Short description Identification keys | Morphology | Morphometrics
Dorsal spines (total): 2; Dorsal soft rays (total): 6 - 8. Without a grooved lateral line. Chin barbel 4-8 % of head length. Suborbital width, 13-15%; postorbital length of head 50-55%. Total gill rakers of first arch (mesial) 11-13; second arch (lateral or mesial) 10-13/10-12. Scale rows below mid-base of first dorsal 25-31; over a distance equal to predorsal length usually 35-42; and between pelvic fin base and gill cover 11-14. Mouth moderately large; lips thick and fleshy (Ref. 13675).
A benthic species found on the continental slope (Ref. 75154).

Estimates based on models
Preferred temperature (Ref. 123201): 5.7 - 9, mean 7.8 °C (based on 107 cells).
Phylogenetic diversity index (Ref. 82804): PD50 = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00214 (0.00109 - 0.00421), b=3.20 (3.03 - 3.37), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278): 3.6 ±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): Moderate vulnerability (38 of 100).
