Short description Morphology | Morphometrics

Dorsal spines (total): 7; Dorsal soft rays (total): 10-11; Anal spines: 1; Anal soft rays: 10. Distinguished by the following characters: body colour light brown; two oblique dark bands originating on head below eye, the upper degenerating into diffuse purplish brown blotches from the pectoral to caudal peduncle; black stripe arising at the pectoral insertion and running along lower body before breaking into small black spots above anal fin; dorsal fins with a horizontal dark band near the base; dark blue mark on membrane distally between first and second rays of D2; iridescent irregular blue blotches along flanks; three or more approximately vertical bands on upper caudal; vertebrae 10+15 (vertebral counts taken from radiograph); body cylindrical; snout blunt; eyes large, and close together dorsally; origin of pectorals under posterior margin of operculum; caudal oval and elongate; 7th pectoral ray extended into a filament; pelvics united into cup-shaped disc with branched rays; origin of pelvics covered by a loose sheath of skin; scales cycloid on belly and dorsally to second dorsal origin; posterior lateral scales peripheral ctenoid; head and predorsal region naked (Ref. 45534).

Biology     Glossary (e.g. epibenthic)

Facultative air-breathing (Ref. 126274); Found in muddy coastal areas to upper estuaries, rocky reefs, in sea grass beds and mangroves (Ref. 9002).

Estimates based on models

Preferred temperature (Ref. 123201): 14.6 - 24.9, mean 17.9 °C (based on 272 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.6250   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00708 (0.00333 - 0.01504), b=3.09 (2.92 - 3.26), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.3   ±0.4 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).
