Use and Trade [top]

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: No conservation measures are currently needed for this species and none are in place. Further research is recommended regarding the population trends, life history traits and threats impacting this species.
