Short Description
Snout is short and obtuse. Midbelt of its disc and upper surface of its tail are rough with large thorns in irregular rows. Upper surface ash gray to chocolate brown. Lower surface white, grayish white, pale gray or light fawn color, sooty patches on pelvic fins and axils of pectoral fins [199]. Diet: Barents Sea (data base: of 85 stomachs examined): Round skate fed mainly on bottom benthos, especially Polychaeta (31% by mass) and Gammaridae (14% by mass). Northern shrimp (26% by mass) and fisheries waste (10% by mass) were also major components of their diets. Fish (mostly capelin and young cod) occurred in small quantities. Small individuals (<35 cm TL) consumed exclusively benthos (Polychaeta and Gammaridae) and only those of the 36–40 cm TL-group and larger fed on bigger prey. The largest skates (51–55 cm TL-group) had a high proportion of small benthic organisms (<30–40%). [5910];

Biology
Oviparous, paired eggs are laid. Embryos feed solely on yolk [733]. Distinct pairing with embrace. Young may tend to follow large objects, such as their mother [17086]. Found in deeper shelf and slope waters, in 3-5.5°C water temperature (6902). Benthic (Ref. 58426). Feed on all kinds of bottom animals with preference for invertebrates [7182] like copepods, amphipods and mysids [199]. A nematode, Proleptus mackenzei is a known parasite of the species (Ref. 5951).
