The species is found near the city of Dakar, where the species 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 is probably decreasing. In the south the disturbance comes from recreational activities associated with tourism complexes. Hence the species is assessed as Endangered B1ab(iii)+2ab(iii).
|Range Description:||This species is endemic to Senegal where it is found from Oukham in the Cap Vert Peninsular (Dakar) to Pointe Sarène in the south; a coastal distance of approx 117 km. A separate and distinct population occurs off Gorée Island at the southern tip of the Dakar peninsular (Monteiro et al. 2004). It is more frequent in the southern part of the range than some other species.
There is no information on the fragmentation of this species. However, much of the land adjoining the entire length of this coast has been developed. Dakar at the northern end of its range is a large metropolis (pop 2.5 m) with resultant industrial and commercial pollution risk and Mbour (pop 0.2 m) near the southern end is also source of serious marine pollution (UNEP 2009).

|Population:||There are no data on population levels for this species, but decline is inferred as it occurs in exposed habitats within polluted areas. The size of the specimens taken has been reducing over the last 15 years and the population of the species is probably decreasing (E. Monnier pers. comm. 2011).|
|Habitat and Ecology:||This species is found in shallow water below low tide as well as on rocky reefs (M. J. Tenorio pers. comm. 2011). Adults of the species typically grow to 40-45 mm in length.|
|Use and Trade:||
There is some shell collecting but generally there is a low volume of offtake for trade (E. Monnier pers. comm. 2011).
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). In southern part of the range there is disturbance due to tourism activities.
There is a low level of trade in specimen shells for sale, as the market is quite specialist.
|Conservation Actions:||There are no known conservation measures currently in place for this species.|
