Justification
This species has been considered endemic to Martinique (near La Vauclin). The range of this species may continue to Saint Lucia, although this requires further evidence. It is a shallow water species. This species is highly restricted in its range with an approximate AOO of 100km2. There has been a lot of urban and tourism coastal development in recent years which poses a threat to this species' habitat. As with all Conus spp it is subject to gathering which could place additional pressure on populations especially as it inhabits shallow water. This species actually triggers the Endangered category under B2 a) and b). However, Petuch feels that this category may be too high as there has been no noticeable decline in population. Therefore this species is listed as Vulnerable.

Threats

Major Threats
This species is restricted in its range, occurring along a coastline of approximately 50 km. Threats include urban and tourism development along the coastline and loss of habitat (Petuch pers. comm. 2011). As with all Conus spp it is subject to gathering which could place pressure on populations.

Management

Conservation Actions

Conservation Actions
This species is restricted in its range and very scarce in the market and would benefit from further research into populations, distribution, habitat, level of off-take and threats before any action plan can be formulated. There are no known conservation measures currently in place for this species.

Conus hennequini

Conus hennequini 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.
