Northeastern Atlantic: Iceland to the British isles; it was formerly more widespread, including the Mediterranean Sea and North Africa, but the range is thought to be reduced due to fishing.

背棘 (总数) : 0; 臀棘: 0. This species is characterized by the following: snout broadly angular, length 5-6.3 times orbit length; disc broadly rhombic, anterior margin deeply concave; a row of 12-31 predorsal thorns in median row along tail (disc smooth in young; denticles confined to dorsal head and along anterior disc margin on both surfaces in adults; disc thorns small in young, largely absent in adults); lateral thorns on tail perpendicular to body axis; interspace between dorsal fins 1.2 ± 0.4 TL, the fins rounded, upright, near tail tip; upper surface olive-grey or brown with a variable pattern of light blotches, with yellowish ring-like markings; underside greyish; iris yellowish (Ref. 114953, 127223).
吻非常长而尖的; 眼睛前的长度 2,5-4,0 倍距离他们之间; 体盘宽广菱形具有尖锐的外角; 上表皮与下面平滑的当幼鱼时, 部分多刺在较大的标本中; 没有在体盘上的刺 , 一列 12-18个刺沿着尾部; 40-56个齿列; 上表皮橄榄灰色或褐色的有灰色的一个淡色的斑点可变图案，下面到蓝灰色.(参考文献 3167)

Benthic species in shelf and slope waters, mainly within the 200 m range along the continental shelf, but down to 600 m along continental slopes and seamounts (Ref. 127222). Feeds on all kinds of bottom invertebrates and fish, including other skates (Ref. 114953). Oviparous, with long embryonic development. Males reach maturity at ca. 115 cm TL, females at 123 cm TL; birth size at ca. 21 cm TL (Ref. 114953). Biology may be unclear due to past taxonomic confusion Distinct pairing with embrace. Young may tend to follow large objects, such as their mother (Ref. 205). Mate in spring and the egg capsules are laid during the summer. Eggs are oblong capsules with stiff pointed horns at the corners deposited in sandy or muddy flats (Ref. 205). Egg capsules are 10.6-24.5 cm long and 5.0-14.5 cm wide (Ref. 41250). About 40 eggs per individual are laid annually (Ref. 41250). Flesh is marketed fresh or smoked (Ref. 35388).

Oviparous, paired eggs are laid. Embryos feed solely on yolk (Ref. 50449). Egg-cases laid in spring and summer, very large (Ref. 3167). Distinct pairing with embrace. Young may tend to follow large objects, such as their mother (Ref. 205). Eggs have horn-like projections on the shell (Ref. 205).東大西洋: 挪威，冰島，法羅到塞內加爾, 包括地中海西部與波羅的海西部。 從許多的它的從前的分佈區域因為使用拖網而滅絕了。 (參考文獻 27438)
