Espinhos dorsais (total) : 0; Espinhos anais: 0. Bronze above, fading to grayish brown after death and in preserved specimens; light below, without conspicuous markings on fins; no conspicuous white band on flanks (Ref. 9997).
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).
