简单描述
型态特徵 | 形态测量图
Diagnosis: large, big-toothed brownish species; eyes rather large; premaxillary pedicel relatively short (Ref. 55949).
鉴别: 大的, 大的-有齿的褐色种; 眼相当大; 上颌骨前的茎相当短的.(参考文献 55949)
描述: 嘴与眼相当大; 通常有向下弯曲的吻; 下颌一般到强烈地凸出; 较大的标本倾向有一个弓形的背面与一个松软的, 相当圆形的低轮廓; 上颌骨前的茎硬骨可变的长, 通常短于在 similary 规模 R. woodi 中; 齿非常强与细长的但是可变的.(参考文献 55949)

Common on the shelf zone; occasionally found off reefs; but not commonly recorded from the middle of the lake (Ref. 55949). Moves in the open water but stays 2-5 m above the substrate; feeds on fish like the small Utaka and Usipa (Engraulicypris sardella) (Ref. 5595).
常见于大陆棚区域; 偶然地发现外海的礁; 但是不通常记录了湖的从中央.(参考文献 55949) 在开放水域中的移动但是停留 2-5个公尺上方底部; 吃像小的 Utaka 与 Usipa( 沙丁鳀波鱼〔Engraulicypris sardella〕 ) 的鱼。 (参考文献 5595)
