Justification
This is a deep water species endemic to New Caledonia and the Chesterfield Islands in the southwest Pacific. There are no records of population levels for this species in the literature. It is believed to be sporadic and locally uncommon. In the 1990s and early 2000s there was 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 probably 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, and very inaccessible unless dredged. It is listed as Data Deficient.

Wikipedia

Conus richeri

Conus richeri is a species of sea snail, a marine gastropod mollusk in the family Conidae, the cone snails and their allies.[1]

Like all species within the genus Conus, these snails are predatory and venomous. They are capable of "stinging" humans, therefore live ones should be handled carefully or not at all.
