In addition, the special properties of squid are also widely concerned in exploring cosmic life and developing personalized medical care.
Squid, as an important species of molluscs, not only has rich cultural significance, but also is one of the hot spots leading the future development of science and technology. However, in view of the sustainability and durability of its development, we need to strengthen protection and rational utilization to ensure the balance between its ecological function and human interests.
