Taxonomy [top]

Kingdom Phylum Class Order Family

Scientific Name: Sepia gibba
Species Authority: Ehrenberg, 1831

Assessment Information [top]

Red List Category & Criteria: Data Deficient ver 3.1
Year Published: 2012
Date Assessed: 2009-03-23
Assessor(s): Barratt, I. & Allcock, L.
Reviewer(s): Reid, A., Rogers, Alex & Bohm, M.
Contributor(s): Herdson, R. & Duncan, C.
Sepia gibba has been assessed as Data Deficient as almost nothing is known about this species. The suggestion that it occurs in very shallow water and its limited distribution within the Red Sea mean it might be particularly susceptible to development and other anthropogenic impacts. Further research is recommended before an accurate assessment of this species can be carried out.

Population Trend: Unknown

Habitat and Ecology [top]

Habitat and Ecology: This species attains a mantle length of up to 100 mm (Reid et al. 2005). It is associated with coral reefs in the Red Sea where it hides amongst the spines of venomous urchins (Diadema sp.) at night (Nesis 1987).
Systems: Marine

Use and Trade [top]

Use and Trade: This species is of no current interest to fisheries (Reid et al. 2005).

Threats [top]

Major Threat(s): Ocean acidification caused by increased levels of carbon dioxide in the atmosphere is potentially a threat to all cuttlefish. Studies have shown that under high pCO2 concentrations, cuttlefishes actually lay down a denser cuttlebone which is likely to negatively affect buoyancy regulation (Gutowska et al. 2010).

Conservation Actions [top]

Conservation Actions: This species is associated with Coral Reefs in the Red Sea and monitoring of this habitat is necessary. Further research is recommended regarding the population trends, distribution, life history traits and threats impacting this species.
