A dwarf softnose skate with a bluntly pointed snout and very large close-set eyes; tail longer than body in adult; pectoral disc angular with rounded corners, and anterior edges more undulated in adult male than in female; large thorns around eyes, on shoulders, and in interrupted single row from back to dorsal fins (Ref. 5578). Brownish-grey above, with 6-7 crossbars on tail; underside pale with dark brown areas along the front and rear edges of disc, on snout and on underside of tail (Ref. 5578).
Body shape (shape guide): other.
一个矮小的软鼻 鱼具有一个顿尖的吻与非常大的靠拢在一起眼; 尾部较长超过身体在成鱼中; 胸盘有角的与圆角 , 与前缘在雄性成鱼中较波浪状超过母鱼; 眼的周围大刺, 在肩上, 而且形成中断的一列从背部到背鳍.(参考文献 5578) 背面灰褐色的, 在尾部上有 6-7 交叉的条纹; 下面灰白的有深褐色的在吻与尾巴下上,区域沿着体盘的前面与后缘.(参考文献 5578)
Found on the upper slope (Ref. 5578). Oviparous (Ref. 50449). Eggs have horn-like projections on the shell (Ref. 205). Probably taken by hake trawlers (Ref. 5578).
