Squid, also known as cuttlefish or cuttlefish, is a marine cephalopod mollusk of the order Sepioidea.

Closely related to octopus and squid. Modern squids appeared in the Miocene 21 million years ago, and their ancestors were belemnites. It is characterized by a thick calcareous inner shell (sepia bone, cuttlefish bone or sea cucumber, which can be used as medicine). There are about 350 species of squid, ranging in length from 2.5 to 90 centimeters (1 to 35 inches). The largest giant squid is over 20 meters long. Squids are distributed in all the world's oceans, living mainly in shallow waters along tropical and temperate coasts, and often migrate to deeper waters in winter. Common squid reproduces in spring and summer, laying about 100 to 300 eggs.

The squid's body is like a rubber bag, with its internal organs wrapped inside the bag. There are fleshy fins on both sides of the body, which are used for swimming and maintaining body balance. The head is short with well-developed eyes on both sides. It has a long mouth on the top of its head and horny jaws inside its mouth that can tear food. The squid's legs are on the top of its head, so it is also called cephalopod.

Of the 10 legs on the top of the head, eight are shorter, with dense suction cups on the inner side, called arms; the other two are longer, freely movable legs that can retract into two sacs, called tentacles, and only the inner side of the front end has suction cups. Squids mainly eat crustaceans, small fish or other mollusks, and their main enemies are large aquatic animals. It is the most outstanding smokescreen expert among cephalopods. When encountering an enemy, it will spray out a smoke screen and then escape.

The meat of squid is edible, the ink in its ink sac can be processed for industrial use, the ink sac is also a medicinal material, and the inner shell can be fed to caged birds to supplement calcium. The viscera of squid can be used to produce visceral oil, which is a good raw material for leather making. Its eyeballs can be made into eyeball glue, which is a top-grade adhesive. Common squids in my country include calamari (commonly known as squid), golden squid and needleless squid. Squid is one of the four major seafoods in my country (large yellow croaker, small yellow croaker, hairtail, and cuttlefish). It is caught in large quantities and has delicious meat and rich nutrition.
