簡短描述 型態特徵 | 形態測量圖

背棘 (總數): 0; 背的軟條 (總數): 85-94; 臀鰭軟條: 64 - 74. Dorsal fin origin closer to tip of snout than to anterior edge of eye. Dorsal and anal fins terminate just a little on the blind side of the caudal peduncle. Lateral line forms a distinct curve above the pectoral fin. Dorsal and anal fin with indefinite darker spots posteriorly.
背鰭起點更靠近吻尖超過對眼的前緣。 背鰭與臀鰭在尾梗的沒有眼睛的一邊上正好稍微結束。 側線形成一個在胸鰭上面的明顯彎曲。 背鰭與臀鰭在後部地有模糊的較黑的斑點。

生物學特性     字彙 (例如 epibenthic)

Adults occur on soft bottoms. Depth range from 100-400 m (Ref. 06302) and from 288-700 m in the eastern Ionian Sea (Ref. 56504). Feed on small bottom-living fishes as well as squids and crustaceans (Ref. 4703). Spawning occurs in deep waters off Iceland and west of the British Isles (Ref. 35388).

生活於軟質底部。 吃小型底棲性魚以及烏賊與甲殼動物。 (參考文獻 4703) 產卵在深的水域外海的冰島與位於英國島西方.(參考文獻 35388)
