Likely confined to the inner continental shelf (Ref. 9840), over sandy and mud bottoms (Ref. 30573). Recorded from coastal waters and river mouths (Ref. 45255). Feeds on bottom crustaceans including shrimp, crabs and small lobsters (Ref. 5578). Ovoviviparous (Ref. 50449). Important food fish, the skin and flesh are dried or used to produce leather for purses and bags (Ref. 9840). Caught in very large quantities in the demersal tangle net, bottom trawl and trammel net fisheries. Utilized for its meat, skin (high value) and cartilage (Ref. 58048). It is parasitised on the dorsal skin surface by the monogeneans Dendromonocotyle citrosa, D. colorni, D. ukuthena (Ref. 124058) and D. lotteri (Ref. 124051).
或许局限于大陆架内侧 (参考文献 9840)了, 在沙泥底之上。 (参考文献 30573) 记录自沿岸水域与河口了。 (参考文献 45255) 吃底部甲壳动物包括虾，螃蟹与小的龙虾。 (参考文献 5578) 卵胎生的.(参考文献 50449) 重要的食用鱼, 皮肤与肉被乾制或用来生产皮革做成钱包与袋子。 (参考文献 9840)
Life cycle and mating behavior
成熟度 | 繁殖 | 产卵场 | 卵 | 孕卵数 | 仔鱼
Exhibit ovoviparity (aplacental viviparity), with embryos feeding initially on yolk, then receiving additional nourishment from the mother by indirect absorption of uterine fluid enriched with mucus, fat or protein through specialised structures (Ref. 50449). Distinct pairing with embrace (Ref. 205). Bears 2 young in summer (Ref. 5578). Gives birth to litters of 1-4 pups; born at 18-21 cm WD (Ref.58048).印度-太平洋: 印度到新幾內亞,北至日本。 記錄來自紅海與東非海岸了，但是這些西方的記錄需要被確認。 採集自恒河的河口與淡水水域了。 (參考文獻 33178) 可能一個複合種.(參考文獻 35766)
