背棘 (總數) : 3 - 7; 背的軟條 (總數) : 37 - 40; 臀棘: 0; 臀鰭軟條: 27 - 32. Caudal fin subtruncate or slightly rounded, emarginate in young. Coloration more spectacular compared to other nototheniids. Juveniles with a black blotch on distal end of pectoral fin.
Body shape (shape guide): fusiform / normal.
尾鰭子截形或略圓的, 邊緣微凹的當幼魚時。 顏色更壯觀的相較於其他的 nototheniids。 在胸鰭的末梢部末端上稚魚有一個黑色的斑塊。
Juveniles found in 1-10 m depth and possibly having a pelagic habit, adults in deeper water (Ref. 11892). Adults feed on crustaceans and fishes (Ref. 11892). Spawn once a year (Ref. 57661). Some information needs to be transferred from N. coriiceps to this species (RF).
稚魚發現於 1-10 公尺深了而且可能地有一個大洋性的習慣,成魚在較深的水域.(參考文獻 11892) 吃甲殼動物和魚類。 (參考文獻 11892) 一些訊息需要在從 N. coriiceps 到這種 (RF) 被轉移。
Mature females may spawn for the first time from around 6-8 years of age (Ref. 71843).南極海: 南極圈大陸,南極半島,南喬治亞州,雪特蘭群島南方部,奧克尼群島南方部島與彼得 I 島的海岸。
