Short description Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 77-86; Anal spines: 0; Anal soft rays: 61 - 71. Eyed side pale brownish, with 3 large, prominent dark ocelli, 1 each above and below pectoral fin, 1 on middle of straight section of lateral line. Head and body with many small, distinct, dark spots and obscure markings along dorsal and ventral body margins. Males with 2 distinct dark markings above upper eye. Dorsal, anal, and pelvic fins on eyed side with indistinct dusky spots and markings. Caudal fin with a pair of marks behind fin base. Pectoral fin on eyed side with broad pale cross bars. Blind side pale. Body deeply ovoid, its depth 1.5 to 1.8 times in SL. Head moderately large, snout shorter than eye, profile deeply notched ahead of interorbital area. Head length3.5 to 4 times in SL. Interorbital region concave, narrow in both sexes. Both eyes on left side of head, front margin of upper eye slightly behind front margin of lower eye. Mouth moderate in size, reaching to or slightly beyond anterior margin of lower eye, length of upper jaw 2.8 to 3.4 times in head length. Teeth in both jaws uniserial. Teeth in upper jaw becoming gradually smaller posteriorly. Teeth of lower jaw about equal in size, similar to anterior teeth of upper jaw. Scales on eyed side ctenoid. Scales on blind side cycloid.

Estimates of some properties based on empirical models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.6250   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01260 (0.00757 - 0.02098), b=2.95 (2.80 - 3.10), based on LWR estimates for species & Subfamily-BS (Ref. 93245).
Trophic Level (Ref. 69278):  3.6   ±0.6 se; Based on diet studies.
Resilience (Ref. 69278):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Low to moderate vulnerability (28 of 100) .
Price category (Ref. 80766):   Very high.
