[Cuttlefish] is also known as squid fish, cuttlefish, eyefish and so on. The "cuttlefish" or "squid" referred to in China are mostly the two species of Man's needleless squid and golden squid that are mainly produced in the East China Sea. When the squid encounters a strong enemy, it will use "inkjet" as a method of escape and wait for the opportunity to leave, so it has names such as "squid" and "cuttlefish". They have pigmented sacs in their skin that change color and size as "mood" changes. Squids can jump out of the sea and have amazing aerial flight capabilities. Like squid and octopus, they are marine mollusks, and none of the three are fish.

Characteristics of life
Squids prefer to live in the deep waters of the oceans in the open seas. Spawning from the deep sea to the shallow inner bay of the reef in the warm spring season of each year, spawning sticks to seaweed and other objects from April to June, and starting in late September, the hatched larvae of the year return to the south for wintering. Crustaceans, molluscs and other small animals can be preyed upon in migration.
