Justification
This species is endemic to the Cape Verde Islands where it is has only been found along a 5 km length of coast in the bay at Derrubado in the north of the island of Boavista. It is usually common in the range during the breeding season. No changes have been seen in the population during monitoring over last eight years, so it is considered stable (M.J. Tenorio pers. comm. 2011). There is limited offtake from this site at present as there is no road access to get to the bay and their small size makes them less appealing than larger shells except to specialist collectors. However, Boavista in particular and Cape Verde generally is undergoing an explosive growth in tourism and associated development which may affect future populations of this species. Although this species is restricted to a single site, there are no current threats, but if harvest levels were to increase in future this may cause the species to decline. However, this is unlikely to make the species Extinct or Critically Endangered in a very short time, therefore it is listed as Near Threatened.

Threats

Major Threats
This species is endemic to the island of Boavista, Cape Verde where it is restricted to approximately 5 km stretch of coast at a single site. There was a small exclusive tourist resort, about 3 km from the site, but at present it is unlikely to impact the bay. However, Boavista in particular, and Cape Verde generally, is undergoing an explosive growth in tourism and associated development (Instituto Nacional de Estatística Cabo Verde, http://www.ine.cv/). This may affect future populations of this species through gleaning and habitat disturbance, although the current level of off-take does not seem to impact the species (Manuel J Tenorio pers. comm. 2011).

Wikipedia

Conus derrubado

Conus derrubado is a species of sea snail, a marine gastropod mollusk in the family Conidae, the cone snails and their allies.[2]

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.

Description[edit]

The size of an adult shell varies between 14 mm and 33 mm. This species risks extinction because of its limited range and shallow habitat.

Distribution[edit]

This marine species is endemic to Boavista Island, Cape Verde Islands, living among zoantharians. It is an insular endemic of Boavista. This species may be considered at high risk of extinction because of its limited range and shallow habitat. [2]
