Introducing Sepiida

Cuttlefish, also known as Squid (scientific name: Sepiida), referred to as "Cuttlefish" or "Cuttlefish", is an animal of the mollusc phylum Cephalopod subclass Ten-branched animal. All animals of the Cuttlefish order contain a unique inner shell, called "cuttlefish bone" or "sea octopus", which can be used as Chinese herbal medicine. Although these animals have the word "fish" in their names, they are not fish, but molluscs of the class Cephalopods, belonging to the phylum Invertebrates, so cuttlefish bones are not vertebrae. It is worth noting that because of the confusion in the Chinese biological naming system in the early days, there is a big difference between folk names and scientific naming, so the term "Cuttlefish" alone actually refers to the Ten Armaments (i.e. the general term for cuttlefish and squid); and "Cuttlefish" refers to the Cuttlefish in this article
