Short description Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 8-10; Anal spines: 0; Anal soft rays: 5 - 8. A series of large gray and nearly circular large spots latero-dorsally on body, some of which may be nearly fused to form long marks; a series of nearly circular large spots laterally on flank, some may be fused to form long marks, slightly smaller than the latero-dorsal circular large spots; these two series of large spots may be aligned one under the other or alternate one another; scattered, irregularly shaped and slightly smaller spots ventro-laterally on body; a series of mid-dorsal large spots on body, absent in large specimens; pelvic fin origin equidistant from base of middle caudal fin rays and a vertical between posterior margin of opercle (in juveniles, about 2.4 cm TL) and the posterior margin of pectoral fin or even slightly backward (in specimens about 8.3 cm TL); distance from dorsal fin origin to base of middle caudal fin rays 1.7-1.9 in predorsal distance and absence of spots on opercular region in intermediate and large size specimens; anus under anterior part of dorsal fin base (Ref. 52473).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00851 (0.00355 - 0.02043), b=2.93 (2.74 - 3.12), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.2   ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  Low, minimum population doubling time 4.5 - 14 years (Assuming Fec < 100).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
