睇落應該都係 真烏賊 Sepia esculenta
如果係的話, 咁呢隻真烏賊已經係成熟到最大size, 因為真烏賊的最大體長(唔計個頭)係20cm, 同我地見到呢隻差不多.
真烏賊棲息於10-100m的海域, 偏好內灣的砂泥低, 冬末至初春會游到淺水地方產卵, 所以龍尾其實係好適合佢.
之前見到的Sepiida 烏賊 BB, 好有可能就係佢地的.....
真烏賊在中國海被大量捕獵, 根據IUCN資料, 佢係屬於DD (Data Deficient) 級別
Sepia esculenta has been assessed as Data Deficient as it has a wide geographic distribution and is only fished intensively in certain regions (e.g. East China Sea). Hence the species as a whole is likely unaffected by fishing activity but there are not enough data available to confirm this. Therefore, we currently consider this species to be Data Deficient.
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 fished commercially in the East China Sea and for subsistence off the Philippines (Reid et al. 2005). Its flesh is considered tasty in many Asian countries, for example China and Japan (Reid et al. 2005).
