Short description 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 of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.7500   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), based on all LWR estimates for this body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.2   ±0.4 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Low vulnerability (10 of 100) .
