Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 9 - 12; Anal spines: 0; Anal soft rays: 10 - 12. Presence of a small dark ocellus at the rear part of the dorsal fin, even visible in subadults; dark cross bars 13-19; absence of cross bars on caudal fin; a narrow black margin on the dorsal fin; females almost without spots on the sides; 75 diagnostic molecular synapomorphic characters in the mitochondrial gene regions investigated (Ref. 52509). Remarks: Scales on mid-longitudinal series 25-28 + 2-3 on caudal fin base (Ref. 52509).

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=0.01047 (0.00692 - 0.01585), b=3.24 (3.12 - 3.36), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 2.9 ±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).
