Short description Identification keys | Morphology | Morphometrics

Insertion of the pelvic fins well in advance of the origin of the dorsal fin. Separation of palatine tooth patches on the midline and disc-like lateral line plaques (Ref. 37108). Light colored, the lower part of the head and the gill cover black, abdominal region blackish. Lining of mouth is dark (Ref. 37108).

Inhabits the abyssal depths (Ref. 4448).

Estimates based on models

Preferred temperature (Ref. 123201): 2.4 - 4.2, mean 2.7 °C (based on 276 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00087 (0.00033 - 0.00229), b=3.07 (2.84 - 3.30), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.5 ±0.50 se; based on food items.

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (40 of 100).
