生态学
海洋; 半咸淡水 礁区鱼类. 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.

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).
头部略圆的, 它的背面轮廓逐渐地弯曲。 眶前骨宽的。 唇厚的; 颚骨延伸至大约眼睛中央水平或超过。 前鳃盖骨凹槽与疖瘤弱的。 鳞片列背面斜向上升在侧联机面。 在颊上的鳞片列 9 或 10. 暗灰色的背面与上侧面在下侧与腹面上的渐层色到微白色的粉红色。 在侧边上稚鱼有大约相等宽度的一系列交互淡色与深色横带。
