This species is highly restricted in its range, being found only along the northern coast of Boa Vista Island.  However there are no known threats in this part of the island, the species is quite common in suitable habitats and there is limited off-take for the species, hence it is assessed as Least Concern.

Geographic Range [top]

Range Description:This species is endemic to Cape Verde islands, on the island of Boavista where it is restricted to a single stretch of coast some 50 km in length in the NE of the island, from Derrubado in the north to Porto Ferreira in the east (Monteiro et al. 2004).  It is one of the most widespread species on Boavista. There are many small sub-populations in suitable habitats along the coast.

Population [top]

Population:This species is usually common in the range during the breeding season and so is considered stable (M. J. Tenorio pers. comm. 2011).
Current Population Trend:Unknown
Additional data:
Continuing decline of mature individuals:Unknown
Extreme fluctuations:UnknownPopulation severely fragmented:Unknown

Habitat and Ecology [top]

Habitat and Ecology:This species has been found under rocks and dead coral at depths of 1 to 5 m. Adults will typically grow to 35 mm in length.

Use and Trade [top]

Use and Trade:

In common with all small Conus spp., the shells of this species are only traded for the specialist collector.  Their small size (typically 35 mm) makes them less appealing than larger shells.  The market with specialist collectors means there is only a very limited take (M. J. Tenorio pers. comm. 2011).

Threats [top]

Major Threat(s):

This species is highly restricted in its range, being found only along the northern coast of Boa Vista Island.  However there are no known threats in this part of the island (M. J. Tenorio, pers. comm. 2011).

Conservation Actions [top]

Conservation Actions: This species is restricted in its range and scarce in the market and would benefit from further research into abundance, level of off-take and threats before any action plan can be formulated. There are no known conservation measures currently in place for this species.
