背棘 (總數) : 11; 背的軟條 (總數) : 25 - 29; 臀棘: 2; 臀鰭軟條: 7 - 8; 脊椎骨: 25. Swim bladder carrot-shaped with 31-42 arborescent appendages, the latero-anterior limb of appendages present throughout length of bladder; drumming muscles present only in males; urinary bladders rudimentary; sagitta elongate with pronounced bulge in posterior third of ventral margin; pectoral fin axillary fold naked; peritoneum unpigmented; anterior part of lateral line slightly curved.
泳鰾胡蘿蔔-形狀的具有 31-42個樹枝狀的附肢，附肢的後面-前面肢翼在膀胱的長度各處呈現; 鼓形肌只出現在雄性; 膀胱不發達的; 矢耳石延長在下緣的後面三分之一中有明顯的凸起; 胸鰭腋窩的羽翼摺疊裸露的; 腹膜沒有顏色; 側線的前部些微地彎曲。
Between the Kei River and Cape Agulhas, this species rarely enters estuaries or the surf zone, but becomes more abundant in the surf zone on the west coast of South Africa. Restricted to a depth of 1-20 m in Namibia, apparently due to anoxic conditions beyond this depth. Highly regarded as a table fish. Marketed mostly fresh, but sometimes frozen (Ref. 11025).
在 Kei 河與艾古哈斯角之間，這種很少進入河口或者海浪區, 但是在南非的西岸上的海浪區中變得更豐富的。 侷限於深度了單一 20 公尺的在那米比亞, 顯然地由於缺氧的環境超過這深度。 獲高度評價作為一個食用魚。 市場上大部份生鮮地銷售, 但是有時冷凍的.(參考文獻 11025) 先前報告如 A. hololepidotus 。
