Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 2; Dorsal soft rays (total): 7; Anal soft rays: 4. This species is distinguished from its congeners by the following set of characters: bicuspid teeth with elliptic medial cusp and angle between dentaries usually larger than 80°; roundish dark spots on head and flanks; extremely small dark spots on head and anterior portion of trunk-more than 13 dark spots on the first plate in the dorsal series in specimens up to 82 mm SL; moderate or blunt keels on lateral series of plates; short to moderate dorsal fin, far from reaching adipose plate; anterior portion of trunk with similar color pattern to posterior portion in adults; caudal peduncle (8.1-9.8 % SL); two parallel spot rows per inter-radial membranes in dorsal fin; spots diameter that increase in size posteriorly to head; beige brown background coloration of dorsal fin, similar to the main body background in live specimens; and deep head (18.2-20.7 % SL) (Ref. 138215).
Body shape (shape guide): elongated; Cross section: oval.

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01585 (0.00726 - 0.03460), b=2.95 (2.78 - 3.12), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
Resilience (Ref.
120179): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (11 of 100).
