Morphology | Morphometrics
soft rays: 82 - 88;
Vertebrae: 60 - 64. This species is distinguished and differs from B. walkeri by its long lateral line, snout to end of lateral line 64-80% SL (vs. 39.5% SL) and ending below dorsal fin ray number 47-69 (vs. 10) and above vertebra number 31-43 (vs. 12); scales in midline of body 130-150 (vs. 175); distance between base of pelvic fins and anal fin origin 24.0-32.5% SL (vs. 34.5% SL); two median basibranchial tooth patches, the anterior short and broad (vs. long and narrow); scale rows between origin of dorsal fin and lateral line 7-8 (vs. 11); sagitta thin, 12-16% its height (vs. 23% its length) (Ref. 86400).
Uncommon species (Ref. 34024). Oviparous, with oval pelagic eggs floating in a gelatinous mass (Ref. 205).

Estimates based on models
Preferred temperature (Ref. 115969
): 2.5 - 7.4, mean 4.6 °C (based on 889 cells).
Phylogenetic diversity index (Ref. 82805
= 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00110 (0.00040 - 0.00300), b=3.08 (2.85 - 3.31), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.7 ±0.6 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Moderate to high vulnerability (55 of 100) .
