Justification:
This undescribed species belongs to a genus of poorly known deepwater catsharks. Very little is known of its biology. This species is known to occur in deepwater (840 to 1,380 m) off New Zealand, sporadic sites around Tasmania and a small area of Western Australia. There is some concern for this species as its distribution includes some heavily fished areas. Deepwater demersal trawl fisheries are expanding in the region, and assuming its biology is like other deepwater shark species, it may not be sufficiently fecund to withstand the exploitation pressure.

Geographic Range [top]

Range Description: This undescribed species is known as Apristurus sp.D. in Last and Stevens (1994). Further research is required to resolve species problems in this genus. It is found at depths of 840 to 1,380 m and appears to extend further down the continental slope than most other Apristurus species.

Population Trend: Unknown

Habitat and Ecology [top]

Habitat and Ecology: This deep-water catshark is the largest member of the genus found in Australia. It reaches at least 86 cm, with males maturing at about 67 cm. Biology is virtually unknown.
Systems: Marine

Threats [top]

Major Threat(s): The known distribution of this species includes some heavily fished areas, particularly off southern Australia. This species has not been recorded from the SETF, but this may be due to the similarity of this genus, resulting in all specimens being identified as Apristurus sp. A. These catsharks are possibly rare (T.I.Walker, pers.comm.). Off New Zealand, it is also likely to be affected by trawl fisheries, although as relatively little fishing occurs below 1,200 m depth some of the population occurs beyond fishing depths.
