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).
棲息於沿岸水域與熱帶河的下游岩石的底部了。 (參考文獻 244) 它是不確定的, 然而，是否這一個種能生活於純淡水長時間.(參考文獻 244) 形成大群魚群。 (參考文獻 244) 吃小的硬骨魚類，蝦與墨魚。 (參考文獻 244) 胎生的.(參考文獻 50449) 生鮮使用供人類消費; 對於其他的鯊魚與硬骨魚類加工成魚粉與用來當魚餌了。 (參考文獻 244) 最大體長向上到 120 公分未被證實的.(參考文獻 244)
Life cycle and mating behavior

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)
