Short description Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 45-48; Anal spines: 0; Anal soft rays: 32 - 35.

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.6250   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00741 (0.00398 - 0.01382), b=3.01 (2.85 - 3.17), based on LWR estimates for this species & Family-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.7   ±0.6 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 (16 of 100) .
Price category (Ref. 80766):   Unknown.
