Conus tenuilineatus 


Taxonomy [top]

Kingdom Phylum Class Order Family
Animalia Mollusca Gastropoda Neogastropoda Conidae

Scientific Name: Conus tenuilineatus
Species Authority: Rolán & Röckel, 2001
Taxonomic Notes: The southern population found in the Namib Province may be a different species so it has not been included in this assessment; however, if validated, this would extend the range of this species presented in this assessment (M. J. Tenorio pers. comm. 2011); see original description in Rolán & Röckel 2000.

Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2012
Date Assessed: 2011-10-29
Assessor(s): Tenorio, M.J.

This species occurs in an area with no perceived current threats. Oil prospecting has been carried out along Angola's coast and eventual oil exploration may have an effect on Angola's coast in the future, but there is no current development of these activities. At present, however, the species has been classified as Least Concern.

Geographic Range [top]

Range Description: This species is endemic to southern Angola where it is found from Benguela at its northernmost extent to Santa Maria in the south (Monteiro et al. 2004), a coastal distance of approx 150 - 160 km along a shoreline with many bays and promontories. There is a possible population of the species in the south, in Namib province, but this needs confirmation; if validated, this would extend its known range (see original description - Rolán & Röckel 2000).

Population [top]

Population: There are no records of population levels for this species in the literature, which has only recently been described.
Current Population Trend: Unknown
Additional data:
Continuing decline of mature individuals: Unknown
Extreme fluctuations: Unknown Population severely fragmented: Unknown

Habitat and Ecology [top]

Habitat and Ecology:

Adults of the species typically grow to 25 mm in length. It is found in shallow water at depths of 1-3 m buried in sand and pebbles (Rolán & Röckel 2000).

Systems: Marine

Use and Trade [top]

Use and Trade: The shells of this species are traded for the specialist Conus shell market only. As a result, the level of off-take would be low (M. J. Tenorio pers. comm. 2011). At present there are no examples of this species on the collector market.

Threats [top]

Major Threat(s): There are no threats to this species. Oil prospection has been going on along the Angolan coast, but there is no further development on this at the moment so this is not considered a current threat; it may be more significant in the future if oil drilling commences (M. J. Tenorio and S. Veldsman pers. comm. 2011).

Conservation Actions [top]

Conservation Actions: This species has only recently been described and would benefit from further research. There are no known conservation measures currently in place for this species.
