Found on rocky substrates of coastal waters and lower reaches of tropical rivers (Ref. 244). It is uncertain, however, if this species can live in perfectly fresh water for extended periods (Ref. 244). Forms large schools (Ref. 244). Adults feed on small bony fishes, shrimps and cuttlefish (Ref. 244). Viviparous (Ref. 50449). Common by-catch of the inshore demersal gillnet fisheries, particularly those operating off Kalimantan (Ref.58048). Utilized fresh for human consumption; processed into fishmeal and used as bait for other sharks and bony fishes (Ref. 244). Maximum sizes up to 120 cm unconfirmed (Ref. 244).
栖息于沿岸水域与热带河的下游岩石的底部了。 (参考文献 244) 它是不确定的, 然而，是否这一个种能生活于纯淡水长时间.(参考文献 244) 形成大群鱼群。 (参考文献 244) 吃小的硬骨鱼类，虾与墨鱼。 (参考文献 244) 胎生的.(参考文献 50449) 生鲜使用供人类消费; 对于其他的鲨鱼与硬骨鱼类加工成鱼粉与用来当鱼饵了。 (参考文献 244) 最大体长向上到 120 公分未被证实的.(参考文献 244)
Life cycle and mating behavior
成熟度 | 繁殖 | 产卵场 | 卵 | 孕卵数 | 仔鱼
Viviparous, with an unusual columnar placenta (Ref. 244). Maternal and foetal placenta comprises the entire placenta (Ref. 39556). Transplacental nutrient transfer may be hemotrophic (Ref. 39556). Litter size varies from 1 (Ref. 58048) to 14 (Ref. 9997). Size at birth about 13 to 15 cm TL (Ref. 9997). Distinct pairing with embrace (Ref. 205).印度-西太平洋: 索馬利亞 (參考文獻 30573) ，坦尚尼亞，莫三比克 (參考文獻 5213), 巴基斯坦到印尼的爪哇; 然後日本，中國與台灣。 記錄來自澳洲了。 (參考文獻 4959)
