Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 11 - 13. Body greyish-black to bluish black in color; top of head, gill isthmus and branchiostegal membranes black (Ref. 3974). Deeply pigmented sheath of lateral line. Absence of scales on the top of the head and presence of scales on the opercular bone (Ref. 37108).

Biology     Glossary (e.g. epibenthic)

Found on the lower slope, continental rise and upper abyss, primarily between 4° and 2°C isotherms. Feeds on polychaetes, crustaceans, echinoderms and echiurids. Hovers above or rests on bottom. Long slender pectorals are commonly held erect pointing upward and forward, these may serve a sensory function (Ref. 6727).

Estimates based on models

Preferred temperature (Ref. 123201): 2.3 - 5, mean 3.3 °C (based on 1404 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 1.0000   [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):  3.3   ±0.36 se; based on food items.
Resilience (Ref. 120179):  Low, minimum population doubling time 4.5 - 14 years (Assuming tmax>10).
Fishing Vulnerability (Ref. 59153):  Moderate vulnerability (41 of 100).
Nutrients (Ref. 124155):  Calcium = 12.2 [3.5, 43.0] mg/100g; Iron = 0.426 [0.139, 1.080] mg/100g; Protein = 2.36 [0.00, 6.23] %; Omega3 = 0.308 [0.110, 0.875] g/100g; Selenium = 24.3 [6.7, 82.0] μg/100g; VitaminA = 5.02 [0.95, 23.69] μg/100g; Zinc = 0.317 [0.164, 0.626] mg/100g (wet weight);
