Etymology: Nessorhamphus: Greek, nessa, netta = duck + Greek, rhamphos = bill, peak (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
生态学
海洋 深海区的; 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 / 年龄
Maturity: Lm ? range ? - ? cm
Max length : 60.0 cm TL 雄鱼/尚未辨别雌雄; (Ref. 123983)
背棘 (总数) : 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).
深褐色的颜色.(参考文献 6592) 吻长的，扁平的，与竹片状的形式; 侧线明显的; 胸鳍长的, 几乎等于吻; 背鳍棘条与臀鳍棘条突然地变得比较短的接近尾尖时而且再一次变得比较长的，因此，它出现一个独立的尾鳍存在.(参考文献 13608)
Mesopelagic (Ref. 5951). Feeds mainly on crustaceans.
