Southeast Atlantic: Cape Frio, Namibia south to the Agulhas Bank and east to East London in South Africa. Western Indian Ocean: Madagascar Ridge (33°S,44°E).
東南大西洋: 那米比亞的 Frio 岬南至阿古拉斯淺堆而且東至在南非的東倫敦。 西印度洋: 馬達加斯加脊.(33個 °S,44 ° E)
首次成熟时的长度 / 大小 / 重量 / 年龄
成熟度: Lm 47.8  range ? - ? cm
Max length : 115 cm TL 雄鱼/尚未辨别雌雄; (Ref. 27121); common length : 60.0 cm SL 雄鱼/尚未辨别雌雄; (Ref. 1371)
背棘 (总数) : 1; 背的软条 (总数) : 42 - 50; 臀棘: 0; 臀鳍软条: 38 - 41. Body more slender than other hakes. Head large, about 25 to 30% of SL. Gill rakers short and thick with blunt tips. Pectoral fin tips reaching to level of anal fin origin. Color is steel gray on back, grading to silvery white ventrally.
Body shape (shape guide): elongated; Cross section: oval.
身体更细长的超过其他的鳕鱼。 头部大的, 大约 25 到 30% SL。 鳃耙短与厚的与钝的顶端。 胸鳍顶端延伸到臀鳍起源的程度。 色彩是铁灰色的背面, 渐层色到腹面银白色的。
Found near the bottom. Feeds on fishes, mysids, euphausiids and squids. Young feed mainly on euphausiids, but the diet becomes polyphagous with growth. Cannibalism has been observed in larger individuals (Ref. 9583).
发现于靠近底部了。 吃鱼,糠虾,磷虾与乌贼。 幼鱼主要吃磷虾,但是食性随着成长变成多食症。 嗜食同类已经在较大的个体被观察。 (参考文献 9583)
