Short description

Dorsal spines (total): 0; Anal spines: 0. Brownish grey above, white below, fins light-edged but not conspicuously marked (Ref. 9997).

A little-known shark (Ref. 9997) found on the continental shelf from close inshore to a depth of at least 110 m (Ref. 6871). Feeds mainly on fishes, but also takes cephalopods and crustaceans (Ref. 6871). Viviparous (Ref. 50449). Caught frequently by inshore demersal gillnet fisheries off Papua, but rarely elsewhere. Utilized for its fins and meat (Ref.58048). Too small to be of any commercial importance (Ref. 6871).
