Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 3; Dorsal soft rays (total): 12 - 13; Anal spines: 1; Anal soft rays: 9; Vertebrae: 27 - 29. This species is distinguished by the following characters: spined posterior and lower margins of the praeoperculum with an unspined notch in the angular part of it; insertion of ventral fins at the level of the vertical of the posterior margin of the pectoral fin insertion; upper jaw extends beyond the vertical of posterior eye margin; soft rays 12-13 in dorsal fin, 9-10 in anal fin; first branchial arch with 27-30 rakers; vertebrae 27-29; pyloric caeca 7 (Ref. 83719).

This was caught by non-closing fishing gear in water horizons of 1000-0 to 2000-0 m (Ref. 83719).

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=0.01096 (0.00451 - 0.02668), b=3.10 (2.89 - 3.31), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.4 ±0.3 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.).

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