2. Squid is a mollusk in temperate, subtropical and tropical oceans. When it encounters an enemy, it will spray ink and escape, while dragging its feet and waiting for an opportunity to leave. There are pigment vesicles in its skin, which will change color and size with the change of mood. Mating in late spring, the fertilized eggs are laid on sawdust or hatched into small squid in the sea. Distributed in China, Korean, Japanese, Singaporean, China, Taiwan Province and China.
