Short description Morphology | Morphometrics

Dorsal spines (total): 7; Dorsal soft rays (total): 8-9; Anal spines: 1; Anal soft rays: 10. Distinguished by the following characters: predorsal midline with 10-14 cycloid scales; belly with cycloid scales close to anus; lateral scales 31-36 reaching upper pectoral base; transverse series back 8-9; transverse series forward 9-12; upper jaw with 33-38 tricuspid teeth; modally 35-36; head and body ventrally dusky in males, mostly immaculate in females; pelvic disk dusky in males with dusky blotches medially; females pelvic disk generally without pigmentation (Ref. 46975).

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=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), based on all LWR estimates for this body shape (Ref. 93245).
Resilience (Ref. 69278):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Low vulnerability (14 of 100) .
