Épines dorsales (Total) : 28 - 32; Rayons mous dorsaux (Total) : 46 - 58; Rayons mous anaux: 53 - 65; Vertèbres: 71 - 75. A series of 8-10 roundish dark marks along the base of the soft dorsal fin, some or all of which are continuous with vertical bars on the posterior part of the body (Ref. 27732). Predorsal vertebrae usually only 4-5 (6 in a single specimen); rostral tooth plates absent; rim of anterior tubular nostril with 4 nearly equal digitiform processes (or 2 fimbriae and 2 fimbrules); dorsal, anal and caudal fins confluent; caudal fin pointed posteriorly (not truncate or round, typically with 5/5 or 6/6 rays; total caudal fin rays 10-13) (Ref. 39392).

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=0.00282 (0.00130 - 0.00610), b=2.96 (2.78 - 3.14), in cm Total Length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 3.3 ±0.4 se; based on size and trophs of closest relatives

Résilience (Ref. 120179): Haut, temps minimum de doublement de population inférieur à 15 mois (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (13 of 100).
