生態學
海洋; 半鹹淡水 礁區魚類. 熱帶; 7°N - 20°S, 15°W - 15°E (Ref. 55)
Eastern Atlantic: west coast of Africa (Ref. 57393), from Senegal to Angola (Ref. 81653), primarily in the Gulf of Guinea (Ref. 55, 57393, 81653), rarely appearing in Senegal (Ref. 57393). Mesoprion retrospinis Valenciennes, 1830 may be the oldest name for this species as the original description agrees closely to that given by Delais, 1952.
東大西洋: 塞內加爾到安哥拉。 主要地在幾內亞灣生存。 (參考文獻 55) Mesoprion retrospinis Valenciennes,1830 當最初的描述接近地同意，可能是最古老的名稱對於這個魚種那被 Delais 給,1952.

Scale rows on back rising obliquely above lateral line (Ref. 55, 57393, 81653). 4-5 scale rows above lateral line and below middle of spinous part of dorsal fin (Ref. 57393, 81653). 9-10 (transverse) scale rows on cheek (Ref. 55, 57393, 81653). Smokey gray on back and upper sides grading to whitish pink on lower sides and belly; sides of juveniles with a series of alternating light and dark bars of about equal widths (Ref. 55, 57393, 81653).
頭部略圓的, 它的背面輪廓逐漸地彎曲。 眶前骨寬的。 唇厚的; 顎骨延伸至大約眼睛中央水平或超過。 前鰓蓋骨凹槽與癤瘤弱的。 鱗片列背面斜向上升在側線上面。 在頰上的鱗片列 9 或 10. 暗灰色的背面與上側面在下側與腹面上的漸層色到微白色的粉紅色。 在側邊上稚魚有大約相等寬度的一系列交互淡色與深色橫帶。
Adults inhabit rocky bottoms and coral reefs (Ref. 55, 57393, 81653). Also common in brackish lagoons and occasionally in rivers (Ref. 55, 81653), especially juveniles (Ref. 57393). Feed on fishes and crustaceans (Ref. 55, 81653).
棲息於岩石底部與珊瑚礁。 也常見於半鹹淡的潟湖與有時在河中。 吃魚與甲殼動物。
