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).
北美洲中大的魟魚.(參考文獻 2850) 捕食甲殼動物和魚類。 (參考文獻 6885) 卵生的。 明顯的成對出現。 幼魚可能傾向跟隨大的個體, 例如他們的母親.(參考文獻 205) 卵為長方形鞘囊具有僵硬的觸角沈積在沙灘或泥灘的角落.(參考文獻 205) 卵鞘是 22.8-30.5 公分長與 11.0-19.4 公分寬的.(參考文獻 41249,41300,41357) 胸鰭供人類消費使用了。 (參考文獻 2850) 在市場上銷售生鮮和冷凍; 油炸後食用與燒烤.(參考文獻 9988)
