Habitat and Ecology
This species is a neritic demersal species and is usually found on sandy, muddy and rocky habitats (amongst sea pens in the latter) on the continental shelf at approximately 100 m (Norman 2003, Reid et al. 2005). In the spring (March-May) mature individuals migrate to shallower (approximately 20 m), rocky regions to spawn (Reid et al. 2005). The young hatch during the summer and migrate to deeper depths in late summer (Reid et al. 2005).

Justification
Metasepia tullbergi has been assessed as Data Deficient despite a fairly wide geographic distribution because it occurs in an area where fishing pressures are generally high and no data are available as to the level at which it is fished, or of the level of exploitation connected to the aquarium trade.

Threats

Major Threats
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). The paintpot cuttlefish is characterised by bright colours and patterns, and interesting behaviours that could make it popular in the aquarium trade (Reid et al. 2005). It is not collected commercially but could be subject to bycatch and artisanal fisheries (Reid et al. 2005).

Metasepia tullbergi

Metasepia tullbergi, also known as the paintpot cuttlefish, is a small cuttlefish that lives in the seas between Japan and Hong Kong. It is also known as the northern flamboyant cuttlefish. Metasepia tullbergi has been assessed as Data Deficient despite a fairly wide geographic distribution because it occurs in an area where fishing pressures are generally high and no data are available as to the level at which it is fished, or of the level of exploitation connected to the aquarium trade.
