Head large; thick and fleshy lips; nostrils tubular. First dorsal fin high, with a strong serrated spine and 6 rays. Skin tough and smooth. Body coloration in adults vary from olive-green to brown, black or purplish dorsally and white ventrally. Urogenital papilla triangular in females; longer and cylindrical in males.
头部大的; 厚而肉质的唇; 鼻孔管状的。 第一背鳍很高, 具有一个强韧的锯齿状的棘与 6个鳍条。 皮肤强硬而平滑的。 身体颜色当成鱼时改变从橄榄绿色的到褐色的，黑色的或带紫色的背面与腹侧白色的。 泌尿生殖器的乳突三角形的在雌性中; 比较长与圆筒形的在雄性中。
Adults inhabit slow moving streams, lakes and ponds with fringing vegetation. They swim close to sand or gravel bottoms. More abundant in lakes than in flowing water (Ref. 44894). Usually solitary but juveniles sometimes form loose aggregations. Mainly bottom-feeders (Ref. 44894). Feed on insect larvae, prawns, crayfish, mollusks, and small fishes. Breeding occurs between spring and mid-summer when water temperatures rise to between 20° and 24°C (Ref. 44894). Utilized for human consumption.
用岸边的植丛栖息于缓慢移动的溪流 , 湖泊与池塘。 游泳接近沙子或砾石底部。 更丰富的在湖中超过在流动的水.(参考文献 44894) 通常独居性的但是稚鱼有时形成松散的鱼群。 主要地底部-捕食者.(参考文献 44894) 吃昆虫幼生，虾，小龙虾，软件动物与小鱼。 当水温隆起到 20个 ° 与 24 °C 之间的时候，在春天与夏季中旬之间繁殖。 (参考文献 44894) 供人类食用。
Life cycle and mating behavior
成熟度 | 繁殖 | 产卵场 | 卵 | 孕卵数 | 仔鱼
Water temperature (20-24 °C) considered the primary spawning stimulus. There is direct pairing during spawning. Male builds nest (0.6-2.0 m in diameter) and cares for eggs in the nest up to 2 weeks. The nest is made of gravel and rocks with a central sandy depression in which the female deposits up to 20,000 eggs depending on her size (Ref. 5259). Eggs scattered into the rubble are tended and guarded by the male after the female departs (Ref. 205). Hatching occurs in 7-10 days at 18°C (Ref. 240).大洋洲: 澳洲的特有種。
