Épines dorsales (Total): 0; Rayons mous dorsaux (Total): 0; Épines anales 0; Rayons mous anaux: 0. Brownish grey above, white below, fins light-edged but not conspicuously marked (Ref. 9997).

Biologie     Glossaire (ex. epibenthic)

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).

Life cycle and mating behavior Maturité | Reproduction | Frai | Œufs | Fécondité | Larves

Viviparous, with a yolk-sac placenta (Ref. 9997) and 1-10 pups after a gestation period of 11-12 months; born at ~ 25 cm TL; very rapid growth (Ref.58048). Distinct pairing with embrace (Ref. 205).
