Overview

Distribution

Range Description

This species is endemic to the Cape Verde islands where it is found around the northern side of Maio, mainly on the rocky parts of the island, as the southern coasts are sandy. There are records from Pau Seco, Calheta, Ponta Rica, Ponta Pipa, Baía do Navio and Baíado Galeão. This is a coastline of approx 34 km in length (M.J. Tenorio pers. comm. 2011).

Justification
This species is highly restricted in its range being found only within the bays along a strip of 34 km coastline. There are no plans for tourist development and no small harbours, nor any roads to the region, so there are no current threats for this species. The off-take for the shell trade is limited, and as such is not considered a threat. The species is currently considered as Least Concern, but should the area be developed, or there be a road constructed, then the conservation status should be re-evaluated.

Population

Population
This species is usually scattered but frequent in the range during the breeding season (M.J. Tenorio pers. comm. 2011). No changes have been seen in the populations during monitoring over the last 8 years so it is considered stable (M.J. Tenorio pers. comm. 2011). There has been an increase in the numbers of sites, but it is believed to be a reflection of sampling effort not expansion of the range.

Threats

Major Threats

This species is endemic to a 34 km length of shoreline on a single island in the Cape Verde group. There are no plans for tourist development and no small harbours, nor any roads to the region, so there are no current threats for this species. The off-take for the shell trade is limited, and as such is not considered a threat.

Apertural view of Conus infinitus.

Conus infinitus is a species of sea snail, a marine gastropod mollusk in the family Conidae, the cone snails and their allies.[2]

Like all species within the genus Conus, these snails are predatory and venomous. They are capable of "stinging" humans, therefore live ones should be handled carefully or not at all.
