簡短描述
型態特徵 | 形態測量圖
背的軟條 (總數): 4-6; 臀鰭軟條: 61 - 73. Head depressed; eyes small and located in anterior section of head; snout short; lower jaw longer than upper one and its end extending nearly to anterior edge of eyes; barbels 2 pairs, body naked. Body dark gray on back and sides, with cloudy streaks and milky white on belly.
頭部扁平的; 眼小的而且位於了頭部的前面部分; 吻短; 下頜比上頜長與它的末端對眼的前緣幾乎延伸; 觸鬚 2 對, 身體裸露的。 身體深灰色背面與側邊,在腹面上有雲狀的條紋與乳狀的白色。
This carnivorous species lives in the edge of the lake with plenty of waterweeds where it stays at bottom of water by day and comes out to the surface seeking food by dawn and dusk (Ref. 45563, 117912). It relies on the macrophytes for shelter, the disappearance of which from the lake exposed these big fishes in the shallow water which resulted to increased mortality from its natural enemy and human beings. Predation of eggs and juveniles by the introduced
species in the lake may also play an important role (Ref. 117912).
生活在湖的邊緣有豐富的水蘊草。 食肉動物。 白天停留在水的底部而且對被在破曉與薄暮之前尋找食物的表面出來。 (參考文獻 45563)
