Morphology | Morphometrics
soft rays: 13 - 14;
Vertebrae: 26. This species is distinguished by the following characters: D VI + I,13-14; A I,13-14; caudal fin moderately lanceolate, in adults slightly longer than head length; longitudinal scales 56-60; transverse scales 15-17; body scales are entirely cycloid; scaleless on head except side of nape with 14-18 rows of cycloid scales; color when alive grayish with two dark reddish-brown stripes on head and body; the upper stripe across snout, through mid-eye, ending below middle of soft dorsal fin, while the lower stripe from rear maxilla to middle base of caudal fin with portion on opercle containing a prominent oval dark-brown spot (usually larger than pupil) and stripe ending in a prominent triangular dark brown spot on caudal-fin base; small brown saddles along the back and across predorsal region; small (slightly less than pupil size) ocellus on the upper rays of caudal fin (Ref. 114936).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00708 (0.00332 - 0.01511), b=3.08 (2.90 - 3.26), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 2.9 ±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) .
