Threats

Major Threats
Fishing pressure is a potential threat to this species but it is not currently of concern (A. Reid, pers. comm.). 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).

Sepia filibrachia

Sepia filibrachia is a species of cuttlefish native to the South China Sea. Its natural range covers the waters off Taiwan,[a] Haikou on Hainan Island,[b] and Guryanova in the Gulf of Tonkin, Vietnam. It lives at depths of 34 to 95 m.[1]

Females are on average slightly larger than males. They grow to 70 mm and 62 mm in mantle length, respectively.[1]

The type specimen was collected off Ling Yuan, Kaohsiung, Taiwan (22°28′N 120°24′E / 22.467°N 120.400°E / 22.467; 120.400).[1]

S. filibrachia is of commercial interest to fisheries and is marketed in Taiwan.[1]
