Assessment Information [top]

Red List Category & Criteria:	Data Deficient ver 3.1
Year Published:	2003
Assessor/s:	Fowler, S.L. (SSG Australia & Oceania Regional Workshop, March 2003)
Reviewer/s:	Stevens, J., Cavanagh, R.D., Fowler, S. & Musick, J.A. (Shark Red List Authority)
Justification: Known from only one pregnant female (carrying two near-term pups, suggesting a low intrinsic rate of population increase), collected off a river mouth in water 73 m deep. Presumably an endemic of the New Guinea continental shelf. The extent of occurrence of this species is likely small (less than 20,000 km²), but there is no evidence of major threats to the habitat or significant fishing pressure (this very distinctive species has not been reported from landing sites or markets).

Geographic Range [top]

Range Description:	Unknown (only one specimen recorded). Probably an uncommon endemic; it is very distinctive in appearance and should have been recorded more frequently if common, but the area is not well-surveyed.
Countries:	Native: Indonesia (Irian Jaya); Papua New Guinea
FAO Marine Fishing Areas:	Native: Pacific – western central

Population [top]

Population:	Only one specimen recorded.
Population Trend:	Unknown

Habitat and Ecology [top]

Habitat and Ecology:	Continental shelf, off a river mouth, probably on or close to bottom. Taken on a hand line. Probably feeds on bottom-dwelling species. The type specimen was a pregnant female (74 cm) with a 24 cm near-term foetus. This is an ovoviviparous species with normal litters numbering two pups, indicating low intrinsic rate of population increase.
Systems:	Marine

Threats [top]

Major Threat(s):	Bycatch in shallow continental shelf fisheries.

Major Threat(s):
