Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 77; Anal soft rays: 49; Vertebrae: 58. This species is distinguished from its congeners by the following characters: with antrorse, hook-like projection at the postero-ventral angle of the maxillary; a median spine on frontals above and behind eyes; low number of pectoral fin rays (12); ethmoidal spine is strong; prolonged pectoral peduncle adnate to body; anterior gill arch with 2-3 slightly developed rakers; palatines with a tooth row; short gill filaments on anterior arch, 1-2 times length of developed rakers; vertebrae, precaudal 20, total 58; fin rays, D 77, A 49 and pectoral 12 (Ref. 93007).

Rare species, known from a single specimen (Ref. 34024).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00813 (0.00246 - 0.02688), b=2.92 (2.67 - 3.17), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.3 ±0.5 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).
