Description synthétique Clés d'identification | Morphologie | Morphométrie

Rayons mous dorsaux (Total) : 270. Dark purplish grey in color (Ref. 3973). Anal rays about 270 (Ref. 3973).

Found on the continental slope near the upper limit of abyssal zone (Ref. 6726). Epibenthic (Ref. 58426). Probably most common in 800 to 2,000 m (Ref. 5235). Do not tolerate higher water temperatures (Ref. 5951). Feeds mainly on Decapoda, Natantia, amphipods, but also fishes and cephalopods (Ref. 6726). Caught by bottom longline and baited fish trap (Ref. 85806).

Estimates based on models

Preferred temperature (Ref. 123201): 0.4 - 9.1, mean 3.4 °C (based on 3305 cells).

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

Bayesian length-weight: a=0.00059 (0.00030 - 0.00117), b=3.14 (2.96 - 3.32), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Niveau trophique (Ref. 69278): 4.1 ±0.4 se; based on diet studies.

Résilience (Ref. 120179): Milieu, temps minimum de doublement de population : 1,4 à 4,4 années (Assuming fecundity > 100).

Fishing Vulnerability (Ref. 59153): High vulnerability (60 of 100).

Nutrients (Ref. 124155): Calcium = 16.7 [9.7, 37.5] mg/100g; Iron = 0.412 [0.206, 0.836] mg/100g; Protein = 17.4 [15.1, 19.8] %; Omega3 = 0.376 [0.157, 1.018] g/100g; Selenium = 36.5 [15.4, 82.9] μg/100g; VitaminA = 9.95 [1.98, 51.99] μg/100g; Zinc = 0.27 [0.17, 0.41] mg/100g (wet weight);
