Morphology | Morphometrics
soft rays: 31 - 33;
Vertebrae: 53 - 55. Dorsal surface of the body dark; 8-11 irregular (often anteriorly pointed V-shaped) black blotches or bands on upper half of the body; a white-rimmed black ocellus on caudal peduncle; sparse white spots on body and dorsal and caudal fins. Hyomandibular process with the mid- to lower lateral edge mesially protruded. One to 2 small to medium-sized scales found on the undersurface of each side of the lower jaw. Pelvic fin absent. Cheek scales 9-13 (Ref. 43157).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01122 (0.00514 - 0.02450), b=3.04 (2.87 - 3.21), in cm Total Length, based on all LWR estimates for this body shape (Ref. 93245
Trophic Level (Ref. 69278
): 3.8 ±0.7 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 (24 of 100) .
