A little-known shark found inshore and offshore on the continental shelves from the intertidal to at least 40 m depth (Ref. 9997). Feeds mainly on teleost fishes, also crustaceans (Ref. 6871). Viviparous (Ref. 50449). Utilized for human consumption (Ref. 244, 9997) and probably for the oriental shark fin trade (Ref. 244).
