Grey or grey-brown on dorsal surface, white or cream below, with a conspicuous band of white on sides from pelvic fins to first dorsal fin; pectoral, dorsal and pelvic fins, and ventral lobe of caudal fin black or dusky-tipped, sometimes inconspicuously (Ref. 9997).

A little-known inshore, coastal pelagic species (Ref. 9997). Feeds mainly on fishes, also takes crustaceans and cephalopods (Ref. 6871). Viviparous (Ref. 50449). Probably taken in fisheries where it occurs (Ref. 9997). Utilized fresh and dried salted for human consumption; fins used in the oriental shark fin trade; liver oil processed for vitamins (Ref. 9997).
Viviparous, placental (Ref. 50449). 3 in a litter (Ref. 6871); 2-8 pups per litter (Ref.58048). Gestation period of 9-10 months (Ref. 6871). Size at birth 52 to 55 cm TL (Ref. 9997). Distinct pairing with embrace (Ref. 205).
