Habitat and Ecology
Bathydemersal deepwater species found at 406–911 m on or near the bottom on insular slopes (Compagno in prep.). The holotype is immature at 17 cm TL and maximum size is reported to 46 cm TL; however the species is known from very few specimens and its biology is virtually unknown (Compagno in prep.).

Justification
Etmopterus villosus is a little known lanternshark endemic to Molokai in the Hawaiian Islands and found on or near the bottom at 406–911 m depth. The species is known from few specimens and has been reported to a maximum of 46 cm total length. Although this species is poorly known, it occurs beyond the range of current fishing pressure and there is no reason to suspect that the population has declined. It is therefore assessed as Least Concern, but if deepwater fisheries begin to operate within this endemic species’ limited range in the future, it will need to be reassessed.

Major Threats
The bottom fish fishery operating in the Hawaiian Archipelago targets deepsea snappers (Etelis and Pristipomoides species), which are most common at <300 m depth (DLNR 2002). This species occurs beyond current fishing pressure. Any development of fisheries to greater depths in the region should be closely monitored to ensure that this endemic species is not adversely affected.

Conservation Actions
The biology of this species is virtually unknown. Like many deeper water species more information on biology, ecology and importance in fisheries are required to further assess status and any future conservation needs. Further surveys would benefit in the collection of data on the wider depth distribution and range of the species.

The development and implementation of management plans (national and/or regional e.g., under the FAO International Plan of Action for the Conservation and Management of Sharks: IPOA-Sharks) are required to facilitate the conservation and management of all chondrichthyan species in the region.
