眼間隔平坦的。 下頜些微地伸出。 背鰭基底與臀鰭沒有鱗片,他們的最後軟鰭條延伸到短的絲狀突起內了。 胸鰭長的, 達到肛門高度。 鱗片列背面平行於側線。 身體是銀色的有淡紫色的色; 頂端那頭部有深色斑點; 背鰭的邊緣橘色的; 尾鰭帶紫色的與叉子的內緣灰白的。
Adults are found over rocky bottoms (Ref. 30573); off Guam, caught most abundantly from about 180 to 270 m (Ref. 9821). They feed mainly on fishes, shrimps, crabs, polychaetes, cephalopods and urochordates. Marketed mostly fresh. Caught mainly with bottom longlines and deep handlines.
生活在岩石底部之上;(參考文獻 30573) 外海的關島, 捕獲量最大從大約 180 到 270 公尺了。 (參考文獻 9821) 主要吃魚，蝦，螃蟹，多毛類動物，頭足類動物與海鞘類。 市場上大部份生鮮地銷售。 主要地以底部延繩釣且深手執的釣絲捕捉。
