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).

Sepia bartletti

Sepia bartletti is a species of cuttlefish native to the western Pacific Ocean. It is known only from the type locality. Depth range is unknown.[1]

S. bartletti is known from only the holotype and six other specimens (all cuttlebones) described by Tom Iredale in 1954. It is possibly a junior synonym of Sepia bandensis.[1] The placement of S. bartletti in the genus Sepia is also questionable.[2]

S. bartletti grows to a mantle length of 74 mm.[1]

The type specimen was collected in the Misima and Conflict Group of the Louisiade Archipelago, to the southeast of Papua New Guinea. It is deposited at the Australian Museum in Sydney.[2]
