Morphology | Morphometrics
soft rays: 5. This species is distinguished by the following characters: A III,5; rigid dorsal-fin spines; snout relatively short, length 13.5-16.9% (mean 15.3%) of SL, shorter than postorbital length; posterior margin of maxilla reaching to or extending beyond vertical through middle of pupil; distance between tips of lateral lacrimal and first suborbital spines shorter than or subequal to that between tips of first and second suborbital spines; with supplemental preopercular spine; poorly developed tentacles on supraocular and posterior lacrimal spines, their lengths usually less than (rarely longer than) orbit diameter; there are a few tentacles on trunk and fins; well-developed lateral lacrimal and suborbital spines, with pointed tips; absence of distinct black blotch on anterodistal part of soft-rayed portion of dorsal fin (Ref. 106976).

= 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01230 (0.00587 - 0.02579), b=3.02 (2.85 - 3.19), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 3.4 ±0.6 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
