Eastern Central Atlantic: Senegal to Gabon; also Cape Verde, São Tome-Principe Islands, and Rolas Islands. There is little doubt that only a single species of Lethrinus exists in the tropical western Atlantic.
中東大西洋: 塞內加爾到加彭; 也維德角，聖多美-普林西比島的島與 Rolas 島。 很少有懷疑哪一只有一個 龍占魚科魚類 的種在熱帶的大西洋西部中存在。

顎骨的外部表面是平滑的, 沒有癤瘤或明顯的縱向脊。 胸鰭葉腋的內面沒有鱗片。 整體的色彩是橄欖綠色或褐色與略帶桃色的。 頰部有一個細網眼眼睛下面的網絡。
Found in shallow coastal waters (Ref. 2263). Feeds mainly on bottom-dwelling invertebrates. Marketed fresh (Ref. 171), smoked and dried salted (Ref. 2295). Abundant during the winter months (Ref. 2683).
