Red List Category & Criteria: Least Concern ver 3.1

Justification:
This deepwater lantern shark is currently recorded only from the continental slope of the central Queensland Plateau off Australia and off New Caledonia. Although the species is known only from two small areas and a narrow bathymetric range, further exploratory trawls may indicate a wider distribution. There are presently no major fishing activities in the known area of occurrence, and if captured it is likely discarded due to its small size and lack of commercial value. Survival rates after discarding, however, are not known. Given the global expansion of deepwater trawl fisheries, future pressure may be placed on this small species and any increase in fishing activities within its range should monitor the catch of this and other etmopterid species closely. At present, however, there is no reason to suspect a decline in range, habitat quality or number of mature individuals.

Habitat and Ecology [top]

Habitat and Ecology: Recorded from near the bottom on the continental slope in depths of 708 to 880 m. Maximum size at least 41 cm total length (TL). Male of 338 mm TL was adolescent. Embryo of 95 mm TL. Nothing else known of its biology.
Systems: Marine

Threats [top]

Major Threat(s): Presently no major fishing activity in its area of occurrence. The species is not targeted in any commercial fisheries. It is unlikely to be captured frequently on longline gear due to its small size. If captured, it is likely discarded (survival rates are unknown but are likely to be moderate from longline capture and low from trawl capture). However given the global expansion of deepwater trawl fisheries pressure may be placed upon small and medium-sized etmopterid species in the future and this situation should be monitored closely.
