簡短描述 檢索表 | 型態特徵 | 形態測量圖

背棘 (總數) : 10; 背的軟條 (總數) : 9; 臀棘: 3; 臀鰭軟條: 8. The only Lethrinus with its 2nd dorsal spine the longest. The inner surface of the pectoral fin may be scaleless, partially covered with scales or densely covered with scales. Body color is tan or brown on the upper sides, white on the lower sides, with three tan or brown stripes. The sides often have scattered irregular black oblique bars and a square black blotch above the pectoral fin and bordering below the lateral line. The head is brown or tan sometimes with several broad, somewhat indistinct vertical and oblique bands (these bands are sometimes composed of fine reticulations). The fins are pale, speckled with small white blotches.
唯一的龍占魚科魚類用它的第二背鰭棘最長的。 胸鰭的內面可能是無鱗片的, 部份地覆蓋著鱗片或者濃密地覆蓋著鱗片。 體色在上側面上是黃褐色或者褐色, 白色的在下面的側邊上, 有三條黃褐色或褐色斑紋。 側邊時常有分散的不規則的黑色斜紋與在胸鰭上面的一個方形的黑色斑塊而且在側線之下毗鄰。 頭部是褐色或者黃褐色的有時有一些寬的, 略微不明顯的垂直且斜的條紋.(這些條紋有時被由細網眼組成) 鰭是灰白的,有小的白色斑塊的斑點。

生物學特性     字彙 (例如 epibenthic)

Solitary or in groups (Ref. 90102). Occurs over shallow sandy and seagrass beds, in mangrove swamps, lagoons, channels and outer reef slopes. May enter rivers. Feeds on crustaceans and small fishes. A protogynous hermaphrodite (Ref. 55367). A protracted spawning peak from July to December is recorded in New Caledonia. Smaller and more numerous females than males have been confirmed in Australian populations. Marketed fresh (Ref. 9775).

在紅樹林沼澤,潟湖,峽道與外礁斜坡中, 生活在水淺的沙地與海草床之上。 可能進入河。 吃甲殼動物與小魚。 一個雌性先熟的雌雄同體.(參考文獻 55367) 伸長的產卵顛峰從七月到十二月在新加勒多尼亞被記錄。 小而眾多的雌性超過雄魚有在澳洲的族群被確認。 在市場上銷售生鮮地了。 (參考文獻 9775)
