членистые (мягкие) лучи спинного плавника (общее число) : 53 - 57; членистые (мягкие) лучи анального плавника: 47 - 51; позвонки: 59 - 63. Pores 2-6-7-2; post orbital pore absent, 2 suprabranchial pores, chin pores somewhat drawn together; teeth simple; lower lobe of pectoral fin longer by 1.3-2.4 times that in upper lobe; pocket-like skin fold in front of symphysis of pectoral present; anteanal distance 53%SL, pyriform disk; large gill slit reaching below the base of the lower lobe of the pectoral fin; coloration in pink present in living specimens and peritoneum without black pigmentation (Ref. 41470). Suction disc small, almost equal to diameter of the eye. One nostril on each side of the mouth (Ref. 35388).
On muddy bottoms (Ref. 4702). Maximum depth reported at 1750 m )Ref. 58426). Epibenthic (Ref. 58426). Feeds on benthic and pelagic crustaceans (Ref. 4702) and fishes (Ref. 58426). Female lays about 300 eggs with a diameter of 4.5 mm (Ref. 35388).

Estimates based on models
Preferred temperature (Ref.
123201): 0.4 - 8.6, mean 3 °C (based on 878 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00447 (0.00204 - 0.00980), b=3.17 (2.99 - 3.35), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.8 ±0.58 se; based on food items.
устойчивость к внешним воздействиям (Ref.
120179): высокий, минимальное время удвоения популяции до 15 месяцев (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
