Overview

Distribution

Range Description

This species occurs off islands throughout the Indian Ocean, ranging from Réunion to the Maldives and Seychelles; it also occurs around Christmas Island (Röckel et al. 1995). At Christmas Island, this species occupies a unique niche; only seven specimens are known but the species is extant. It is found on coral walls in caves, 30-60 m deep. The Christmas island population is isolated from other populations (H. Morrison pers. comm. 2011). The EOO, AOO, and number of locations for this species exceed the criteria for B1, B2, and D2 classification.

Justification
This species occurs off islands throughout the Indian Ocean, ranging from Réunion to the Maldives and Seychelles, it also occurs around Christmas Island with some of these locations being marine protected areas. There is a small threat from recreational divers. The isolated Christmas Island population is likely to be threatened, or at least vulnerable to threat, due to its close proximity to a major loading port for the phosphate mining industry. Although the species occurs in fairly deep waters at the Christmas Island site, any shipwrecks or spills near the cone snail site could have an impact on this isolated subpopulation. This species is listed as Least Concern.

Threats

Major Threats
Due to this species being in reach of recreational divers it is possible that gathering by tourists is a threat especially in areas such as the Maldives where there are designated diving sites which may be in the species' range (www.protectedplanet.net). However, the species generally occurs in protected waters in large parts of its range. Collecting is therefore not considered a major issue, but more a potential localized threat.

Christmas Island population: This subpopulation should be considered as vulnerable as there are few known specimens and there is a phosphate mine on the island with significant potential for pollution; the mine has been there for some time and the main bay of Chrsitmas Island has already been dramatically affected as this is the loading point for phosphate and only 4 km from the site of the cone snail population. There are no other threats as it is a deepwater species and generally inaccessible (H. Morrison pers. comm. 2011).

Management

Conservation Actions

Conservation Actions
There are several marine protected areas within the species' range including Baie Ternay Marine National Park, and Cousin Island Special Reserve in the Seychelles (www.protectedplanet.net). The Christmas Island population is at considerable risk and would benefit from protective measures.

Wikipedia

Conus barthelemyi

Conus barthelemyi is a species of sea snail, a marine gastropod mollusk in the family Conidae, the cone snails and their allies.[1]

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.
