? Mollusk is a general term for a group of animals, referring to animals in the phylum Mollusca, which contains many different species. Squid is a kind of common animal in daily life, which belongs to Mollusca, Cephalopoda, Sepiidae. Since squid are also mollusks, they are also mollusks.
As a mollusk, squid also conforms to many characteristics of mollusks. For example, from the point of view of motor organs, the motor organs used by mollusks are generally feet, squid also use feet to move, and there are more than one foot. For example, the body of mollusks is generally soft, and the external structure of the body is generally the mantle, so is the squid, which conforms to this basic feature.
above, squid belongs to mollusks, because they are animals in the phylum Mollusca. Coelenterates, on the other hand, refer to animals within the phylum Coelenterata. Although both mollusks and coelenterates belong to invertebrates, they are two different animals, and there is no intersection between them, so it is impossible for an animal to belong to both mollusks and coelenterates. Therefore, the squid, as a mollusk, is not a coelenterate.
In fact, coelenterates are inferior to mollusks. Their nerves and muscles are just beginning to differentiate, and their body structure is relatively simple. Compared with squid, squid is more advanced and its body structure is more complex.
