Max length : 66.0 cm SL 雄魚/尚未辨別雌雄; (Ref. 44894); 最大體重: 4.5 kg (Ref. 6390); 最大年齡: 14 年 (Ref. 56606)
Inhabitant estuaries, coastal rivers, creeks, lakes and bays, usually in marine or brackish water, but in dry seasons they penetrate the lowermost reaches of fresh water (Ref. 44894). Common in coastal and estuarine rocky habitat. They enter rivers upstream to the limit of brackish waters. They migrate from their feeding to their spawning grounds; they spawn mainly during winter in the vicinity of river entrances; eggs are planktonic and hatch after 2.5 days. A portion of the population changes sex from male to female after spawning. They feed on mollusks, crustaceans, worms, fish and ascidians. It is parasitised by the monogeneans Anoplodiscus australis and A. spari on the fins and body surface (Ref. 124057).
常見於海岸而河口的岩石棲息地。 他們進入河溯河到半鹹淡水的極限。 他們從他們的覓食場到產卵場移動; 他們在冬天期間主要地在鄰近河入口產卵; 卵是浮游性而且在 2.5 天之後孵化。 性別轉變的族群之一從雄魚到母魚在產卵之後。 他們吃軟體動物，甲殼動物，蠕蟲，魚與海鞘類。

A proportion of the population change sex from male to female after their first spawning season (Ref. 6390). Other fish remain functional males throughout their life and another small proportion develop directly into females at the age of 4 years (Ref. 27246, 28262). Also Ref. 28504.
The eggs and larvae are planktonic (Ref. 30572). After about four weeks the developed fry enter the estuary at night on the full moon and settle in estuarine littoral areas at about 1.4 cm in length (Ref. 30572). The fry rapidly develop into juveniles and grow to about 10 cm after one year (Ref. 30572).西南太平洋: 澳洲東部的特有種, 從在昆士蘭省到維多利亞的吉斯蘭湖的敦斯維。 在日本與琉球群島 (參考文獻 559) 與台灣 (參考文獻 5193) 的發生需要確認。
