Maturity: Lm ?  range ? - ? cm
Max length : 38.0 cm SL male/unsexed; (Ref. 3590)
Benthic at 692-1420 m (Ref. 58302). Adults bathybenthic on continental slope and rise at temperatures generally warmer than 4°C while larvae are pelagic near the surface. Feeds on mysids and decapods. Synchronously hermaphroditic (Ref. 3590). Minimum depth from Ref. 58018.

Estimates based on models
Preferred temperature (Ref. 123201
): 5.9 - 16.3, mean 10.5 °C (based on 458 cells).
Phylogenetic diversity index (Ref. 82804
= 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00490 (0.00195 - 0.01230), b=3.03 (2.81 - 3.25), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.3 ±0.45 se; based on food items.
Resilience (Ref. 120179
): Very Low, minimum population doubling time more than 14 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153
): Moderate vulnerability (36 of 100).
