Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2012
Date Assessed: 2011-10-28
Assessor(s): Tenorio, M.J.
Reviewer(s): Monnier, E. & Seddon, M.
Facilitator/Compiler(s): Seddon, M. & Peters, H.
Justification:
This species is found on the Canary Islands, off the southern shore of Morocco (M.J. Tenorio pers. comm. 2011) as well as the southern shores of Western Sahara and northern Mauritania. In common with all Conus spp. and other molluscs, the shells of this species are traded for the specimen shell market, however the levels are considered low-take and not impacting the species. Neither is there take for curio production in Mauritania. There are only very localised threats from pollution and hence the species is considered to be Least Concern.

Geographic Range [top]

Range Description: This species is found on the Canary Islands, with presence at Lanzarote, Fuerteventura, Tenerife, Gran Canaria and the small island of Graciosa off the northern coast of Lanzarote and the islet of Los Lobos off the northern coast of Fuerteventura.  There are no populations among the islands of the Western Canaries.  Further populations are found off the southern shore of Morocco (M.J. Tenorio pers. comm. 2011) as well as the southern shores of Western Sahara for approx 170 km and northern Mauritania for approx 230 km (Monteiro et al. 2004). Populations occurring in the Canary Islands can be found along approx 900 km of coast. Populations occurring in Northern Mauritania are found in the waters of the Banc Darguin National Park marine reserve.
