Short description
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 9 - 12; Raggi dorsali molli (totale) : 11 - 12; Spine anali: 1; Raggi anali molli: 10 - 12. This species is characterized by the following: first dorsal fin pattern and coloration variable between individuals, typically, first dorsal fin rounded, moderate height, white margin, and one brown or black stripe inframarginally; the first spine of first dorsal fin always longest, rarely elongated; rounded to elliptical red-orange spots present ventral to inframarginal stripe, turning black in preservative; the second dorsal fin with yellow-orange margin and one black band inframarginally, rounded red-orange spots present on membrane between elements at base, turning black in preservative; live color with caudal and pectoral fins red-orange; prominent pelvic frenum, inner rays fused for less than half their length; ventero-posterior branchiostegal membrane dusky; D1 modally X; D2 modally I,12; A I,11; caudal fin modally 14 segmented rays; 48-60 lateral scales; 17-22 predorsal scales (Ref. 83659).
Facultative air-breathing (Ref. 126274)

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=0.01023 (0.00595 - 0.01759), b=2.90 (2.75 - 3.05), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.2 ±0.4 se; based on size and trophs of closest relatives
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
