背棘 (總數) : 10; 背的軟條 (總數) : 9; 臀棘: 3; 臀鰭軟條: 7. Suborbital spine absent. Preopercle with 3 transverse scale rows. Pectoral fins long, reaching almost to level of origin of anal fin. Pelvic fins moderately long, reaching beyond anus. A line drawn upwards from the posterior edge of suborbital reaching the dorsal profile in front of origin of dorsal fin.

眶下骨棘不存在。 前鰓蓋骨有 3 橫跨的鱗片列。 胸鰭長的, 幾乎到臀鰭起點的水平。 腹鰭中等長度的, 超過肛門。 一條線以上從眶下後緣在背鰭起點之前達到背部輪廓。 尾鰭上葉鐮刀狀與黃色的, 通常絲帶狀的當成魚時。 具有腋窩的鱗片。 顏色: 身體上半部略帶桃色的, 下面銀色的。
Found on sand or mud bottoms. Abundant in depths between 45 and 90 m, but larger fish generally occur in depths greater than 110 m. Larger fish feed mainly on crustaceans, fish and cephalopods. Young fish (< 12 cm) eat copepods, ostracods and amphipods.
棲息於沙或泥底部了。 豐富的在深度介於 45 與 90 公尺之間, 但是較大的魚通常出現在深度大於 110 公尺。 較大的魚主要捕食甲殼動物，魚與頭足類動物。 幼魚 (<12 公分) 吃橈腳類的動物，介形蟲與片腳類動物。
