Short description Identification keys | Morphology | Morphometrics

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).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = No PD50 data   [Uniqueness, from 0.5 = low to 2.0 = high].
Trophic level (Ref. 69278):  4.0   ±0.7 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  Very Low, minimum population doubling time more than 14 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  High to very high vulnerability (68 of 100).
