A coastal species, which enters coastal lagoons, shallow bays and estuaries (Ref. 81259). Found over sandy and muddy bottoms, sometimes near rocky reefs (Ref. 12951). Feeds on bottom fishes, crustaceans and mollusks. Ovoviviparous, gestation period about 4 months and 4-7 young are produced. Wings marketed smoked, dried-salted, and also used for fishmeal and oil. Harmful to shellfish banks; dangerous to bathers and fishers due to its poisonous spine. Barbed poison spine is a modified denticle that can be 35cm long, shed occasionally and replaced (Ref. 35388). Maximum reported width about 150 cm (Ref. 81259).
发现在沙泥底上了, 有时在河口与邻近岩礁中.(参考文献 12951) 吃底栖无脊椎动物与鱼类。 卵胎生的, 妊娠时期大约 4个月与 4-7个幼鱼生产。 翼在市场上销售烟熏, 乾燥盐腌 , 以及制成鱼浆与油。 对贝浅堆有害; 对游泳者有危险,而且渔夫由于它的有毒棘。 吃底层鱼类,甲壳动物与软件动物。 有刺的毒棘是一个进化修改后的细齿能成为 35 公分长, 偶然地脱落而且取代了.(参考文献 35388)
