Habitat and Ecology

Habitat and Ecology
This species is known to occur in shallow water on coral reefs. Adults of the species will grow to approx 55 mm although they will typically be less than this (Röckel et al. 1995). It has a lecithotrophic larval development as inferred from protoconch, with individuals producing typically only 5 to 6 eggs per season.

Justification
This species is endemic to the reefs off Oman, ranging from Muscat south to the island of Al Masirah. It has a restricted range with an extent of occurrence and area of occupancy of less than 2,000 km2. It is likely to be vulnerable to threats from marine pollution, particularly from the petroleum industry, which is widespread in the area. Based on this threat, for which a single threatening event can potentially affect a large area, we infer an occurrence of no more than ten locations. The species was never abundant, but is very scarce now, so it is inferred that there has been a decline in the number of individuals which is likely to be ongoing since the causes are not fully understood and have therefore not been addressed. It is listed as Vulnerable.

Population

Population
There is no quantitative population information for this species. It was never abundant in the market, but is thought to be now very scarce based on reports from collection efforts by trained collectors, with only few juveniles found (G. Raybaudi pers. comm. October 2011). Latest reports from Masirah island suggest the species is very scarce here (G. Raybaudi pers. comm. October 2011).

Threats

Major Threats
Oman is susceptible to the majority of threats faced by countries of the Arabian Sea (Sale et al. 2010). These include (i) chronic contamination of coastal waters due to the continuous discharge of oil from harbours, ballast water, terminals, and sewage-plant effluents (Madany et al. 1998); (ii) discharge of effluent from manufacturing industries including the discharge of heavy metals, oil and petroleum-based compounds, nutrients, and halogenated organics (Gevao et al. 2006); (iii) the clearing and alteration of habitats such as coral reefs, in particular, which have all been altered by coastal dredging and development for industrial, commercial, and residential use (Sheppard et al. 1992, 2010). The main threat affecting this species is pollution, particularly from the petroleum industry, because of the shallow water habitat in which it occurs.

The limited availability of shells in the collector market could be an indicator of lack of abundance in the wild, especially as this is a shallow water species and easily gathered.

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, and threats before any action plan can be formulated. There are no known conservation measures currently in place for this species.

Wikipedia

Conus ardisiaceus

Conus ardisiaceus 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.
