简单描述
检索表 | 型态特徵 | 形态测量图
Big mouth, upper jaw extend trailing edge of eye. High body, side flat, backside with ridges. Anomalistic macula and dark spots on the sides; 4-5 dark horizontal stripes near the base of dorsal fin (Ref. 85820).
Adults inhabit rivers (Ref. 26334). Are demersal piscivores which have very specialized feeding habits--as soon as they start feeding, they feed solely on fry of other fish species. Typical of stalking predators, they rely on vision for following the movement of prey before leaping forward and snapping at the victim. Prey consist mostly of diurnal fishes whose eyes have color vision and high acuity but cannot function at night. The habitat of the Chinese perch is usually rich in macrophytes and might be very turbid during rainy season (Ref. 28033).
栖息于河。 (参考文献 26334) 已经非常特殊化的一个底栖的鱼食性食性--当它时开始进食, 它只吃其他鱼种的鱼苗。 典型的悄悄靠近掠食者，它为在跳跃向前地而且咬住受害者之前跟随猎物的运动仰赖视野。 它的猎物日行性鱼大部份组成 , 眼有色彩电野与高的锐敏但是不能够运作在晚上。 季花鱼的栖息地通常是丰富的在大型植物而且可能在雨季的时候非常浑浊.(参考文献 28033)
