生態學
海洋 礁區魚類; 非遷移的; 深度上下限 ? - 40 m (Ref. 9710). 熱帶; 30°N - 30°S, 33°E - 93°E
Indian Ocean: including the Red Sea and the Persian Gulf south to Durban, South Africa, then east to North Bay Reef, Andaman and Nicobar Islands. Reports of this species elsewhere are probably due to misidentification.
西印度洋: 包括紅海與波斯灣到留尼旺島。 這種其他地方的報告是可能由於錯誤的鑑定。
Length at first maturity / 大小 / 重量 / 年齡
Maturity: Lm 21.3 range ? - ? cm
Max length : 40.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 2295); common length : 25.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 2295)
背棘 (總數) : 10; 背的軟條 (總數) : 9; 臀棘: 3; 臀鰭軟條: 8. The inner surface of the pectoral fin base is densely scaled; posterior angle of the operculum is fully scaled; cheeks without scales. Color of body is dark gray or yellow-brown, head is brown-gray. The centers of scales are lighter. Sometimes there is an irregular pattern of broken dusky bars becoming whitish on the lower part of the body. The pectoral and pelvic fins are white of pinkish. The dorsal and anal fins are mottled white or yellowish with reddish edge. The caudal fin has indistinct reddish bands.
胸鰭基底的內面覆滿鱗片; 鰓蓋的在後部角是完全覆蓋著鱗片; 頰沒有鱗片。 身體顏色較深灰色的顏色或黃褐色, 頭部是褐灰色的。 鱗片中央是顏色淡的。 有時有在身體的下面部份上變成微白色的一個斷掉暗色的條紋不規則圖案。 胸鰭與腹鰭是白色的略帶桃色的。 背鰭與臀鰭有白色斑點的或者淡黃色的有淡紅的色彩邊緣。 尾鰭有不明顯的淡紅條紋。
Found in sandy areas near reefs during daytime, sometimes in small groups. At night, they are solitary and range over reef-flats and slopes where they feed primarily on echinoderms, mollusks and crustaceans (Ref. 2295). The taxonomy of this species has been considerably confused.
發現於礁區附近的沙地在白天期間了, 有時形成小群魚群。 在晚上，他們是獨居性的而且排列礁石平臺之上與斜坡在那裡它們主要捕食棘皮動物，軟體動物與甲殼動物.(參考文獻 2295) 這種的分類學已經非常地被混亂。
