Let's sort them first and see where they start to separate. Octopus, squid and cuttlefish, nicknamed the "soft three brothers." They are mollusks that live in the ocean, and they are molluscs-cephalopods. That is to say, if divided from this class, octopus, squid and squid are still a family, all of which belong to the class Cephalopoda (i.e. Dibranchia). From this level, octopus is classified as Octopsida, squid and squid as Decapsida, and squid as Sepiida. At the family level, the three species were completely separated. Octopus belonged to the octopus family, squid belonged to the squid family, and squid belonged to the squid family.

In what ways do they differ?

1. Different body structures

Drinking beer while eating seafood causes purine, glycoside acid and vitamin B1 to mix together, causing chemical action, which will lead to an increase in uric acid content in human blood and destroy the original balance; uric acid cannot be excreted in time and precipitates in the form of sodium salt, which is easy to form stones or cause gout.
