Short description Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 0; Anal spines: 0; Anal soft rays: 0. Bronzy-grey above, white below when fresh, fading to greyish or greyish brown in preservation, dorsal fins often with dusky or black tips (Ref. 13567).

A common inshore and offshore shark found on the continental and insular shelves (Ref. 13567). Probably feeds on small fishes, cephalopods, and crustaceans (Ref. 244). Viviparous (Ref. 50449). Caught irregularly by inshore gillnet fisheries and occasionally by small-scale longlining (Ref.58048). Probably taken by artisanal fisheries wherever it occurs (Ref. 13567). Utilized fresh for human consumption and by-products processed into fishmeal (Ref. 244).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Viviparous (with a yolk-sac placenta), with 4 young in a litter (Ref. 244). Size at birth at least 20 cm (Ref. 244). Distinct pairing with embrace (Ref. 205).
