Justification

This species is endemic to the Cape Verde Islands where it is found off the east coast of the island of Sal. Although this species is highly restricted in its range and currently relatively scarce in the market there are no known threats nor future plans for development and hence there are no known conservation measures currently in place for this species. The species is considered to be Least Concern. Should any threat appear then the revised status would be Vulnerable D2.

Threats

Major Threats

This species is endemic to a 9 km length of shoreline on a single island in the Cape Verde group. There is a hotel in the south of the range but the species has not been affected by this activity. There are no plans to further develop this area at present, and so there are no known threats. There is little collecting activity for this species (M. J. Tenorio pers. comm 2011).

Conus serranegrae

Conus serranegrae 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.
