Habitat and Ecology [top]

Habitat and Ecology: This species is found under rocks in shallow water of 0.5 to 3 m (Poppe and Poppe 2011).  Adults of the species typically grow to 28 mm in length.
Systems: Marine

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 28 mm) and superficial damage makes them less appealing than larger shells.

Threats [top]

Major Threat(s): This species is highly restricted in its range, being found along a single 4.5 km stretch of coastline on the island of Boavista. However, it is far from any developments with no road access, and hence there are no threats.
