Two-spotted first dorsal fin; chin uniformly pigmented; dossal saddles moderate to wide; incomplete lateral line; preopercular spines slight to moderate, palatine teeth weak to moderate, and postpectoral prickling slight to moderate.

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=0.00794 (0.00389 - 0.01621), b=3.12 (2.95 - 3.29), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.2 ±0.4 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.
