(total): 14 - 17;
soft rays: 16 - 20. Very small supraorbital tentacle; in females, first dorsal fin shorter by half than second dorsal fin; in males, about two-thirds; male coloration dark gray with light gray mottling and a thin whitish bar below the eye; oblique suborbital blue streak observed in large males; fins translucent, mottled, and with gray spots; females comparatively pale and anteriorly bearing 2 indistinct, dark double bars that join below lateral line. Dorsal rays III + XI-XIV + 7-10; lateral line interrupted, 14-20 + 15-21; mandibular pores 2-3 + 1-2 + 2-3 (Ref. 54980).

Estimates based on models
Preferred temperature (Ref. 115969
): 25.1 - 29.4, mean 28 °C (based on 553 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00550 (0.00246 - 0.01227), b=3.08 (2.89 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.1 ±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.).
Vulnerability (Ref. 59153
): Low vulnerability (10 of 100) .
