Frequently occurs in counter current zones of principal rivers and creeks. Feeds mainly on fish but also on other animals that fall into the water like small terrestrial invertebrates. Is active at dusk and at night. Reproduction takes place at the onset of the rainy season from December to March. Depending on the size, the female can carry around 6,000 to 60,000 eggs (Ref. 12225). Known for the quality of its flesh (Ref. 27188).
时常出现于主要河与小溪的逆流区中。 主要吃鱼也捕食其他的掉入水中相似的小陆栖的无脊椎动物的动物。 在薄暮是活跃的而在夜晚。 繁殖发生在雨季的开始从十二月到三月。 依据大小而定, 母鱼能运送大约 6,000 到 60,000个卵。 (参考文献 12225) 以它的肉的品质闻名。 (参考文献 27188)
