Scientific Name: Conus angioiorum Röckel & Moolenbeek, 1992
Taxonomic Notes: This species resembles C. jickelii from Djibouti (see RKK 95; G. Raybaudi pers. comm. October 2011).

Assessment Information [top]

Red List Category & Criteria: Data Deficient ver 3.1
Year Published: 2013
Date Assessed: 2011-10-26

This species occurs off Djiboutii and possibly Eritrea. It has a restricted range, but is afforded some protection due to the protected status of the Red Sea. However, little is known about this species as there are no recent records. There are potential threats in the area, but it is currently impossible to asses the effects of these on this species. More research is therefore needed in the species' population, distribution, habitat and potential threats and it has been listed as Data Deficient.

Geographic Range [top]

Range Description:This species of cone snail occurs off Djiboutii. It is also thought to occur off Eritrea, Kenya and Madagascar (Röckel et al. 1995), but these occurrences need verification. For the purposes of this assessment the populations outside the Red Sea have been omitted.  

In the event that it is endemic to Djibouti and Eritrea on the Red Sea, its EOO and AOO will be restricted to approx 2,000 km2 .
Countries occurrence:
Djibouti; Eritrea
FAO Marine Fishing Areas:
Indian Ocean – western
Additional data:
Estimated area of occupancy (AOO) - km2:2000
Lower depth limit (metres):30
Upper depth limit (metres):5

Population [top]

Population:There is no population information available for this species. There are no recent specimens reported for this species, which may be explained by the protection of the Red Sea area which prohibits collection.
Current Population Trend:Unknown
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:Little is known about the habitats and ecology of this species but it has been found to occur on sand to depths of around 30 m. Adults of the species will grow to approx 45 mm although they will typically be less than this (Röckel et al. 1995). It has a lecithotrophic larval development as inferred from the protoconch.

Use and Trade [top]

Use and Trade:

In common with all Conus spp, this species is traded for the collector market. There are no quantitative data available on the number of shells removed. There are no shell specimens currently for sale (Rice 2007), however, all collection is forbidden in the Red Sea.

Threats [top]

Major Threat(s): Djibouti’s reefs are under similar threats to those being experienced in the entire Red Sea area. These being threats derived from tourism, sewage discharges, shipping and associated spills and pollution, with pressures particularly high around the capital city. Shipping is an important commercial sector as Djibouti is the major harbour for Ethiopia. Anchor, boating and tourism damage is increasing, with little increase in environmental awareness. International tourism is just developing and damage so far is limited. There is low level subsistence fishing and limited exploitation of fish for live export but aquarium fish collecting is increasing (Maghsoudlou et al. 2008). Currently, there is no collection of this species in the Red Sea, as all collection in the area is prohibited.

Conservation Actions [top]

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. The Red Sea now has protected status, forbidding collection.
