生态学
海洋 居于水底的; 深度上下限 10 - 800 m (Ref. 106604). 溫帶; 67°N - 27°N, 25°W - 37°E
Eastern Atlantic (Iceland, southern Norway, Skagerrak and Morocco) and the Mediterranean Sea.
Records as far south to Mauritania and Senegal could not be verified due to lacking descriptions and specimens; most are probably misidentifications of Leucoraja leucosticta.

Found in offshore shelf waters and on upper slope, mainly around the 100 m line (Ref. 3167). Depth range from 70-275 m (Ref. 03167), and from 463-676 m in eastern Ionian Sea (Ref. 56504). Feed on all kinds of bottom animals (Ref. 3167). Oviparous. Distinct pairing with embrace. Young may tend to follow large objects, such as their mother (Ref. 205).
