Dorsale stekels (totaal) : 3; Dorsale zachte stralen (totaal) : 12 - 13; Anale stekels: 1; Anale zachte stralen: 8 - 10; Wervels: 27 - 28. The species is distinguished by the following: spined posterior and lower margins of the praeoperculum, and in the angular part of the praeoperculum, an unspined notch; insertion of the ventral fins is slightly in front or at the level of the vertical of the posterior margin of the pectoral fin insertion; upper jaw extends to the vertical of the posterior eye margin; soft rays in the dorsal fin 12-13, in anal fin 8-10; first branchial arch with 28-32 rakers; vertebrae 27-28; pyloric caeca 7-8 (Ref. 83719).
Specimens were seined using non-closing fishing gear, the largest depths of capture were 1650-0 m, and the smallest depths were 50-900 m (Ref. 83719).

Estimates based on models
Fylogenetische diversiteitsindex (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).
Trofisch niveau (Ref.
69278): 3.4 ±0.3 se; based on size and trophs of closest relatives
Weerstandsvermogen (Ref.
120179): Zeer laag, minimale populatieverdubbelingstijd meer dan 14 jaar (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
