Justification
Sepia dollfusi has been assessed as Data Deficient as limited information is available concerning its population status and impacts of harvesting and even its depth range remains unknown. However there is evidence that this species is experiencing at least some fishing activity. Until the level of this activity is clarified this species cannot be accurately assessed.

Threats

Major Threats
Fishing activity is a possible threat to this species but insufficient data exist as to the current level of exploitation. 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).
