Length at first maturity / Size / Weight / Age
Maturity: Lm 94.5, range 89 - 100 cm
Max length : 135 cm TL male/unsexed; (Ref. 6871)
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).
Viviparous, placental (Ref. 50449). Females give birth to 1-7 pups every year between February and May (Ref. 6871). Size at birth about 50 cm (Ref. 6871). Distinct pairing with embrace (Ref. 205).
