Assessment Information [top]

Red List Category & Criteria:	Endangered B1ab(iii,v)+2ab(iii,v) ver 3.1

Justification: 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).
