成熟度: Lm ? range ? - ? cm
Max length : 88.0 cm FL 雄鱼/尚未辨别雌雄; (Ref. 40637); 最大体重: 6.0 kg (Ref. 54653)
背棘 (总数) : 0; 背的软条 (总数) : 10 - 11; 臀棘: 0; 臀鳍软条: 9 - 11; 脊椎骨: 48 - 49. The location of the dorsal fin base distinctly anterior to the vertical through the anal fin origin distinguishes this species from all ctenoluciids except B. lucius and B. xyrekes, from which it can be distinguished by the discrete black spot on the basal portions of the caudal fin rays, and also by different pigmentation on the body.
Body shape (shape guide): elongated.
背鳍基底的地点明显地位于前垂直的经过臀鳍起源除了 B. lucius 与 B. xyrekes 以外将此种与所有的 ctenoluciids 区分开, 从它在尾鳍鳍条的基部部分上鉴别的特徵是不连续的黑色斑点, 以及藉着不同颜色在身体上。
Usually inhabits areas with rapid water, always on the surface, behind obstacles like rocks and logs (Ref. 54653). Some small-sized individuals occur in calmer waters such as lakes, small bays (Ref. 54653). Solitary or forms small schools (Ref. 54653). A carnivorous fish with preference on fish (Ref. 54653).
