Morphology | Morphometrics
soft rays: 17 - 20;
Vertebrae: 35 - 36. 13-14 AO photophores; 8-10 tooth patches on the lower limb of the second gill arch; 34-35 lateral line organs (Ref. 36121). Pectoral fins relatively long and well developed in juveniles, progressively becoming relatively shorter, with thicker rays (covered by skin in various stages of becoming vestigial, between about 4-7 cm SL); vestigial rays buried in skin and not externally visible (Ref. 36121).

Estimates of some properties based on empirical models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00823 (-0.16321 - 0.17966), b=3.09 (2.99 - 3.19), based on LWR estimates for this family-BS (Ref. 93245
Trophic Level (Ref. 69278
): 3.2 ±0.4 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278
): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Moderate vulnerability (37 of 100) .
