Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 62.0 cm TL male/unsexed; (Ref. 35909)
Dorsal spines (total): 2. Snout moderately pointed, 1.4-1.6 times orbit diameter; anterolateral margin incompletely supported by bone; upper jaw slightly less than 1/3 HL; orbit 1.5-1.8 into postorbital length; subopercle produced into slender point ventrally, the tip protruding slightly beyond angle of preopercle. Color overall dark chocolate brown. Nasal fossa with small scales on anteroventral corner but otherwise naked. Spinules on body scales below dorsal interspace imbricate, broadly trihedral, with wide lateral buttresses, in 3-5 saw-toothed, divergent rows. Anus immediately anterior to anal fin; no external sign of light organ.
A benthic species found on the continental slope (Ref. 75154).

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=0.00251 (0.00128 - 0.00492), b=3.19 (3.03 - 3.35), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.6 ±0.5 se; based on size and trophs of closest relatives
Resilience (Ref.
120179): Very Low, minimum population doubling time more than 14 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Moderate vulnerability (45 of 100).
