Maturity: Lm ? range ? - ? cm
Max length : 55.0 cm 雄鱼/尚未辨别雌雄; (Ref. 9908)
Occur in the sublittoral zone, 70-90 m on sandy mud bottoms (Ref. 11230). 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 measure 6.1 cm long and 3.7 cm wide (Ref. 41249). Utilization details sketchy (Ref. 9908). Very rarely caught by demersal longline fisheries off Java. Utilized for its meat (Ref.58048).
出现在亚潮带, 在沙泥底上的 70-90 公尺.(参考文献 11230) 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) 卵鞘测量 6.1 公分长与 3.7 公分宽的.(参考文献 41249) 利用细节不完全.(参考文献 9908)

Oviparous (Ref. 9908). 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).中西太平洋: 從上海 (中國) 到古晉 (砂勞越) 的東南中國海 , 與可能外海的印尼東部。 可能地在印度-太平洋廣泛分佈。
