Elasmobranchii (Haie und Rochen) (sharks and rays) > Rajiformes (Skates and rays) > Rajidae (Skates)
Etymology: Rajella: Latin, raja, -ae = a sting ray (Raja sp.) (Ref. 45335).
Eponymy: This species is named after the Danish vessel ‘Fylla’ which was used for expeditions to Greenland (1884 & 1886), on one of which the holotype was collected. (Ref. 128868), visit book page.

Kurzbeschreibung Bestimmungsschlüssel | Morphologie | Morphometrie
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 (Ref. 6902).
Body shape (shape guide): other.
Body shape (shape guide): other.
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 (Ref. 3167) like copepods, amphipods and mysids (Ref. 6902). Oviparous. Distinct pairing with embrace. Young may tend to follow large objects, such as their mother (Ref. 205). Eggs are oblong capsules with stiff pointed horns at the corners deposited in sandy or muddy flats (Ref. 205). Egg capsules are 3.8-4.2 cm long and 2.4-2.6 cm wide (Ref. 41303, 41251, 41301). It is captured at low level by-catch in bottom-trawl and longline fisheries (Ref. 117245).

Oviparous, paired eggs are laid. Embryos feed solely on yolk (Ref. 50449). Distinct pairing with embrace. Young may tend to follow large objects, such as their mother (Ref. 205).
