Short description Identification keys | Morphology | Morphometrics
Dorsal soft rays (total): 9. Diagnosis. This species is distinguished by the following set of characters: 9 dorsal-fin soft rays; fourth fin spine longest; 17 pectoral-fin rays; 39-44 longitudinal scales rows; 23 pored lateral-line scales; lateral surface of trunk covered with ctenoid scales; anteroventral surface of body and pectoral-fin base covered with exposed cycloid scales; lateral surface of maxilla with no longitudinal ridge; no spines on lateral surface of lacrimal; posterior margin of anterior lacrimal spine with 1–3 small spines; simple posterior lacrimal spine directed ventroposteriorly; no median interorbital ridge and no coronal spine; with occipital pit and supplement preopercular spine; relatively short fin spines and rays, longest pectoral-fin ray (31.5-33.5% of SL); the space between the upper and lower opercular spines is not covered by skin with sensory pores and canals; length of supraocular tentacle is less than or approximately equal to pupil diameter; no tentacles on lateral surface of trunk, except on pored lateral-line scales (Ref. 75652).

Estimates based on models
Preferred temperature (Ref. 123201): 17.5 - 24.2, mean 19.9 °C (based on 20 cells).
Phylogenetic diversity index (Ref. 82804): PD50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01318 (0.00635 - 0.02739), b=3.02 (2.85 - 3.19), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278): 3.5 ±0.2 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).
