Squid belongs to seafood.

Squid, or Chinese gun squid, is a marine cephalopod mollusk of the genus Gunsquid in the Gunsquid family of the order Gunsquid. The squid has an elongated body with ten tentacles surrounding the mouth, eight longer and two shorter, a reduced inner shell and a pair of triangular or rounded fins. There are 30 species of squid in the whole genus, with 10 species in China.

Squids are found along the coasts of Fujian and Guangdong and in the South China Sea, and also in Japan, Korea, Southeast Asia and New Zealand, inhabiting the seabed of the general shelf. Squid has the habit of grouping and fighting, and like cuttlefish can constantly change color to adapt to the surrounding environment, taking fish, shellfish, crustaceans and other food.

Squids are dioecious and swim close to the shallow sea during the breeding season, spawning on the seabed and attaching to objects such as seaweed or sunken logs. Spring to fall for the spawning period, June to August each year for the bloom period. Lifespan is only 10-18 months.

Life Habits:

Squids are often active in the middle and upper layers of the shallow sea, with a vertical range of movement of up to more than 100 meters. Feeding on krill, sardines, silver hansom fish, small males, etc., and itself a prey for ferocious fish. Eggs mature in batches and are produced in batches, the eggs are encased in gelatinous egg sheaths, each egg sheath encasing a few to several hundred eggs depending on the species, and the amount of eggs produced by different species varies greatly, from several hundred to several tens of thousands.

Chinese gun squid, annual output of 40-50,000 tons, the main fishing grounds in China's Bohai Sea, southern Fujian, Taiwan, Guangdong and Guangxi offshore, as well as the Philippines, Vietnam and Thailand offshore.

On April 4, 2022, the Okinawa Institute of Science and Technology Graduate School (OIST) in Japan issued a paper announcing the results of a recent study in which scientists discovered an elliptical squid that can camouflage itself from predators by changing the color of its body. While octopuses and cuttlefish are known for their ability to "camouflage" themselves, this is the first time a squid has been found to have this ability.
