Short description Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 74-85; Anal soft rays: 61 - 71; Vertebrae: 60 - 63. Head rounded in dorsal outline; snout broadly rounded; eyes small and laterally placed. Postorbital margin not entirely covered with bone. Frontal fontanelle long and narrow; occipital fontanelle long and oval-shaped. Supra-orbital and `dermosphenotic' bones separated. Tooth plates relatively broad. Pectoral spine straight; outer side with small downward serrations over entire length. Gill rakers relatively long and distantly set. Suprabranchial organ well developed. Openings of secondary sensory canals show a regular pattern.

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00724 (0.00336 - 0.01560), b=2.99 (2.82 - 3.16), based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.4   ±0.5 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 (21 of 100) .
Price category (Ref. 80766):   Unknown.
