Short description Chiavi di identificazione | Morfologia | Morfometria

This large species (to at least 112.6 cm TL) with a rhombic disc, is distinguished from other Peruvian species (as well as all other southeast Pacific congeners) by the following characters: a uniform black-to-chocolate or dark-plumbrown colouration, notably the same on both dorsal and ventral surfaces (vs. dorsal and ventral surfaces of different colors, except B. aguja; an irregular spotted pattern on both dorsal and ventral surfaces (vs. no spotting or, in B. aguja, two symmetrically arranged, large, white spots on dorsal surface at pectoral-fin bases and symmetrically arranged white spots along disc margins); differs from Peruvian congeners by having more precaudal vertebrae 79-81 (vs. 62-71); fewer pectoral-fin radials 69-70 (vs. 72-83) (Ref. 127873).
