简单描述
型态特徵 | 形态测量图
背的软条 (总数): 16-18; 臀鳍软条: 19 - 20
Inhabits still or flowing rivers, from tidal reaches to far inland. Also found in some impoundments (Lake Argyle,WA). Often shelters among overhanging vegetation or submerged roots. Adults are infrequently found in coastal marine waters (Ref. 44894). Occurs in larger streams. Surface-dwelling predator of small fishes, insects (Ref. 205, 44894) and crustaceans (Ref. 44894). Oviparous (Ref. 205). Spawning is believed to occur sometimes between September and December. The presence of juveniles well inland and in impoundments suggests that it may spawn in freshwater (Ref. 44894). Eggs may be found attached to objects in the water by tendrils on the egg's surface (Ref. 205).
栖息于静止的或流动的河, 从潮汐能达到的范围到远的内陆。 也发现于一些圈围水域。 (湖 Argyle,WA) 时常在上悬的植物或水下的根部之中隐匿。 成鱼是发现于稀少的海洋沿岸水域。 (参考文献 44894) 出现于较大的溪流。 小鱼，昆虫 (参考文献 205,44894) 与甲壳动物的居住在水面掠食者.(参考文献 44894) 卵生的.(参考文献 205) 产卵被相信在九月与十二月之间有时出现。 那有稚鱼相当深入内陆而且在圈围水域显示出它可能产卵于淡水中.(参考文献 44894) 卵可能被發現於在卵的表面上的捲鬚水依附於目標。 (參考文獻 205)
