Assessment Information [top]

Red List Category & Criteria: Vulnerable D2 ver 3.1
Year Published: 2013
Date Assessed: 2011-10-27

This species is restricted to a single island with a coastline of approximately 69 km. As a shallow water species, occurring in an area with a large tourism infastructure, places it at particular risk. This species is listed as Vulnerable under D2.

Geographic Range [top]

Range Description:This species is endemic to the island of Aruba in the Netherland Antilles group (Coltro pers. comm. 2011).

Population [top]

Population:There is no population information for this species.
Current Population Trend:Unknown
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:This species inhabits the sand and rubble areas of coral reefs where it lives at shallow depths immediately below low tide. Adults of the species typically grow to 21 mm (Rosenberg 2009).
Continuing decline in area, extent and/or quality of habitat:Unknown

Use and Trade [top]

Use and Trade: In common with all Conus spp this species is traded for the specimen shell collector market. It is not often available for sale but where available demands medium prices (Rice 2007). There are no quantitative data available on the number of shells removed but the small size of the shell (21 mm) is likely to make this species less attractive to the general curio trade.

Threats [top]

Major Threat(s): This species is highly restricted in its range, occurring a coastline of only 69 km. As with all Conus spp it is subject to gathering.  Aruba is a densely populated island made over to tourism, and as a shallow water species this must pose a threat despite its small size.

Conservation Actions [top]

Conservation Actions: Part of the range of this species falls into a national park which is protected. There are no known conservation measures currently in place for this species.
