簡短描述 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 body is light tan or olive to brown, becoming lighter below. the centers of the scales are often lighter than the background color. The head, often, has several broad indistinct vertical and diagonal light and dark bands. Sometimes there are white spots below the eye. The posterior edge of the operculum is dark brown. An orange-yellow stripe is on the lower part of the side with two additional more faint orange-yellow stripes above and one below this stripe. The fins are whitish or tan, sometimes mottled.
身體顏色較淡黃褐色或橄欖色到褐色的, 變成腹面顏色較淡。 鱗片的中心顏色經常比背景顏色淡。 頭部,時常,有一些寬的不明顯的垂直與斜的淡色與深色的條紋。 有時有白色的斑點眼睛下面。 鰓蓋的後緣深褐色的。 在側邊的下面部份上的一條橘黃色的斑紋是在這一條斑紋之下有兩個附加的更模糊的橘黃色的斑紋上方與一。 鰭是微白色或黃褐色的, 有時有斑點的。

生物學特性     字彙 (例如 epibenthic)

Found over seagrass beds (Ref. 41878), sand and rubble areas of lagoons and reefs (Ref. 30573). Found singly or in groups (Ref. 9710). Juveniles on weedy reefs (Ref. 48635). Feed on mollusks, crustaceans, and echinoderms (Ref. 30573). One of the commonest lethrinids along the coast of east Africa (Ref. 4369). Marketed fresh (Ref. 9775).

Life cycle and mating behavior 成熟度 | 繁殖 | 產卵場 | | 孕卵數 | 仔魚

Gonochorism is inferred for this species as sizes of males and females overlapped and male gonad morphology is typical of secondarily derived testes (Ref. 103751). This may be supported further by the study of Ebisawa etal (2006) which characterised sexual pattern for this species as juvenile hermaphroditism indicating that sexual transition occurred before ovarian maturation, a case for non-functional hermaphroditism in Ref. 103751.印度-太平洋: 紅海而且東非到琉球群島,東加與美屬薩摩亞。
