पर्यावरण: पर्यावरण / जलवायु क्षेत्र / गहराई सीमा / वितरण सीमा पारिस्थितिकी
समुद्री pelagic-oceanic; गहराई सीमा ? - 300 m (Ref. 75154). Tropical; 8°S - 28°S
पृष्ठीय रीढ़ (सम्पूर्ण) : 0; गुदा कांटा: 0. Brownish grey above, white below, fins light-edged but not conspicuously marked (Ref. 9997). Body shape (shape guide): fusiform / normal.
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).
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).
