生態學
海洋 深海區的; 深度上下限 0 - 1800 m (Ref. 58018). 深水域
Eastern Atlantic: France to Morocco; off the Cape, South Africa (Ref. 6592). Also known from temperate and subtropical latitudes of the western Atlantic, southwestern Indian, and southwest Pacific.
東大西洋: 法國到摩洛哥; 外海的南非開普省.(參考文獻 6592) 也已知來自大西洋西部，西南印度洋與西南太平洋的溫帶與亞熱帶緯度。
大小 / 重量 / 年齡
Maturity: Lm ? range ? - ? cm
Max length : 60.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 123983)
背棘 (總數) : 0; 臀棘: 0. Dark brown in color (Ref. 6592). Snout long, depressed, and spatulate in form; lateral line distinct; pectoral fin long, subequal to snout; dorsal and anal fin rays abruptly become shorter near tip of tail and once again become longer, so it appears an independent caudal fin is present (Ref. 13608).
深褐色的顏色.(參考文獻 6592) 吻長的﹐扁平的﹐與竹片狀的形式; 側線明顯的; 胸鰭長的, 幾乎等於吻; 背鰭棘條與臀鰭棘條突然地變得比較短的接近尾尖時而且再一次變得比較長的，因此，它出現一個獨立的尾鰭存在.(參考文獻 13608)
Mesopelagic (Ref. 5951). Feeds mainly on crustaceans.
