Scientific Name: Conus salreiensis Rolán (Mosquera), 1980

Assessment Information [top]

Red List Category & Criteria: Critically Endangered B1ab(iii)+2ab(iii) ver 3.1
Year Published: 2012
Date Assessed: 2011-07-10
Assessor(s): Tenorio, M.J.
Reviewer(s): Monnier, E. & Seddon, M.
Facilitator/Compiler(s): Seddon, M. & Peters, H.
Justification:
This species is endemic to the Cape Verde Islands where it is found only off the northwest coast of Boavista Island at Baía Teodora and Sal Rei along a coast of approx 6 km including a small island. It is restricted to a single bay where it was originally more abundant around the harbour side of the bay and is now more frequent on the islet in the bay (M. J. Tenorio pers. comm. 2011), although always scarce in population samples. This species declined after a major harbour development 10 years ago which impacted the species in the main part of the range, and there is an ongoing low level of risk from pollution.The species is considered to be Critically Endangered B1ab(iii)+2ab(iii).

Geographic Range [top]

Range Description:This species is endemic to the Cape Verde Islands where it is found only off the northwest coast of Boavista Island at Baía Teodora and Sal Rei (Monteiro et al. 2004) along a coast of approx 6 km including a small island. It is restricted to a single bay where it was originally more abundant around the harbour side of the bay and is now more frequent on the islet in the bay (M. J. Tenorio pers. comm. 2011).

Population [top]

Population:The populations around Sal-Rei have been declining but those on the other side of the islet are considered to have been stable over the last 10 years. The species is scarce in suitable habitats during the breeding season in the region (M. J. Tenorio pers. comm. 2011).  The harbour construction 10 years ago impacted the populations.
Current Population Trend:Decreasing
Additional data:

Habitat and Ecology [top]

Habitat and Ecology:This species lives on rocky shores with patches of sand.  The species is found at depths of between 1 and 15 m (Poppe and Poppe 2011).  Adults of the species typically grow to 25 mm in length. Recently, the temperature of the water has increased with colonization by corals.
Systems:Marine
Continuing decline in area, extent and/or quality of habitat:Yes

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 22 mm) makes them less appealing than larger shells, and the shells are hand-picked. Many specimens come from old stocks (M. J. Tenorio pers. comm. 2011).

Threats [top]

Major Threat(s): This species is only found in a single small bay where there was a major harbour development 10 years ago that impacted the species in the main part of its range. There is a low level of risk from pollution.

Conservation Actions [top]

Conservation Actions: This species has a restricted  range and would benefit from further research into abundance and threats. There are no known conservation measures currently in place for this species.
