Habitat and Ecology

Habitat and Ecology
This species is found in a variety of neritic habitats (Reid et al. 2005). The sex ratio is 1:1 and growth rates are similar for both sexes, although females attain the largest body sizes (Reid et al. 2005). Spawning occurs year round in the Gulf of Thailand with peaks from March to April and July to September; spawning occurs in depths between 10 and 50 m (Reid et al. 2005). Around India mature individuals are present throughout the year with spawning peaks between January and April (eastern), and in April, July and December (southwestern) (Reid et al. 2005). In Hong Kong spawning occurs in depths of 5 to 20 m from March to May (Reid et al. 2005).

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 major threat to the needle cuttlefish is unregulated fishing (Reid et al. 2005). There are commercially important fisheries around India, Sri Lanka, Thailand, southern China and Taiwan, Province of China; the species is caught using a variety of gear types (Reid et al. 2005). Around Hong Kong mature individuals are harvested during the spawning season (Reid et al. 2005).
