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). This species is associated with the Great Barrier Reef. Although this is a World Heritage area, this habitat is under threat due to seawater warming and faces serious declines under current climate projections.

Sepia bidhaia

Sepia bidhaia is a species of cuttlefish native to the southwestern Pacific Ocean, specifically the waters off the Great Barrier Reef (17°20′S 146°41.5′E / 17.333°S 146.6917°E / -17.333; 146.6917 to 22°07′S 153°19′E / 22.117°S 153.317°E / -22.117; 153.317). It lives at a depth of between 200 and 304 m.[1]

Females of this species are slightly larger than males. They grow to a mantle length of 57 mm and 37 mm, respectively.[1]

The type specimen was collected near Queensland, Australia (17°55.8′S 146°58.2′E / 17.9300°S 146.9700°E / -17.9300; 146.9700). It is deposited at the Museum of Victoria in Melbourne.[2]
