Is Squid a Fish? Uncovering the True Identity of Squid

Squid is not a fish, but a mollusk that lives in the ocean, and does not belong to the category of fish. It belongs to the phylum Mollusca, class Cephalopoda, subclass Coleoidea, superorder Decapodiformes, order Oegopsida, suborder Oegopsina.

Squid actually belongs to the shellfish group

Squid and cuttlefish are “relatives”; in fact, it is not a fish, but a kind of shellfish, except that its shell has degenerated and become a white internal skeleton. The squid has a long, narrow body, somewhat like the head of a javelin, so it is also called the spear squid.

Squid is 24K pure shellfish. Shellfish is equivalent to the phylum Mollusca, and squid is the common name for some of the organisms within it that belong to the class Cephalopoda. Strictly speaking, the name “squid” is not scientific, because this term was a common name coined decades ago for economic reasons based on the classification system at that time, but by the beginning of this century mainland China had basically accepted the new classification system for the class Cephalopoda, which differs greatly from the original classification system. The taxonomic units to which the species referred to as squid belong have also been split apart and divided up, so scientifically speaking this name is no longer of much significance.
