This species is mainly found on the northern part of the peninsula, near the city of Dakar. It occurs within the environs of the city with associated marine pollution from the port and factories, as well as disturbance caused by shipping.  The size of the specimens taken has been reducing over the last 15 years and the populations of the species are probably decreasing (E. Monnier pers. comm. 2011). Hence the species is assessed as Endangered B1ab(iii,v)+2ab(iii,v).

Geographic Range [top]

Range Description: This species is endemic to Senegal where it is found only along the western edge of the Cap Vert Peninsula of the capital Dakar, from the districts of Yoff in the north to Dakar-Fann on the southern tip including Madeleine Island, a total coastline of approx 37 km (Monteiro et al. 2004).  The whole of the adjacent land is highly developed and industrialised with associated problems including discharge of pollutants into the marine environment (UNEP 2009).  This species is described as being at its most abundant from the headland in the districts of Almadies on the north-western tip to Ouakam approx 4 km to the south (Monteiro et al. 2004).

In common with all Conus spp. this species is traded by specimen shell dealers for the collector market, but it is not as common as other species from Senegal.

Threats [top]

Major Threat(s): Marine pollution along the whole of this coastline, in particular around the Cap Vert Peninsular, from industrial and domestic discharges including sewage, chemicals and other toxins, presents a severe problem to marine creatures living in the area (UNEP 2009).

Conservation Actions [top]

Conservation Actions: The population on the island lies in a protected area, although there are no known conservation measures currently in place for this species.
