Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 104; Anal soft rays: 82; Vertebrae: 59. This species is distinguished and differs from B. gillii by its short lateral line, snout to end of lateral line 39.5% SL (vs. 64-80% SL) and ending below dorsal fin ray number 10 (vs. 47-69) and above vertebra number 12 (vs. 31-43); scales in midline of body 175 (vs. 130-150); distance between base of pelvic fins and anal fin origin 34.5% SL (vs. 24.0-32.5% SL); two median basibranchial tooth patches, the anterior long and narrow (vs. short and broad); scale rows between origin of dorsal fin and lateral line 11 (vs. 7-8); sagitta thick, 23% its length (vs. 12-16% its height (Ref. 86400).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.7 ±0.6 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (45 of 100).
