Description synthétique Morphologie | Morphométrie

Rayons mous dorsaux (Total): 11; Rayons mous anaux: 24 - 25. Diagnosed from all congeners by the combination of the following characters: elongate dorsal fin (more evident in adult males) with an anterior dark area; concentration of dark pigments on the distal portion of the second through fourth branched anal-fin rays (resulting in a dark dash in this area); presence of a single humeral spot and caudal spot reaching the tip of the middle caudal-fin rays; premaxillary teeth of the outer row bearing only three cusps; three scale rows below the lateral line (Ref. 72397).

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=0.01202 (0.00548 - 0.02637), b=3.08 (2.90 - 3.26), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Niveau trophique (Ref. 69278):  3.0   ±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 (10 of 100).
