Cuttlefish 烏賊，本名烏賊為俗寫，又稱花枝、墨鬥魚或墨魚，是軟體動物門頭足綱烏賊目的動物。 與魷魚不同的是，烏賊有一船形石灰質的硬鞘。 烏賊的最大特色是它遇到強敵時會以「噴墨」作為逃生的方法，伺機離開，因而有「烏賊」、「墨魚」等名稱。皮膚中有色素小囊，會隨「情緒」的變化而改變顏色和大小。
Simple English Wikipedia: Cuttlefish are marine (海洋) Cephalopod (cephalo = head, pod =
foot ∴ 頭足綱) molluscs (軟體動物). They belong to the same class as squid, octopuses and the nautilus. Cuttlefish have an internal shell (called a cuttlebone), large eyes, and eight arms and two tentacles furnished with finely toothed suckers, with which they grab their prey. Cuttlefish eat small molluscs, crabs, shrimp, fish and other cuttlefish. Various sharks and fish prey on them. They live about 1 to 2 years.
