Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 7; Anal spines: 0; Anal soft rays: 8 - 11. Diagnosis: caudal peduncle long and moderately compressed, narrowest at base of caudal fin (Ref. 57128). Caudal-peduncle length comprised 4.5-5.2 times in standard length, its depth comprised 2.5-4 times in its length (Ref. 57128, 81646). Distance from head to dorsal fin 0.7-1.0 times the head length; posterior nostrils at same distance from eyes than anterior nostrils from snout tip (Ref. 57128).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5020 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.1 ±0.4 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
