简单描述检索表 | 型态特徵 | 形态测量图

背棘 (总数) : 0; 臀棘: 0. Adults are rhomboid in shape, young are rounder (Ref. 7251). Short, stiff, bluntly triangular snout; tail shorter than body (Ref. 5578). Upper surface very rough, with solid thornlets scattered all over disc and tail, underside smooth, except for some prickles on snout; a constant pattern of separate orbital thorns, a regular row of 13-17 large thorns from nape to first dorsal fin (Ref. 3167); large, close-set thorns with star-shaped bases at upper disc (Ref. 5578). Coloration highly variable; brownish grey with scattered irregular black blotches dorsally; white ventrally; with darker spots and blotches on tail and pelvic fins; black spot on tip of tail (Ref. 2708).
硬又钝三角形的吻而且尾部短于身体.(参考文献 5578) 体盘菱形的当成鱼时, 较圆的当幼鱼时.(参考文献 7251) 上表皮非常粗糙的, 有坚硬的棘分散的所有体盘之上与尾部, 下面平滑的, 在吻上除了一些刺; 一个个别眼窝的刺不变的样式, 固定的一列 13-17个大的从后颈到第一背鳍的刺;(参考文献 3167) 大的, 靠拢在一起刺在上体盘有星形的基底.(参考文献 5578) 灰褐色的有分散的不规则的黑色斑块背面; 腹侧白色的, 在尾部与腹鳍上有较深色的斑点与斑块; 在尾尖上的黑色的斑点.(参考文献 2708)

Eurybathic, eurythermic (Ref. 4426) and benthic (Ref. 58426). Cold temperate species found in offshore waters (Ref. 88171) on all kinds of bottoms (Ref. 3167), mainly sandy and muddy (Ref. 82311). In the northeast Atlantic most common between 50-100 m depth (Ref. 88187) at temperatures of 2-5 °C (Ref. 89120). Some seasonal migrations have been reported from the western Atlantic (Ref. 52109, 89121). Migration experiments showed that 85 % of tagged individuals remained within 93 km of the release site, with longest distance travelled at 180 km (Ref. 82319). Feed mainly on fish, crustaceans (Ref. 5951) and polychaete worms (Ref. 5578), but also on hydroids, molluscs, cephalopods and echinoderms (Ref. 49751); known to be a scavenger (Ref. 89122). Diet changes with increasing body size (Ref. 82311). Different populations of starry rays mature at different ages and sizes (Ref. 88171). Oviparous (Ref. 3167). Maturity size varies from 44-90 cm TL. Young hatch at ca. 8-12 cm TL (Ref. 114953). Young may tend to follow large objects, such as their mother (Ref. 205). Rarely reaches 60 cm in the North Sea (Ref. 88187). Able to detect weak electric fields generated by potential prey organisms and may also generate its own weak electric fields (Ref. 10311). Probably taken by hake trawlers (Ref. 5578). Few are dried and salted in Iceland (Ref. 6902). It is a common Skate whose landings are converted to fish-meal (Ref. 117245). It has been mentioned that North American specimens grow to a larger size than East-Atlantic specimens (Arve Lynghammar, pers.comm., 11/09).

Life cycle and mating behavior 成熟度 | 繁殖 | 产卵场 | 卵 | 孕卵数 | 仔鱼

Distinct pairing with embrace. Oviparous, laying 10-45 egg cases each year (Ref. 44869, 41305). Eggs are oblong capsules with stiff pointed horns at the corners deposited in sandy or muddy flats (Ref. 205). Egg capsules are 3.4-8.9 cm long and 2.3-6.8 cm wide (Ref. 41250). Paired eggs are laid. Embryos feed solely on yolk (Ref. 50449). In the North Sea, fully formed individuals hatch after 4 months and pups are about 8-11 cm in length (Ref. 44869, 37969). In the Barents Sea, low water temperature may lengthen embryonic development time to 2.5-3 years (Ref. 44869). 東大西洋: 冷岸，格陵蘭與冰島到英倫海峽, 包括北海 (除了南部以外) 與波羅的海西部; 也外海的南非開普敦.(參考文獻 5578) 西大西洋: 在加拿大到美國南卡羅萊那州的格陵蘭與哈得遜灣.(參考文獻 7251)
