简单描述 型态特徵 | 形态测量图

背棘 (总数): 0; 背的软条 (总数): 56-62; 臀鳍软条: 50 - 58; 脊椎骨: 56 - 60. Characterized by a relatively long vomerine tooth plate (5.9-14.4 % HL) and by a relatively short adipose fin (5.9-12.5 % SL), the length of which is a specific character of C. ngamensis. Head oval to rectangular in dorsal outline; frontal fontanelle long and narrow (`knife-shaped'); occipital fontanelle small and oval-shaped. Pectoral spine robust and slightly curved. The suprabranchial organ consists of well developed arborescent structures.
特徵为一个相当长的犁骨齿碟 (5.9-14.4% HL) 与被一个相当短脂鳍 (5.9-12.5% SL), 长度是一个 C. ngamensis 的特定特徵. 头部椭圆形到矩形的在背部的轮廓中; 额骨囱门长而狭窄的;(刀状的') 后头骨囱门小而椭圆形的。 胸棘结实的而且些微地弯曲。 鳃前器官由发展良好的树枝状的结构组成。

生物学特性     字汇 (例如 epibenthic)

The species seems to be nowhere especially abundant but is fairly common in some areas such as weed beds, permanent swamps, quieter waters and muddy bottoms (Ref. 248, 5595). Prefers vegetated habitats. Feeding habits overlap considerably with the sharptooth catfish. Important foods are mollusks, terrestrial and aquatic insects, insect larvae, shrimps, grain, crabs and fish (Ref. 4967, 78218). Feeds on snails (Ref. 5595). Hard-shelled foods such as mussels are crushed before they are swallowed. Breeds during the summer rainy season. May live for 5-6 years (Ref. 7248). Also caught with drawnets (Ref. 4967).

也用拖网捕获。 (参考文献 4967) 在沼泽的区域中生活在泥底部上。 吃蜗牛。 (参考文献 5595) 偏爱长满植物的栖息地。 非常地和 sharptooth 鲶鱼进食习惯重叠。 重要的食物是软件动物,陆生与水生昆虫,虾,螃蟹与鱼。 具有硬壳的食物在他们被吞之前,例如贻贝被粉碎。 在夏天雨季期间进行繁殖。 可以活到 5-6 数年。 (参考文献 7248)
