Short description
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 3; Raggi dorsali molli (totale) : 13; Spine anali: 1; Raggi anali molli: 9 - 10; Vertebre: 27 - 28. The species is distinguished by the following characters: spined posterior and lower margins of the praeoperculum, in the angular part of it is an unspined notch; insertion of the ventral fins is in front of the vertical of the posterior margin of the pectoral fin insertion; upper jaw extends beyond the vertical of the posterior eye margin; soft rays in dorsal fin 13, in anal fin 9-10; first branchial arch with 31-33 rakers; vertebrae 27-28; pyloric caeca 8 (Ref. 83719).
Specimens were seined with non-closing fishing gear in the range of depths 3000-0 m and with bottom fishing gear is seined at 1640-2000 m (Ref. 83719).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 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
Resilienza (Ref.
120179): Molto basso, tempo minimo di raddoppiamento della popolazione più di 14 anni (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
