Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 8 - 9; Dorsal soft rays (total): 16; Anal spines: 3; Anal soft rays: 11 - 12. Head and body grayish-black dorsally, pale whitish-yellow ventrally. Snout long, strongly pointed (7% of SL). Pectoral filaments 7, the last probably the longest. Upper caudal fin lobe short (34-35% of SL). Swim bladder absent (Ref. 43351).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5039 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00676 (0.00308 - 0.01483), b=3.10 (2.91 - 3.29), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.5 ±0.50 se; based on food items.

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

Fishing Vulnerability (Ref. 59153): Low vulnerability (21 of 100).
