Dorsal spines (total): 2. The snout moderate in adults to long in young, sharply pointed, 38-50% of head length (HL), anterolateral margin completely supported by bone Orbit diameter less than postorbital length of head, 24-30% HL, 1.3 - 2.1 times into snout length. The upper jaw extending posteriorly to below hind margin of pupil. Short, narrow, pointed flap of subopercle. Short, naked black fossa of light organ anterior to anus, with the anus removed from anal fin by one or two scale rows. Underside of head with small, finely spinulated scales except along the border of the mouth, ventral and posterior margins of preopercle, and anteriorly on lower jaw. Scattered scales on nasal fossa, mostly confined ventrally. Body scales with short overlapping spinules in 4-7 divergent rows, none especially broad-based nor enlarged. Fins without prominent markings (Ref. 35909).
Found on the continental slope. Benthic (Ref. 75154).

Estimates based on models
Preferred temperature (Ref.
123201): 6.8 - 10.6, mean 8.3 °C (based on 6 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00102 (0.00046 - 0.00225), b=3.06 (2.88 - 3.24), in cm total length, based on all LWR estimates for this body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.5 ±0.5 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 to moderate vulnerability (27 of 100).
