Justification
This species is endemic to the Cape Verde Islands where it is found at Tarrafal off the southwest coast of the island of São Nicolau. There are several scattered records of the species from around the island. The centre of distribution lies off a small town with a harbour, with low levels of pollution (sewage, runoff and oil spills). The other sites are less accessible as there is no road linking to the main town. This species is highly restricted in its range and there are no known conservation measures currently in place.The species is assessed as Near Threatened on a precautionary basis due to small range, restricted number of locations and low level threats.

Conservation Actions
This species is highly restricted in its range and there are no known conservation measures currently in place for this species.
In common with all small Conus spp., the shells of this species are only traded for the specialist collector. When recently collected the shells are almost black. Their small size (typically 22 mm) and superficial damage makes them less appealing than larger shells.

Conus kersteni

Apertural and abapertural views of shell of Conus kersteni Tenorio, M.J., C.M.L. Afonso & E. Rolan 2008, showing variation in the species.

Conus kersteni 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.
