Short description Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 10. Diagnosis: fronto-parietal fontanel absent in adults, sometimes pore-like in juveniles; snout short, more than 3x head lenght; dorsal fin origin just behind pelvic fin insertion; sexual dimorphism affecting anal fin shape; head length/snout length 3.1-4.0; 24-30 lateral line scales; 4.5 scales between lateral line and dorsal fin; 10.5-12 predorsal scales; 12-16 anal fin branched rays; 16-25 gill rakers on lower limb of first gill arch; 8 teeth in outer premaxillary row; adults medium-sized; humeral spot always present; broad black band on flanks; most apparent part of this band reaches or extends beyond vertical through posterior base of dorsal fin (Ref. 80290).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01230 (0.00541 - 0.02797), b=2.99 (2.81 - 3.17), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.1   ±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).
Price category (Ref. 80766):   Unknown.
