Rows of spines along back and sides of tail. Tail rather long. Conspicuous dark rosettes on upper surface of disk in young and adults. Axil of pelvic fin to 1st dorsal fin greater than from axil of pelvic fin to eye (Ref. 7251). Upper surface pale buff or brown freckled with small spots, darker or paler. Lower surface white or pale yellow (Ref. 6902).
沿着背面与尾部的侧边的列棘。 尾部相当长的。 在体盘的上表皮上的显着的黑毛簇当幼鱼与成鱼时。 腹鳍到第一背鳍的叶腋大于从腹鳍到眼睛的叶腋.(参考文献 7251) 上表皮白黄色或有褐色斑点的有小斑点, 比较黑的或较灰白的。 下表面白色或白黄色的.(参考文献 6902)
Occur mostly on outer edge of continental shelf and upper part of continental slope (Ref. 7251). Known salinities at which it has been taken 33.8 off Block Island to 35.3 off Chesapeake bay (Ref. 6902). Feed mostly on decapod crustaceans and to a lesser extent on amphipods, polychaetes, squids and fishes. Oviparous (Ref. 50449). 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 3.7-5.4 cm long and 2.6-3.0 cm wide (Ref. 41301, 41298). Marketed fresh and salted (Ref. 3824).
