Short description
Identification keys | Morphology | Morphometrics
Dorsal soft rays (total): 8 - 10. Single infracaudal organ, and the cleithral symphysis with a forward-directed spine. A small GO1 present. No lateral line canal on posttemporal bone. Dorsal origin ahead of that of anal by about a fourth of its length. Mouth large, posterior margin of maxillary behind eye. Maxillary slightly shallower than posterior supramaxillary and strongly convex ventrally. Supramaxillaries exposed, not covered by infraorbitals. A row of 8-10 teeth on external lateral face of dentary. A small supraorbital bone present. Pectoral base and adjacent area without scales.

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00407 (0.00154 - 0.01080), b=3.17 (2.95 - 3.39), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.3 ±0.5 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.
