Maturity: Lm ? range ? - ? cm
Max length : 88.0 cm FL 雄魚/尚未辨別雌雄; (Ref. 40637); 最大體重: 6.0 kg (Ref. 54653)
背棘 (總數) : 0; 背的軟條 (總數) : 10 - 11; 臀棘: 0; 臀鰭軟條: 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.
背鰭基底的地點明顯地位於前垂直的經過臀鰭起源除了 B. lucius 與 B. xyrekes 以外將此種與所有的 ctenoluciids 區分開, 從它在尾鰭鰭條的基部部分上鑑別的特徵是不連續的黑色斑點, 以及藉著不同顏色在身體上。
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).
