简单描述

A distinctive skate with bright yellow spots, often in rosettes and whorls and sometimes forming eye-like markings on pectoral bases (Ref. 5578). Snout short, broad and blunt, disc narrow, and tail longer than body; disc very rough with 2-4 rows of thorns from midback to 1st dorsal fin, and with broadly rounded corners (Ref. 5578). Yellowish brown above, white below; some grey-brown above with white spots (Ref. 5578).
Body shape (shape guide): other.
一个特殊的 鱼有鲜黄色的斑点, 经常丛集成螺纹状与有时在胸鳍基底上形成眼状的斑纹.(参考文献 5578) 吻短的,宽的与钝的, 体盘狭窄的, 与尾部较长超过身体; 体盘非常粗糙的有来自背部中央到第一背鳍的 2-4 列的刺, 而且有宽圆形的角落。 (参考文献 5578) 背面土黄色, 腹面白色的; 一些背面灰褐色的有白色的斑点.(参考文献 5578)
Found in offshore areas on soft bottoms (Ref. 5578). Feed on bony fish and benthic invertebrates (Ref. 5578). 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 7.3 cm long and 4.2 cm wide (Ref. 41249). Caught by hake trawlers (Ref. 5578).
在软质底部上发现于外海区域了。 (参考文献 5578) 捕食硬骨鱼与底栖的无脊椎动物。 (参考文献 5578) 卵生的。 明显的成对出现。 幼鱼可能倾向跟随大的个体, 例如他们的母亲.(参考文献 205) 卵为长方形鞘囊具有僵硬的触角沈积在沙滩或泥滩的角落.(参考文献 205) 卵鞘是 7.3 公分长与 4.2 公分宽的.(参考文献 41249) 被鳕鱼底拖网捕获了。 (参考文献 5578)
