Largest skate in North America (Ref. 2850). Feed on crustaceans and fishes (Ref. 6885). Oviparous. Distinct pairing with embrace. Young may tend to follow large objects, such as their mother (Ref. 205). Young hatch at 18-23 cm TL (Ref. 114953). Eggs are oblong capsules with stiff pointed horns at the corners deposited in sandy or muddy flats (Ref. 205). Egg capsules are 22.8-30.5 cm long and 11.0-19.4 cm wide (Ref. 41249, 41300, 41357). Pectoral fins utilized for human consumption (Ref. 2850). Marketed fresh and frozen; eaten fried and baked (Ref. 9988).
北美洲中大的 鱼.(参考文献 2850) 捕食甲壳动物和鱼类。 (参考文献 6885) 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 22.8-30.5 公分长与 11.0-19.4 公分宽的.(参考文献 41249,41300,41357) 胸鳍供人类消费使用了。 (参考文献 2850) 在市场上销售生鲜和冷冻; 油炸后食用与烧烤.(参考文献 9988)

Up to 7 embryos per egg case (Ref. 2850). Oviparous, paired eggs are laid. Embryos feed solely on yolk (Ref. 50449). Distinct pairing with embrace. Young may tend to follow large objects, such as their mother (Ref. 205).北太平洋: Glubokaya 海灣， Navarin 海岬與僵局岸堤到塞德羅斯島，墨西哥的下加利福尼亞。
