Short description Morphology | Morphometrics

Dorsal spines (total): 9; Dorsal soft rays (total): 10; Anal spines: 3; Anal soft rays: 7. Second dorsal fin elongated, reaching just short of last dorsal fin ray when depressed (in all stages, up to 50% SL, mean 42% SL, tip very easily broken). Orbit diameter relatively small (8-11% SL), ratio as % of snout length, 93-143. Head length relatively short, 30-33% of SL. Maxillary reaching to below or (rarely) just short of anterior margin of iris. Exposed maxillary process always tapering to a point anteriorly for about half its length. Supraneural bones 3 (Ref. 43141).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01413 (0.00605 - 0.03300), b=3.04 (2.86 - 3.22), in cm total length, based on LWR estimates for this Genus-BS (Ref. 93245).
Trophic level (Ref. 69278):  3.3   ±0.3 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
