Overview

Distribution

Range Description

This species occurs around Madagascar and Mozambique and south to central Natal, living in intertidal zones and down to 20 m (Röckel et al. 1995, Monteiro 2011). However, the records from Madagascar are doubtful at present (G. Raybaudi pers. comm. October 2011).

The EOO, AOO, and number of locations for this species exceed the criteria for B1, B2, and D2 classification.

Justification
This species occurs around Madagascar and Mozambique and south to central Natal, living in intertidal zones and down to 20 m. However, the records from Madagascar are doubtful at present. This species has no known major threats to its population. Localized pollution may affect intertidal populations, but this is not thought to be a major threat and although its shell is low price in the market it is now not readily found in most areas. It has been assessed as Least Concern.

Threats

Major Threats
There are no known material threats to this species. Localized pollution from municipal areas, siltation and agricultural run off can affect intertidal populations in certain areas, but this is unlikely to be a major impact on the population (S. Veldsman pers. comm. October 2011).

Conus iodostoma

Conus iodostoma, common name the violet-mouth cone, 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.
