Ecology

Habitat

Habitat and Ecology

Habitat and Ecology
This species occurs at depths of around 30-40 m, typically on coarse sand and coral rubble near coral reefs (Röckel et al. 1995). Adults of the species will typically grow to approx 30 mm. The species ranges deeper in the Jeddah region than in the Gulf of Aqaba (G. Raybaudi pers. comm. October 2011. It has a lecithotrophic larva as inferred from the protoconch, which probably restricts its range by restricting its dispersal (G. Raybaudi pers. comm. October 2011). The closest species by comparison is Conus clarus from South Australia.

Justification
This species has been found in the Red Sea at the north in the region of Aqaba and in the south in the region of Jeddah, Saudi Arabia and the Dahlak Islands off Eritrea.Very little is currently known about this species. It may be affected by threats such as pollution, but because little is known about its distribution, it is impossible to evaluate the impacts of these threats. More research is needed to construct a meaningful assessment. This species is listed as Data Deficient.

Threats

Major Threats

Prior to 1970, the coasts surrounding the Red Sea lacked any large settlements but small-scale tourism aimed primarily at divers and backpackers was promoted and since then, the attractions of scuba diving and snorkelling, coupled with the Red Sea’s proximity to Europe have expanded traditional Bedouin villages into major tourist resorts (Hawkins and Roberts 1996). The increase in tourism has therefore brought about an increase in coastal developments and damage to reefs through trampling. Coasts within the Red Sea are also under threats derived from urban developments, sewage discharges, shipping and associated spills and pollution. Other types of marine pollution resulting from agricultural growth and development may also be affecting coastal areas (UNEP 1997). However, very little is known about this species' precise distribution, so that the impact of threats cannot currently be evaluated.

This species is only known from three areas of which two, Jeddah and Aqaba, are coastal cities. It may occur further afield (G. Raybaudi and S. Veldsman pers. comm. October 2011). Dahlak is a marine park which may offer some protection to this species. Overall, there is very little data available on which to base an assessment.

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, apart from protection of the Red Sea which provides protection from collection.

Wikipedia

Conus hamanni

Conus hamanni 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.
