Descrição suscinta Chaves de identificação | Morfologia | Morfometria

Espinhos dorsais (total) : 0; Espinhos anais: 0. 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).

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).
