Elasmobranchii (haaien en roggen) (sharks and rays) > Rajiformes (Skates and rays) > Rajidae (Skates)
Etymology: Amblyraja: Greek, amblys = darkness + Latin, raja, -ae = ray (Raja sp.) (Ref. 45335).
Eponymy: Thomas Frerichs was captain of the research vessel ‘Walther Herwig’ from which the holotype was collected. He was honoured for: “…his keen interest in deepsea catches, which assured us many precious discoveries”. (Ref. 128868), visit book page.

Issue
Possibly a junior synonym of A. hyperborea due to strong morphological similarity according to Ebert & Stehmann (2013, Ref. 98315) and Weigmann (2016, Ref. 118749) (Ref. 118749).
Environment: milieu / climate zone / depth range / distribution range Ecologie
marien bathydemersaal; diepte 600 - 2610 m (Ref. 114953). Deep-water; 30°S - 50°S, 78°W - 51°W (Ref. 114953)
Verspreiding Landen | FAO regio's | Ecosystemen | Voorkomen | Point map | Introducties | Faunafri
Southwest Atlantic: off the mouth of Río de la Plata, Argentina (Ref. 26282, Ref. 114953) and Uruguay (Ref. 58839, Ref. 114953). Possibly Southeast Pacific: Chile (Ref. 27540, Ref. 114953).
Grootte / Gewicht / Leeftijd
Found on continental slope and upper abyssal plain. Feeds on small benthic invertebrates, adults possibly piscivorous (Ref. 114953). Oviparous (Ref. 50449). Males reaches maturity by ca. 76 cm TL; young hatch at ca. 22 cm TL (Ref. 114953). Produces horny-shelled eggs (Ref. 205).
Levenscyclus en paargedrag Maturiteit | Voortplanting | Paaien | Eieren | Fecunditeit | Larven
Oviparous, paired eggs are laid. Embryos feed solely on yolk (Ref. 50449). Eggs have horn-like projections on the shell (Ref. 205).

Estimates based on models
Fylogenetische diversiteitsindex (Ref. 82804): PD50 = 0.5010 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00302 (0.00141 - 0.00645), b=3.24 (3.07 - 3.41), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trofisch niveau (Ref. 69278): 4.2 ±0.3 se; based on size and trophs of closest relatives
Weerstandsvermogen (Ref. 120179): laag, minimale populatieverdubbelingstijd 4,5-14 jaar (Fec assumed to be <100).
Fishing Vulnerability (Ref. 59153): High vulnerability (56 of 100).
Nutrients (Ref. 124155): Calcium = 7.32 [1.45, 37.52] mg/100g; Iron = 0.36 [0.08, 1.12] mg/100g; Protein = 16.7 [13.9, 19.2] %; Omega3 = 0.644 [0.204, 2.385] g/100g; Selenium = 16.5 [4.4, 50.5] μg/100g; VitaminA = 11.9 [2.8, 51.8] μg/100g; Zinc = 0.256 [0.125, 0.482] mg/100g (wet weight);
