Diagnosis: mouth subterminal and slightly oblique, angle of mouth reaching to below mideye; operculum and predorsal region of head without scales; 29-35 scales in longitudinal series on flanks (plus perhaps 1-2 scales on caudal fin base); 10-14 (mode 11) scales in rearward transverse series; 1st dorsal fin: VI; 2nd dorsal fin: I,10-11 (mode 11): anal fin: I,11-13 (mode 12); pectoral fins: 16-18 (mode 17); caudal fin lanceolate, with 16-17 segmented rays (13-14 of them branched) (Ref. 57403, 79590).
Coloration: Preserved specimens: marbled with brown on back and irregular cross bars on nape; thin dark suborbital bar extending anteroventrally from eye to angle of mouth; several vertical dark lines on cheeks; 5 distinct spots along midlateral line of body, last one located at base of caudal fin; irregular row of tiny spots above midline, scale pockets with dark margins forming reticulate pattern laterally; 1st dorsal fin with 4-5 black longitudinal bands consisting of fine spots; 2nd dorsal fin with approximately 2 bands of fine spots; pectoral and caudal fins with spots forming vertical bands; anal and pelvic fins dusky (Ref. 57403, 79590).
Facultative air-breathing in the genus (Ref. 126274); Inshore marine species; may also be found in brackish waters of lagoons (Ref. 7390, 57403, 79590).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00349 - 0.02862), b=3.09 (2.85 - 3.34), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.3 ±0.5 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).
