Morphology | Morphometrics
soft rays: 6. This species is distinguished by the following characters: A II,6; dorsal-fin spines are rigid; relatively short snout, its length 12.3-17.2% (mean 15.1%) of SL, and is shorter than postorbital length; posterior margin of the maxilla reaching beyond vertical through middle of pupil; the distance between tips of lateral lacrimal and first suborbital spines is shorter than between tips of first and second suborbital spines; no supplemental preopercular spine; tentacles on supraocular and posterior lacrimal spines are well developed, their lengths greater than orbit diameter; trunk and fins with numerous tentacles; lateral lacrimal and suborbital spines poorly are developed, indistinct, usually tiny spines and often bony protuberances without pointed tips; without the distinct black blotch on soft-rayed portion of dorsal fin (Ref. 106976).

Phylogenetic diversity index (Ref. 82805
= 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
): 3.3 ±0.5 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
): Low vulnerability (15 of 100) .
