Краткое описание
определительные ключи | морфология | морфометрия
колючие лучи спинного плавника (общее число) : 0; членистые (мягкие) лучи спинного плавника (общее число) : 10 - 11; колючие лучи анального плавника: 0; членистые (мягкие) лучи анального плавника: 9 - 11; позвонки: 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.
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).
