简单描述
型态特徵 | 形态测量图
背棘 (总数): 0; 背的软条 (总数): 40-46; 臀鳍软条: 49 - 58; 脊椎骨: 62 - 63. Diagnosis: length of rayed dorsal fin 37-42% standard length; 40-46 dorsal-fin rays; length of adipose fin 22-27% standard length (Ref. 57129). No serrations on the anterior part of the pectoral spine (Ref. 270, 57129). Head oval-shaped to rectangular dorsally; snout broadly rounded; eyes rather laterally placed; frontal fontanelle long and narrow; occipital fontanelle relatively long and oval shaped; 'postorbital' bones completely united; suprabranchial organ well developed; pectoral spine smooth; openings of secondary sensory canals with regular geometric pattern (Ref. 270).
Coloration: preserved specimens: greyish-brown on back and sides, pale brown on belly; some specimens show a marbled colouration, particularly on posterior part of body; caudal fin often with one or more vertical cross-bars (Ref. 57129). Body and fins occasionally with irregularly placed spots (Ref. 270).
头部椭圆形的到矩形的背面; 吻宽广地圆的; 眼相当侧面地放置。 额骨囱门长而狭窄的; 后头骨囱门相当长而椭圆形的。 眼眶后的' 硬骨完全地联合了。 鳃前的器官发展良好的。 胸棘平滑的。 第二感觉管的开口具有规则的几何学的图案。 身体与鳍偶然地有不规则的放置斑点。
Facultative air-breathing (Ref. 126274); Hardly anything is known about the biology of this species (Ref. 78218). Maximum reported size for West Africa: 800 mm TL (Ref. 57129).
