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).
吻是短与圆头的。 它的体盘与它的尾部的上表皮的腰带中央是在不规则的列中粗糙的有大的刺。 上表皮灰色到褐色。 下表面白色的，白灰色，和灰白色或淡色的, 在腹鳍与胸鳍的枝腋上有黑色的区块.(参考文献 6902)
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).
