Short description
Morfologia | Morfometria
Spine dorsali (totale): 9 - 11; Spine anali 10-14. Body more or less compressed (Ref. 42873, Ref. 42901, Ref. 42907). Body depth 6.5 to 9.5 times in standard length; head length 4.25 to 5.5 times in standard length (Ref. 42907). Upper jaw slightly prominent or of equal length with lower jaw (Ref. 1878, Ref. 42907). Number of dorsal finlets: 9-11 (Ref. 42908, Ref. 51884). Number of branched dorsal and caudal rays: 15 (Ref. 49956). Pectoral fin not reaching dorsal fin origin (Ref. 42873, Ref. 45628). Ganoid scales (Ref. 42904): 57-65 lateral line scales, 44-48 scales around body, 20-26 predorsal scales (Ref. 42908, Ref. 44840, Ref. 44985). Dorsal side olive-green to gray colored, ventral side yellowish; 7 or 8 blackish bars bifurcating on the lower parts of the flanks (Ref. 1878, Ref. 4904, Ref. 44985). Fins are spotted, marbled, or irregularly barred with black (Ref. 4904).
Facultative air-breathing (Ref. 126274)

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5002 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00457 (0.00195 - 0.01073), b=3.05 (2.85 - 3.25), 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
Resilienza (Ref.
120179): Alto, tempo minimo di raddoppiamento della popolazione meno di 15 mesi (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Moderate vulnerability (42 of 100).
