Octopus sashimi, shredded squid and cuttlefish stewed chicken soup are all favorites of food lovers, but if you only look at the actual biological pictures, they are all big eyes and soft tentacles. It is estimated that most food lovers can't name them at once. In addition, these three marine creatures have many flower names, such as squid, cuttlefish, cuttlefish and octopus. These are hard to avoid dazzling, and I don't know what kind of fish this is. Let's take a closer look at the differences between these three delicious ingredients.

octopus

First of all, from the name, octopus is an alias octopus, squid is an alias squid, and squid is an alias squid and squid ... well, it seems meaningless to distinguish them. Let's skip it.

Secondly, from the taxonomic point of view, octopus, squid and cuttlefish all belong to mollusk cephalopods. Cephalopods are characterized by a funnel-shaped foot on the head and a wrist (also known as tentacles). Octopus belongs to Cephalopoda, squid and cuttlefish belong to Cephalopoda. In other words, counting the number of tentacles can roughly distinguish octopus from the latter two cephalopod brothers.

? cuttlefish

Finally, from the appearance, octopus, squid and cuttlefish can be divided into three parts: head, feet and mantle. The mantle of octopus is spherical, the mantle of squid is conical, and the mantle of squid is bag-shaped. Squid is more slender than cuttlefish, and the end of the mantle looks like a javelin head, so it is called cuttlefish. If you still can't tell squid from cuttlefish, you can try to press the middle of their bodies. Soft is squid, hard is cuttlefish, because the inner shell of squid is horny and thin, while the inner shell of cuttlefish is calcareous. As for octopus, its inner shell has been completely degraded, so it has superb "bone shrinking" skills.
