Justification:
This deep water species has a restricted range, where it is endemic to New Caledonia and the surrounding islands, many being collected from the Isle of Pines.  It has a depth range of 200-525m.

There has been in the 1990s and early 2000s commercial dredging in New Caledonia for sharkteeth and shells including this species, however, these practices have mostly ceased from exhaustion of sharkteeth and closure to dredging of species rich seamounts on the Norfolk Ridge.  There are still stocks from these previous dredges of this species available for the specimen shell trade. Some of the area exploited for shark teeth and shells have likely been excessively exploited, but not believed to affect the global population of this species. There is some control on the amount of off shore dredging in New Caledonia but it is very inaccessible except to dredgers.  It is listed as Least Concern.

Habitat and Ecology [top]

Habitat and Ecology:This species can be found on seamounts and knolls primarily on gravel and hardbottom substrate (Appeltans et al. 2011 from the WoRMS database), and is a deep water species, ranging from 200 to 525 m in depth (Röckel et al. 1995). Adults of this species can grow to 22 mm although they will typically be less than this (Poppe and Poppe 2011).
Systems:Marine
Continuing decline in area, extent and/or quality of habitat:Unknown

Use and Trade [top]

Use and Trade:

There has been in the 1990s and early 2000s commercial dredging in New Caledonia for sharkteeth and shells including this species, however, these practices have mostly ceased from exhaustion of sharkteeth and closure to dredging of species rich seamounts on the Norfolk Ridge (Bouchet pers. comm. 2011).  There are still stocks from these previous dredges of this species available for the specimen shell trade.

Threats [top]

Major Threat(s):

Some of the area exploited for shark teeth and shells have probably been excessively exploited, but not believed to affect the global population of this species (Bouchet pers. comm. 2011).

Conservation Actions [top]

Conservation Actions: There is some control on the amount of off shore dredging in New Caledonia but it is very inaccessible except to dredgers.
