. maxilla extending to vertical through about anterior margin of pupil; upper and lower jaws both with an outer row of conical to small canine teeth and an inner band of villiform teeth, the caniniform teeth at anterior ends of jaws are not appreciably enlarged; teeth on vomer triangular patch, maxilla without scales or longitudinal ridges; interorbital region flattened. 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).
眼间隔平坦的。 下颌些微地伸出。 胸鳍长的, 达到肛门高度。 背鳍基底与臀鳍没有鳞片,他们的最后软鳍条在短的丝状突起延伸了。 鳞片列背面平行于侧线。 背面与侧边的颜色改变从褐色的对淡紫色或淡红的紫色; 吻部与眼间隔有狭窄的黄线与蓝色的斑点; 背鳍与尾鳍浅蓝色或淡紫色的与橘红色边缘。
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).
生活在岩石底部之上;(参考文献 30573) 外海的关岛, 在 180 与 270 公尺之间捕获量最大了。 (参考文献 9821) 在晚上，它垂直地移动它的栖息地的到上半部觅食.(参考文献 11888) 吃小鱼，虾，螃蟹，片脚类动物，海鞘类与被囊动物。 在市场上销售生鲜地了。
